5 Coffee Bean Roaster Reviews

Here are my in-depth findings on the five best coffee roaster machines. I lived with these roasters, learning their quirks and strengths to help you find the perfect one for your kitchen.

Best Overall for Automated Roasting: 500g Automatic Coffee Roaster Review

The 500g Automatic Coffee Roaster Machine is the ideal choice for the home barista who wants both the push-button simplicity of automation and the option to dive deep into manual roasting. It’s a powerful, versatile machine that grows with you, delivering incredibly consistent results thanks to its intelligent design and robust feature set. If you’re looking for a serious long-term investment in your coffee hobby, this is it.

Specification:
* Roast Capacity: Up to 500g (best performance at 350g-400g)
* Roast Type: Drum Roaster
* Control Modes: Automatic (9 profiles) and Manual
* Voltage: 110V
* Key Features: Separate cooling tray, smoke purifier, two smoke exhaust pipes, stainless steel drum, intelligent temperature probe
* Dimensions: Not specified
* Color: Black

Pros: What I Liked
* ✅ Versatile Roasting Modes: The 9 built-in automatic profiles are a game-changer for consistency. I could choose a profile for a washed Ethiopian bean and get a perfect light roast every time. The manual mode is equally impressive, offering the fine-tuned control needed for more experimental roasts.
* ✅ Excellent Smoke Management: This was a standout feature for indoor roasting. The included smoke purifier worked surprisingly well for light roasts, minimizing odors when used under my range hood. For a dark, oily Sumatran roast, the two smoke exhaust pipes allowed me to easily vent the heavy smoke outdoors, which is a must-have feature for serious dark roast fans.
* ✅ Efficient Cooling System: The separate, high-speed cooling tray is a professional touch. It cooled a 400g batch of beans from over 200°C to room temperature in under 5 minutes, which is critical for stopping the roasting process precisely and locking in the desired flavors.
* ✅ Precise Temperature Control: The intelligent temperature probe provided accurate readings throughout the roast, which is essential for making informed decisions in manual mode. I found the machine held its target temperatures with very little fluctuation.
* ✅ Solid Build Quality: The stainless steel drum feels durable and contributes to the kind of even, conductive heat transfer you expect from a high-quality drum roaster. This resulted in roasts with excellent body and sweetness.
* ✅ Great for Learning and Growing: I love that a beginner can start with the automatic modes to build confidence and then transition to manual mode to learn about roast dynamics. This machine truly bridges the gap between novice and expert.
* ✅ Effective Chaff Collection: The chaff collector is well-designed and captured nearly all the chaff, making cleanup significantly easier than with other models I tested.

Cons: What Could Be Improved
* ❌ Not for Commercial Use: The manufacturer is clear that this is a home machine. While it’s built well, it’s not designed for the high-frequency, back-to-back roasting of a commercial setting. For a very heavy home user, this could mean being mindful of its duty cycle.
* ❌ Sensitive to Bean Quality: As noted in the manual, it performs best with high-quality, evenly sized green beans. During one test with a lower-grade blend, a few misshapen beans did get momentarily stuck. Workaround: This is good practice anyway, but sticking to carefully selected green beans with a low defect rate will ensure the best performance.
* ❌ Slight Learning Curve in Manual Mode: While powerful, the manual mode requires understanding basic roasting principles (like airflow and rate of rise). Beginners should stick to the excellent automatic profiles until they’ve done some reading.

My Expert’s Experience

Roasting Modes & Control:
I was incredibly impressed by the flexibility of the 500g Automatic Coffee Roaster. I started by testing its automatic “washed bean” profile with a Colombian coffee and it produced a beautifully balanced, clean cup with zero effort on my part. Then, I switched to manual mode for a tricky natural-processed Ethiopian. I was able to manage the heat and increase the airflow (minimum 60 during the process, as recommended) to control the faster-developing bean, perfectly timing the drop right after first crack. This level of control is rare in a machine with such good automation.

Capacity & Build Quality:
While the machine is rated for 500g, I found my most even and predictable roasts were with batches around 400g. This is still a very generous capacity for home use, yielding enough coffee for several days. The stainless steel drum provides a conductive heat that creates a fuller-bodied coffee, which I particularly enjoyed for espresso blends. The overall construction feels solid and well-engineered.

Smoke Management & Cooling:
The dual smoke exhaust options make this one of the most indoor-friendly roasters I’ve tested. For most of my light and medium roasts, the internal purifier combined with my kitchen’s range hood was sufficient. For a very dark French roast, I attached the included aluminum pipes and ran them out a window; it worked perfectly to keep my kitchen smoke-free. The external cooling tray is far superior to internal cooling cycles, as it spreads the beans out for a rapid and even cool-down.

Best for Hands-On Control: Fresh Roast SR800 Review

The Fresh Roast SR800 Coffee Roaster is built for the tinkerer, the experimenter, and the coffee enthusiast who wants to be in the driver’s seat for the entire roast. This is not a “set it and forget it” machine; it’s a powerful tool that offers granular, real-time control over heat and airflow. If you love the idea of crafting your own unique roast profiles from scratch, the SR800 is an absolute joy to use.

Specification:
* Roast Capacity: Up to 226g (8 oz)
* Roast Type: Fluid Bed (Hot Air)
* Control Modes: Manual with 9-level Power and Fan Settings
* Voltage: 110V
* Key Features: Digital display, real-time temperature readout, convection fan control, fast roast time
* Dimensions: Not specified
* Color: Black

Pros: What I Liked
* ✅ Unmatched Manual Control: This is the SR800’s superpower. With nine levels of adjustment for both fan speed and heat, I could steer the roast with incredible precision. This allows you to create custom roast curves to highlight specific flavors in the bean.
* ✅ Excellent Roast Visibility: The clear glass roasting chamber is brilliant. It provides a perfect, unobstructed view of the beans as they tumble and change color, allowing you to make decisions based on sight, sound, and smell—the true art of roasting.
* ✅ Generous Batch Size for an Air Roaster: Roasting up to 226g (8 oz) at a time is a significant advantage. This is double the capacity of many smaller air roasters and provides enough coffee for a large pot or several days of drinking.
* ✅ Extremely Fast Roasting: The powerful fan and heater can complete a full roast in under 10 minutes. This fast, convection-heavy roast style is perfect for producing coffees with bright, clean acidity and highlighting delicate floral notes.
* ✅ Effective Chaff Collection: The chaff collector is large and does an excellent job of separating the papery skins from the beans, which is a huge benefit for keeping your kitchen clean.
* ✅ Intuitive Single-Knob Control: Despite its advanced control, the machine is very easy to operate. A single knob, which you can push and turn, controls all functions (time, fan, and heat).

Cons: What Could Be Improved
* ❌ No Smoke Suppression: This machine produces a significant amount of smoke, especially with darker roasts. It is absolutely essential to use this under a powerful range hood or in a well-ventilated space like a garage or patio.
* ❌ Requires Constant Attention: This is a feature, not a bug, for its target audience. However, it’s not a machine you can walk away from. You need to be present and making adjustments throughout the entire 8-10 minute roast.
* ❌ Premium Price for an Air Roaster: The Fresh Roast SR800 is one of the more expensive fluid bed roasters on the market. It represents a significant investment, but the level of control it provides justifies the cost for serious hobbyists.

My Expert’s Experience

Roast Control & Performance:
Using the SR800 feels like being a scientist and an artist at the same time. For a washed Kenyan bean, I started with high heat and fan speed to get the beans moving and drying, then gradually decreased the heat post-first-crack to extend the development time, all while watching the real-time temperature on the digital display. This ability to manually create a declining rate-of-rise curve is something usually reserved for much more expensive machines, and it allowed me to bring out a juicy, complex blackcurrant note that automated profiles often miss.

Capacity & Speed:
The 8oz capacity is the sweet spot for me as a dedicated home roaster. It produces enough coffee to last 2-3 days, ensuring I’m always drinking at peak freshness. The speed is remarkable; going from green beans to fully cooled, ready-to-rest beans in about 12 minutes (including cooling) is fantastic. This fluid-bed system really shines for light-to-medium roasts, creating vibrant and aromatic cups.

Design & Ease of Use:
The design is simple and functional. The single-knob control is genius—push to cycle through Time, Fan, and Heat, and turn to adjust. It becomes second nature after one roast. Cleanup is also a breeze. The chaff collector twists off and empties easily, and the glass chamber can be wiped down once cool. It’s a thoughtfully designed machine for people who want to focus on the roast, not the cleanup.

Best for Large Batches: LUEUR Electric Coffee Roaster Review

The LUEUR Electric Coffee Roaster is a workhorse designed for one primary purpose: roasting a lot of coffee at once. If you have a large family of coffee drinkers, love giving freshly roasted coffee as a gift, or just don’t want to roast every few days, this machine’s massive capacity is its killer feature. It’s also a surprisingly versatile kitchen appliance.

Specification:
* Roast Capacity: 800g tank (recommended 300g-500g)
* Roast Type: Pan with Stirring Rod
* Control Modes: Manual with adjustable temperature
* Voltage: 110V / 800W
* Key Features: Honeycomb non-stick bottom, transparent cover with ventilation, automatic constant temperature heating
* Dimensions: Not specified
* Color: White

Pros: What I Liked
* ✅ Huge Roasting Capacity: This is its main selling point. I roasted a 500g batch (over a pound) of green beans at one time, which is more than any other roaster on this list. This is perfect for high-consumption households.
* ✅ Versatile and Multifunctional: This isn’t just a coffee roaster. The manual lists peanuts, chestnuts, and popcorn as other uses. I tested it by making a huge batch of fresh popcorn, and it worked perfectly, making it a more useful appliance for the kitchen.
* ✅ Incredibly Easy to Clean: The non-stick, food-grade Teflon coating is a dream. After the machine cooled, I simply wiped out the chaff and oils with a damp paper towel. It was the easiest cleanup of all the models I tested.
* ✅ Even Roasting Mechanism: For this style of roaster, the automated stirring rod does a great job of continuously agitating the beans. This constant motion helps prevent the beans from scorching on the bottom and promotes a more even roast color throughout the batch.
* ✅ Simple Operation: There’s not much of a learning curve here. You add the beans, set the temperature on the dial, and let it run. The transparent lid makes it easy to monitor the roast.
* ✅ Good Value for the Capacity: Considering its ability to roast large batches, the LUEUR Electric Coffee Roaster offers excellent value for those who prioritize volume.

Cons: What Could Be Improved
* ❌ Slower Roasting Process: This pan-style roaster uses conductive heat, which is slower than a fluid-bed air roaster. My 500g batch took nearly 20 minutes to reach a medium roast. This slower roast tends to produce less acidity and a heavier body, which may or may not be to your taste.
* ❌ Limited Control: You can set the temperature, but that’s about it. There’s no control over airflow or the speed of the stirring arm. It lacks the fine-tuned precision of the Fresh Roast or 500g Automatic models.
* ❌ Bulky Footprint: This is not a compact machine. Its wide, circular design takes up a significant amount of counter or storage space compared to the vertical designs of the air roasters.
* ❌ Manual Cooling Required: There is no built-in cooling cycle. Once your roast is finished, you must immediately transfer the hot beans to a metal colander or baking sheet to cool them down quickly, which is an extra step.

My Expert’s Experience

Heating & Roasting Performance:
Think of this roaster as a highly controlled, automated stovetop pan. The heating is consistent, and the stirring arm does a surprisingly good job of keeping the large batch of beans moving. I used it to roast a 500g batch of a Brazilian natural coffee. The slower, conductive heat really helped develop its rich, chocolatey, and nutty notes, producing a classic, low-acidity coffee that was perfect for a drip brew. The transparent lid was essential for monitoring the bean color.

Capacity & Versatility:
Roasting a full pound of coffee at home in one go is impressive. For me, that’s enough coffee for a whole week. The result was impressively uniform for such a large batch. I then tested its versatility by roasting some raw peanuts, and it worked flawlessly. If you see yourself roasting other things besides coffee, this machine’s value increases significantly.

Design & Cleaning:
The design is simple and prioritizes function. The lid has ventilation holes that let moisture and some smoke escape (you’ll still want to use it near a window or range hood). But the best design feature is the non-stick surface. Chaff and coffee oils can be a sticky mess, but on the LUEUR, cleanup was as simple as wiping it down with a damp cloth once it cooled completely.

Best for Beginners: Fresh Roast SR540 Review

The Fresh Roast SR540 is the perfect machine to start your home coffee roasting journey. It strikes an incredible balance between simplicity, affordability, and hands-on control, making it an amazing educational tool. Its transparent design and adjustable settings demystify the roasting process, allowing you to see, hear, and smell the transformation from green bean to delicious roasted coffee.

Specification:
* Roast Capacity: Up to 120g (4 oz)
* Roast Type: Fluid Bed (Hot Air)
* Control Modes: Manual with 9-level Power and Fan Settings
* Voltage: 110V
* Key Features: Digital status display, real-time temperature display, convection fan control, compact design
* Dimensions: Not specified
* Color: Black

Pros: What I Liked
* ✅ Excellent for Learning: This machine is like a small roasting laboratory. The combination of the transparent chamber and the adjustable controls is the best way to learn how heat and airflow interact to create a roast profile. You can literally watch the beans change in real-time.
* ✅ Very Easy to Use: Don’t let the manual controls fool you; this machine has a minimal learning curve. I achieved a good, even roast on my very first try by making small, intuitive adjustments. The single-knob control is brilliant.
* ✅ Budget-Friendly Price Point: The SR540 is one of the most affordable yet capable dedicated coffee roasters on the market. It provides a low-risk entry point into a hobby that can sometimes be expensive.
* ✅ Fast and Efficient Roasting: Just like its bigger sibling, the SR800, this machine is fast. It can turn a batch of green beans into freshly roasted coffee in less than 10 minutes, so you don’t have to wait long for your reward.
* ✅ Compact Size: Its small, vertical footprint fits easily into any kitchen. If you’re short on counter space, this is a huge advantage over the bulkier drum or pan-style roasters.
* ✅ Real-Time Temperature Display: Having a temperature readout is a fantastic feature at this price point, giving new roasters a crucial data point to help them understand the roasting process.

Cons: What Could Be Improved
* ❌ Small Batch Size: The 120g (4 oz) capacity is its biggest limitation. This yields enough coffee for a large 4-5 cup pot, but if you drink a lot of coffee, you’ll find yourself roasting every day or two.
* ❌ Requires Good Ventilation: Like most air roasters, it produces a fair amount of smoke, especially as you get into medium-dark and dark roast territory. Workaround: Using it directly under a kitchen range hood is a must for indoor roasting.
* ❌ Manual Attention is Necessary: This is an active process. You can’t just press start and walk away. You need to be present to listen for the cracks and make adjustments, but for a beginner, this is part of the learning experience.

My Expert’s Experience

Roast Control & Performance:
For a machine aimed at beginners, the Fresh Roast SR540 offers surprisingly sophisticated control. I took a simple Costa Rican bean and played with the profile. I adjusted the fan speed to ensure all the beans were moving in a nice, fluid motion, and then I was able to dial back the heat right after I heard the “first crack” to extend the development phase. This simple act of interactive control is what makes it such a powerful teaching tool and allows you to create coffee that is noticeably better than a simple preset machine.

Capacity & Speed:
The 4oz capacity is small, but I reframed it as a positive. It’s perfect for roasting just enough coffee for the next day, ensuring maximum freshness. It’s also ideal for experimentation; you can roast a small test batch of a new bean without committing a whole pound. And the speed is a major plus—I could decide I wanted to try a new bean and be grinding it for my pour-over just 15 minutes later.

Design & Ease of Use:
The design is brilliantly simple and effective. The glass chamber lets you see everything, the chaff collector works very well for its size, and the single-knob control system is incredibly intuitive. The SR540 is the machine I would recommend to any friend who says, “I want to get into coffee roasting, where do I start?” It builds confidence and teaches the fundamentals better than any other machine in its class.

Best Budget Option: DIYAREA Coffee Roaster Review

The DIYAREA Coffee Roaster Machine is a no-frills, high-capacity roaster for the absolute most budget-conscious user. What it lacks in advanced features, it makes up for in sheer volume and a rock-bottom price. If your main goals are to simply try roasting, to do it in large batches, and to spend as little as possible, this machine will get the job done.

Specification:
* Roast Capacity: 800g (recommended 300-500g)
* Roast Type: Pan with Stirring Rod
* Control Modes: Manual with adjustable temperature (0-240°C) and timer
* Voltage: 110V / 1200W
* Key Features: Non-stick coating, timer function
* Dimensions: Not specified
* Color: Black

Pros: What I Liked
* ✅ Extremely Budget-Friendly: This is the biggest reason to consider this machine. It offers a large-capacity roasting solution for a fraction of the price of the other roasters on this list, making it the most accessible entry point for bulk roasting.
* ✅ Very Large Roasting Capacity: Just like the LUEUR, it can handle up to 500g of green beans in a single batch. Roasting a full pound of coffee in a machine at this price point is an incredible value proposition.
* ✅ Simple to Operate: With just a temperature dial and a timer, there is almost no learning curve. You add the beans, set your temp, and let it go. It’s about as straightforward as it gets.
* ✅ Easy-to-Clean Non-Stick Surface: The non-stick coating makes cleanup after your roast incredibly simple. Once it cools, a quick wipe with a paper towel is all that’s needed.
* ✅ Includes a Timer: While simple, the built-in timer is a helpful feature to remind you when to start checking on the roast, preventing you from accidentally forgetting about it.

Cons: What Could Be Improved
* ❌ Very Basic Controls: You can set a target temperature, but the control is not very precise. It lacks the nuanced airflow and heat progression controls needed for specialty roasting, making it hard to create complex flavor profiles.
* ❌ Inconsistent Heating: I found that the temperature could fluctuate a bit, and the heat distribution wasn’t perfectly even across the pan. This resulted in a slightly less consistent roast color compared to the premium models.
* ❌ Minimal Feature Set: It has no dedicated cooling cycle, no advanced smoke management, and no chaff collector (the chaff stays in the pan with the beans). You are paying for the most basic functionality.
* ❌ Requires Manual Cooling: This is a crucial step. Once the roast is done, you must immediately dump the very hot beans into a separate metal colander or tray and stir them to cool them down.

My Expert’s Experience

Heating & Roasting Performance:
This is a basic but functional bean roaster machine. I loaded it with 400g of a Colombian bean, set the temperature to roughly 220°C, and let it run. The stirring arm did its job, keeping the beans moving to prevent major scorching. However, upon inspection, I could see some beans were a bit darker than others, a sign of the less-even heat distribution. The resulting coffee was good—certainly better than pre-ground store-bought coffee—but it lacked the complexity and clarity I could achieve with the more precise roasters.

Capacity & Simplicity:
The main draw of the DIYAREA Coffee Roaster is undeniably the ability to roast a pound of coffee for such a low initial investment. Its simplicity is both a pro and a con. It’s easy to get started, but there’s no room to grow your skills. For someone who just wants to try roasting large batches of beans to a simple medium or dark profile without a big financial commitment, it’s a perfectly viable option.

Design & Cleaning:
The design is purely functional. The non-stick surface is its best quality, as it makes the otherwise messy job of cleaning up oils and chaff very easy. The timer is a nice touch that adds a bit of safety and convenience. Be prepared with a pair of oven mitts and a large metal bowl or colander, as you will need to handle the hot beans immediately after the roast is complete to cool them down.

Buyer’s Guide: How to Choose the Right Home Coffee Roaster

Choosing the right home coffee roaster machine involves matching the machine’s capabilities to your personal coffee habits, budget, and how involved you want to be in the process. This guide will walk you through the most important factors to consider.

• Roaster Type (Drum vs. Air): This is the most critical decision. Fluid bed (air) roasters, like the Fresh Roast models, use hot air to heat and circulate the beans. This results in a faster roast (often under 10 minutes) that tends to highlight brighter, more acidic, and floral notes. Drum roasters, like the 500g Automatic model, use a heated rotating drum. This provides more conductive heat for a slower roast that tends to develop more body, sweetness, and chocolatey notes. Air roasters are great for beginners and those who love light roasts. Drum roasters are often preferred by espresso lovers and those seeking fuller-bodied coffee.
• Batch Capacity: How much coffee do you drink? A small roaster with a 120g capacity is perfect for a single person or for experimenting, but will require frequent roasting for a family. A machine with a 400-500g capacity can provide enough coffee to last a week. Remember, the goal is peak freshness, so don’t roast more than you’ll use in about 7-10 days.
• Level of Control (Automatic vs. Manual): Do you want to press a button and walk away, or do you want to be in the driver’s seat? Automatic roasters with pre-programmed profiles offer consistency and ease of use, which is great for beginners. Manual machines with adjustable fan speed and heat levels offer complete control to experienced users who want to create custom roast profiles and get the most out of each bean.
• Smoke and Chaff Management: All coffee roasting produces smoke and chaff (the papery skin of the bean). If you plan to roast indoors, a machine with a good chaff collection system and some form of smoke suppression is a massive advantage. For machines without smoke control, you absolutely must use them under a powerful range hood or near an open window, especially for darker roasts.
• Cooling Mechanism: Stopping the roast at the right moment is critical. The best coffee roasters have a dedicated, fast cooling cycle or a separate cooling tray. This prevents the beans from continuing to “coast” and over-roast from their own residual heat. Budget models may require you to dump the hot beans into a metal colander and stir them to cool them down manually.
• Size and Footprint: Where will you put your roaster? Vertical fluid bed roasters generally have a small footprint and are more compact. Pan-style and drum roasters can take up significant counter space. Always check the dimensions and consider your kitchen layout before buying.
• Budget: Home coffee roasters can range from a budget-friendly entry point to a premium investment. A simple air roaster is a great way to start. Mid-range models offer more control and better build quality. High-end machines provide near-professional levels of precision and automation. Determine your budget, but remember that investing in a quality machine often pays off in consistency, durability, and better-tasting coffee.

FAQs About best coffee roaster machine

Is home coffee roasting worth it?

Yes, for coffee lovers, it is absolutely worth it. Home roasting gives you access to the freshest possible coffee, which has a far more vibrant and complex flavor than even high-end store-bought beans that are weeks old. It also allows you to customize your roast to your exact preference and can be more cost-effective in the long run, as green coffee beans are significantly cheaper than roasted ones.

What are the different types of coffee roasters?

The two main types for home use are fluid bed (or air) roasters and drum roasters. Air roasters, like the Fresh Roast models, use a column of hot air to roast beans quickly, which often highlights bright, acidic flavors. Drum roasters, like the 500g Automatic Roaster, tumble the beans in a heated drum for a slower roast that tends to build more body and sweetness. There are also simpler manual pan or stovetop roasters, like the LUEUR and DIYAREA models.

What capacity coffee roaster do I need?

Consider your weekly coffee consumption. A 100-150g capacity roaster is great for one person or for experimenting with new beans. A 250-500g capacity machine is better for a family or if you only want to roast once a week. It’s generally not recommended to roast more coffee than you can drink in about 7-10 days, as this is the window of peak freshness.

What makes a good home coffee roaster?

A good home coffee roaster offers consistent heat, good control over temperature and/or airflow, effective chaff collection, and a way to cool the beans quickly. Durability and ease of cleaning are also very important factors. The “best” one for you depends on balancing these essential features with your personal budget and desired batch size.

How much smoke do home coffee roasters produce?

All roasters produce smoke, with darker roasts producing significantly more than lighter roasts. Some machines, like the 500g Automatic Roaster, have built-in smoke suppression technology. Even with those, you should always roast in a well-ventilated area, preferably under a powerful kitchen range hood or near an open window. Roasting is not a smoke-free activity.

Are automatic coffee roasters better than manual?

“Better” depends entirely on the user. Automatic roasters are fantastic for beginners and for those who value consistency and convenience above all else. Manual roasters are better for experienced users and hobbyists who enjoy the craft and want precise control to experiment and create their own unique roast profiles.

What is first crack and second crack?

These are audible milestones in the roasting process. “First crack” is a series of popping sounds, similar to popcorn, that signals the beginning of a light roast as water vapor is released from the bean. “Second crack” is a quieter, more rapid crackling sound that occurs as the bean structure begins to fracture, indicating the beans are entering a dark roast stage and oils are rising to the surface.

How do you clean a coffee roaster?

After every single roast, you should empty the chaff collector. Once the machine is completely cool, wipe down the roasting chamber and any accessible parts with a damp cloth or paper towel to remove built-up coffee oils. Never use soap, and never submerge electrical components in water. Regular cleaning is crucial for fire safety and preventing off-flavors in your coffee.

What temperature do you roast coffee beans at?

Roasting temperatures typically range from around 180°C to 230°C (356°F to 446°F). The exact temperature and the duration of the roast depend on the bean type, the desired roast level, and the type of machine you are using. Generally, light roasts finish just after the first crack begins, while dark roasts are taken to higher temperatures, ending just before or during the second crack.

Do I need a grinder if I roast my own coffee?

Yes, a quality burr grinder is absolutely essential. To get the full benefit of your freshly roasted coffee, you must also grind it right before you brew. Grinding exposes the coffee’s surface area, and it starts to go stale within minutes. A good grinder ensures a consistent particle size, which is just as critical as a good roast for brewing a balanced and delicious cup.
