1. Fresh Roast SR540 – Best home coffee roaster for beginners

best home coffee roaster

The Fresh Roast SR540, the successor of the SR500, is the perfect tool for those who are new to roasting beans with anything else than a popcorn popper. It is easy to use and understand intuitive controls and simple but sturdy design.

Most coffee connoisseurs would suggest starting with the FreshRoast SR540 as it provides decent control over the roasting process. With this small coffee roaster, you can roast 4oz (or 120 grams) of beans at a time. That is more than enough for a few cups and will last you a few days. It has a real-time temperature display. However, since the temperature is measured where it enters the chamber, it might slightly vary the actual temperature within the chamber. If you want to be completely precise, you should use an infrared thermometer for that.

The fan provides a constant and throughout movement of hot air between the beans. It also makes them tumble around the chamber for an even roast. It operates on the fluid bed roaster principle. 


  • Great control over the timer, fan, and temperature. 
  • Quiet enough so that you can hear the cracking of the beans. 
  • 3 minutes cooling stage – works like a charm.
  • Simple enough for anyone new to roasting to pick up this art.


  • The chaff collector does not always collect all of the chaff.
  •  On the lower settings, the fan is too weak, the lowest you can go is on setting 3 for it to be efficient, but that is enough for a good roast.

2. Gene Cafe CBR-101Home Coffee roaster for knowers and professionals

Gene Cafe CBR-101 best home roaster

One of the best home coffee roasters that are capable of roasting larger batches of beans of up to 8oz. The Gene cafe coffee roaster offers great control over the roasting process. Its 3D off-axis drum rotation system provides an even and throughout roast to all the beans while decreasing the overall roasting time down to around 15 minutes per full batch. One of its best qualities is the quietness with which it operates. Meaning you can safely use it in your house without troubling your family and neighbors. It also has a smoke reduction system in place for your darker roasts.

The temperature and time controls can be adjusted before and during the roasting providing you with great adjustability over the process. The chaff collector is large and highly effective in collecting all the chaff from the drum. 

The best part yet – you can see the beans clear;y during the process. So you do not need to trust that your time and temperature settings are correct (even if they are impeccable). You can see the beans at all times and just hit the stop butting when you see that they have reached the perfect roast level.

Overall, this is the best small coffee roaster for home use for both – those new to this and those who have had some practice already. Although this coffee maker stops short at the higher end of the price tag, it is well worth it, much like the Apple products.

Why should you roast coffee at home?

I know that you know that coffee starts losing its aroma as soon as the roasting process is finished and the beans come out of the coffee roaster. Even though I have told many times before that nothing tastes better than coffee brewed using whole coffee beans that you grind yourself – something can taste better. 

The beans that are roasted before packed, although done with the best coffee roaster machines, start to lose the aroma and freshness right after you take them out of the roaster. Meaning – you will never get the ultimate cup of coffee unless you roast and grind the beans yourself. 

That is where the home coffee roaster comes in. Nowadays you can buy a good home coffee roaster machine for a decent price and start roasting the beans yourself. There are small coffee roasters that will fit easily on your countertop or in your motorhome if you like to travel much and use gas stoves or burners. And larger roasters that you can plug-in electricity. 

Coffee roasting can be fine art, it can also turn disastrous

You can become a true coffee guru by learning more about the process of how a green coffee bean from a field somewhere in Colombia or Brazil ended up in your house. Learning about the process of coffee roasting and the differences between roasting degrees can be fun, and a great conversation starter anywhere you go (especially in coffee shops).

And what is even better – you can adjust the taste to your preferences. You can experiment with blends, origins, roasting types, and degrees. The possibilities are endless, and you can learn about it your whole life. 

So, I have you convinced of the coffee roasting benefits at home? The roasting of coffee really does sound great, but how to go about it? There are several factors you need to consider before buying your own coffee roaster. 

Types of coffee roasters – the first thing you need to learn

There are two types of coffee roasters. Not only when roasting coffee at home, but also when roasting coffee commercially. Air and drum roasters. The air roasters are generally considered as a small batch coffee roaster with fewer beans being roasted at a time. Air roasters can usually do a portion for one of two people at a time.

Whereas drum roasters are used in industrialized processes as this type of roasting can roast larger batches of beans at a time. Most people prefer air roasters over drum roasters for home use as home drum coffee roasters, tho smaller, takes longer to roast the beans than the air roaster. The reason for that is that there is something artistic to using the air roaster, you have to find the perfect balance between the heat temperature, the roasting time and the bean profile. Only then you will have the best roast, it is hard to achieve, but once you have done it, the joy and proud is immense. 

Air roasters

Air roasters use heated air to roast the beans, the beans do not touch the surface of the container, thus avoiding the burning. Instead, they are tumbling around pushed by the heated air. These roasters do the job more quickly, and the best coffee roaster models give the user a lot of control over the roasting profile, allowing to adjust the roast to your preferences. 

Drum roasters

Drum roasters work more slowly than air roasters. But they will be able to roast larger batches of beans at a time. It depends on the size of the roaster you have, but these machines will produce about 8 to 12 oz of coffee beans from one batch. As it is with the air roasters – the more you pay for the roaster the more control over the roasting process you’ll have. 

Electric roasters or stovetop?

Then you have another choice to make – whether to go for a roaster that is simple and basic to use – one that goes on top of an open fire or a stove. Or to go for a more complex machine that will use either a gas burner or will be plugged into an electricity socket. For a personal coffee roaster, you can go both ways. But before deciding think of how you are going to use your coffee roaster. 

Stovetop roaster

A roaster that is meant for a stovetop will be perfect if you are looking for an inexpensive, portable coffee roaster for your beans. The most popular choice in this category would be the ceramic coffee roaster. One of the most popular choices here is the Nuvo Eco Ceramic Handy Coffee Bean Roaster. However, with these roasters, you will need to pay more attention to listen for when the beans start to crack and they need constant attention. You will need to shake the roaster by hand quite often to stir the beans around, otherwise, they would get burnt. 

Electric roaster

An electric roaster is gaining popularity between home coffee roasters because of the ease of use, convenience and the level of control they offer. One of the most visible roasters in this category is the Fresh Roast SR540. Most famous for its ease of use and diversity, it can only roast 4oz or 120 grams of coffee beans at a time, but it comes with a wide variety of various settings. 

Coffee roaster capacity

Air roasters are smaller and drum roasters are larger and can roast larger quantities. 

Usually, it is enough with a capacity of 8oz. (250 grams) to roast enough beans for a few people that would last for a week or so. It is a good idea to figure out how much coffee you consume in a week, for example, and then see which roaster capacity you would need. Larger coffee roasters are available, too, for example, 1 lb coffee roaster, which would amount to holding about 450 grams of coffee, but those are more industrialized and costs way more (not to mention that you don’t really need a roaster with that capacity at home). A small coffee roaster is better. 

Controlling the roast

How much control do you need? Is it enough just to flick the switch, set the timer and go brew a cup of coffee (time and temperature control) while you are waiting for your beans to roast? Or do you want to have full control over the roasting process? Including creating and saving roasting profiles and preferences for increased consistency or roast over longer time periods? The basic rasters will offer you only the roasting time control. Whereas more expensive equipment can provide you with time, temperature, condition, various regimes, smoke suppression and more. The more money you are ready to spend on the roaster, the more control you get. However, I would suggest starting small. Buy something basic to see how you do, once you have learned what to look for and how to roast, you can upgrade. 

Cooling the beans

This process is as important as the roasting itself. In industrial coffee bean roasters, one of the most important aspects is cooling. Once the desired level of roast has been achieved, the beans are then transferred to a special tray and cooled down as quickly as possible. Roasting of beans is a fine art that requires high precision to get the best result. If the cooling process is not immediate and efficient, the beans will continue roasting, exceeding the ideal roast time. 

It is the same story with home coffee roasters. Although it is not that important when doing it at home for small-batch coffee roasters as you can always do more experimenting. 

What is the cooling process?

So, when buying a home coffee roaster find out what is the proposed cooling process for your roaster. Some of the roasters will use cool air to cool the beans down. More expensive roasters will have special, separate trays where the beans will go, to have them cooled down much quicker.  

Cold air cooling means that cold air will be blown over the beans once the roasting is finished. This is a not-so-effective way, as the heat is not dispersed quickly enough. 

Special tray involves the beans being dropped in a special tray outside the roaster where they are cooled down much quicker. 

Ease of use and Cleaning your roaster

Lucky for us, home roasters are very easy to use, most of them are a one-button operated roasters where you don t have that much control over the roasting process. Usually, you will only get to manipulate the time and temperature of the roaster. And you don’t really need much more as those are the two main variables for any roast. For commercial roasters, you have much larger control, including the level of moisture, pressure and so on.  

How easy is it to clean the roaster?

Easy, they are not very complicated and a wet cloth after each roasting session will be enough.  Every now and then you will need to bring it in for annual service – where it gets opened up, cleaned properly and checked the roasters’ overall status.  

What about the smoke? When roasting, some roasters will have smoke reduction systems in place, but even with those, when roasting darker beans, there will be a lot of smoke. Consider this when you buy the roaster – perhaps you will not be able to keep it in your kitchen? Spend a little more to have a smoke reduction system.

Is it noisy?

Some of the roasters can get quite loud during the roasting, look for the models that are quiet if that is important, one of the more quiet brands is the Gene Cafe CBR-101 Home Coffee roaster, but there are others, too. Check the specifications and cons and pros lists for the roaster you intend to buy. 


What are the roast types?

There are four standard roast types. Light, medium, medium-dark and dark. In contrary to what most people think, the most caffein is not in the dark roast coffee beans, but in the light and medium-light roast. 

Light roast – roasted in the temperature between 350°F and 400°F, at this temperature the beans will not reach the first crack and will gain a light brown color. 

Medium roast – roasted in the temperature between 400°F and 430°F, in the roasting process they will acquire a darker-brown color and will be less acidic. 

Medium-dark roast – roasted in the temperature between 435°F and 445°F. Here the beans are roasted until right after the second crack. 

Dark roast – roasted in the temperature between 465°F and 480°F.

How long do coffee beans need to Degas?

This is important to know! When coffee is roasted, there are various gasses forming within the beans. Most of it is carbon dioxide. The degassing process can take somewhere from 2 days to 3 weeks, depending on the coffee itself. Darker roasters will take less time for this process than lighter roasts.

What you need to know regarding the degassing process is that you should not use the coffee beans right after roasting is finished. First of all – too much carbon dioxide will ruin the taste of the coffee, you have to let it bloom for at least 12 hours before using it. For most coffee types the optimal resting time would be around 2 days, sometimes more. 

When can I drink coffee after roasting?

After the roasting, you should always let the coffee beans breathe for a while, in most cases 24 hours would be enough. During this time the beans will release most of the CO2 that builds up during the roasting process and the coffee will taste better. 

How long do roasted coffee beans last?

Remember to always roast just enough beans to use them in a short period. After the beans are roasted it is best to use them within a week, then just buy or roast another batch. You can keep the beans for up to 10 days, but more than that and they will start to lose the aroma and will become stale and not tasty.

Final words

When you are interested in coffee more than just getting the first cup in the morning from your local coffee store. When you think about coffee brewing as a form of art, which it is. You start to notice how many things there are to learn. First, you need to master various coffee brewing techniques (there are quite a few). Then you realize that maybe, just maybe, buying pre-ground coffee beans from the shop is not your style anymore (there is nothing wrong with that tho, those beans are great). And you would like to invest in some good coffee grinders, as you realize that you are losing some of the freshness by buying the pre-ground coffee.

Once you get the hang of brewing, grinding the coffee beans, the next logical step is to start roasting them, too. It takes practice, patience, and will bring the best results from your failures along the way. Nevertheless – there is nothing better than the smell of freshly roasted coffee beans early in the morning, or late into the night. Need an inspirational story?

Coffee marks an excellent start of the day, enjoy it!
