Home coffee roasting is a growing trend among coffee enthusiasts. Not only can home roasting be a fun hobby, but it also offers a number of advantages over purchasing coffee from your favourite roastery.
- Green coffee beans cost less than beans that are already roasted.
- Green coffee beans have long shelf life and stay fresh a lot longer than roast coffee beans, so you can purchase them in larger quantities.
- The lower cost allows you to explore a wide range of coffees that you might not normally be able to afford.
- You can create your perfect blend by choosing how dark the roast is and where the beans are from.
What to Look for in a Home Coffee Roaster
Whether you are new to coffee roasting or are looking to upgrade your current roaster, there are a few important factors to keep in mind when trying to find the best home coffee roaster
Most home coffee roasters are either a drum or fluid-air bed design. Drum roasters use a rotating chamber along with ambient and contact heat to roast and agitate the beans. With fluid-air roasters, a fan floats the beans on a bed of forced air.
Fluid-air bed machines roast coffee at a higher temperature than drum machines. This produces coffee with a brighter and more complex flavour. Beans that are drum roasted tend to produce a slightly sweet coffee that has more depth and body. As a general rule, drum roasters produce a more consistent dark roast than fluid-air machines, so they are typically preferred when roasting espresso.
The size of the fan in a fluid-air bed roaster limits the amount of beans that you can roast at any given time. Most fluid-air bed machines can hold between 2.5 and 5 ounces beans, whereas, most drum roasters have a larger capacity and will hold up to 10 ounces of beans per roast.
Always remember that roasted coffee beans taste at their freshest and thus best up to 5 days after roasting. Anything beyond that and they start to lose some of their subtle aromas. Depending on your preferred coffee strength, 2.5 ounces of beans will yield up to two 10-cup pots of coffee after roasting. By keeping this ratio in mind, you can extrapolate the appropriate roaster capacity for your needs.
Ease of Operation
Home coffee roasting machines run the gamut from hand-operated and low-tech to highly sophisticated with automated temperature, roast level, and cooling options. The simplest options require you to monitor the roasting process much more closely; however, they are significantly less confusing and intimidating for the novice roaster.

- Step 4: Once the beans are already inside, the chamber’s lid should be closed correctly. If not, the roaster might start malfunctioning or might need a repair sooner than you expect.
- Step 5: After the chamber’s lid is closed, you may now put the roaster’s chamber back into its original place. The chamber must be placed properly inside the roaster. If not, this might affect the performance of the roaster or might cause damage to the roaster.

- Step 11: Wait until the cooling is done. Cooling is done once you get to hear a distinct tone.
- Step 12: Detach the chamber from the unit. Use oven mittens when you do that.

What’s more, you are also allowed to experience other users’ recipes and share yours with them as well via the sharing app.
- Step 2: After selecting a recipe, pour the green beans into the Doser. Make sure you do not exceed the 60-gram limit each time. Take note that the 60g beans can produce about 50g coffee.
- Step 3: Allow the roaster to start working. The roasting can last up to 3 minutes or up to 10 minutes. The roasting time depends on the recipe that you choose.
- Step 4: Observe how the colour of the beans changes from the original green colour, the colour of the beans gradually changes to a pale shade to yellow to tan or orange to a lighter shade of brown to a darker shade of brown.
- Step 5: As soon as you hear the initial crack, the beans can already produce a lighter roast coffee during this time. So, you either stop roasting or continue until you hear the next crack.
- Step 6: If you wish to continue roasting, expect the second crack. This is the last crack, and it signals the end of roasting. The color of the beans has now turned to a darker shade of brown. You cannot roast much further after this because you will only get burnt beans.
- Step 7: Remove the container that contains the chaff, and place a clean container to gather all the roasted beans. This procedure takes away the heat from the roasted beans as fast as possible.

The pan is constructed of aluminum, and the clip-on lid has a wooden handle that you crank to stir the beans. You do have to rely on your senses of sight, smell, and hearing to know when your coffee has reached the appropriate level.
The Whirley-Pop is an old-fashioned style roaster that does not require any electricity. You only need a source of heat and a bit of effort to turn the handle crank.
No products found.
You should only roast one-half to three-quarters of a cup of beans at a time to avoid damaging the gear teeth.

The Whirley-Pop is probably the least expensive way to try your hand at roasting coffee. It is portable and will allow you to roast coffee even without electricity. The simple construction of the Whirley-Pop makes cleanup a breeze.
Adding too much coffee to the Whirley-Pop can damage or break the gears. You do need to take the roasted beans outside to remove the chaff to avoid making a mess in your kitchen.

The FreshRoast allows for on-the-fly adjustments of temperature and fan speed so that you can achieve virtually any level of roast. The controls are intuitive, so the learning curve is minimal.
The fan does not always do a good job of agitating the beans, especially at the beginning of the roasting cycle. You may have to do some manual stirring in order to achieve an even roast.
The beans are cooled in the roasting chamber, so you need to anticipate some carry-over roasting. This means that you may need to manually stop the roasting cycle before the beans reach the desired roast level to ensure that they do not end up too dark.
This machine does not have a smoke suppression feature, so you need to make sure that you have plenty of ventilation when roasting.

Roasting is not a difficult task at all when you use Behmor 5400 1600 Plus due to its user-friendly features and functions. Below is a basic guide that you can use while roasting coffee beans using this roaster.
- Step 1: Set aside the unit’s chaff tray and roasting drum.
- Step 2: For starters, drop ¼ lb coffee beans into the drum.
- Step 3: Preheat the coffee roaster. Preheating should not exceed the 1:45-minute limit. If you preheat further than the limit, this can hinder the roasting process.
- Step 4: After preheating, hit the OFF button. After which, put the chaff tray and the drum inside the roaster. Be sure to use a pair of oven mittens while placing the tray and the drum to prevent your skin from getting directly in contact with the hot roaster.
- Step 5: Choose the profile you like. You have 5 options to choose from. Your user’s manual have all the specifications for each profile, so it is necessary that you check out your user’s manual before roasting any coffee beans. In addition, the roasting duration will depend on the amount of beans and profile that you pick.
- Step 6: Watch out for the initial crack. The initial crack shows that the green beans have turned into light brown beans. Actually, you may end the roasting process during this time, which depends on your preference and the type of beans you use. However, if you prefer to roast further, wait another minute or a minute and a half more before you hear the second crack. Again, the interval between the initial crack and the next crack will vary according to the type of beans or amount of beans that you use.
- Step 7: Prepare for the next crack. The next crack signals that the roasting process has reached its maximum point, and it is at this stage that your beans have been roasted further. When you finally hear the next crack, hit the COOL button at once. From the moment you hear the next crack, you should be able to hit the COOL button within ten seconds.
- Step 8: Allow time for cooling. Cooling time will take about 2 minutes.
- Step 9: Once the cooling time is completed, it is safe to stop using the roaster. Also, you are now ready to clean the roaster before you put it away.

Should you buy a drum roaster or an air roaster? Are expensive roasters better than cheap ones? Which coffee roasters are the easiest to use? How do you roast coffee beans? These are all good questions, read on to find the answers.
Drum Roasters vs. Air Roasters
They work differently. The coffee beans in drum roasters are roasted through indirect heat, while the coffee beans in air roasters are roasted through direct heat.
A drum roaster can actually handle more quantities than the air roaster type. Drum roasters have chambers that are specially designed to have more room for bigger quantities of beans. On the other hand, air roasters only offer a limited space that can usually accommodate contents that are only good for up to two persons. So, if you are not a heavy coffee drinker, a standard air roaster is ideal for you. However, if you often prepare coffee not only for yourself but also for the other members of the family, a regular drum roaster will be great.
Drum roasters do not work fast, so you will have to wait long before you can see the results. The drum roasters can finish the roasting process between fourteen to twenty minutes. Thus, if you are always in a hurry, you will only be disappointed when you use this equipment. On the contrary, air roasters are ideal for busy people since they can finish roasting only between eight to twelve minutes.
Speaking of drum roasters, they cost more than air roasters. Although their price is higher, you can expect the drum roasters to last longer as their durability is more reliable compared to that of the air roasters. Besides, their size is not only bigger but they can also be used for commercial purposes.
Speaking of air roasters, they make an affordable option. What’s more, when you are just beginning to learn how to roast coffee beans, air roasters can be the best bet. In addition, air roasters are more suitable for personal use.

What’s more, you can drink as much as you like without breaking your budget as home coffee roasting is an affordable option.
Sourcing your coffee beans
Before roasting the beans for your homemade coffee, you should know something more about the coffee beans, such as where to buy green coffee beans, what type of beans to buy and other related ideas. You can actually get green coffee beans from many places. You can buy green coffee beans locally from the nearest local shops that you can find in your area.
If you are considering how to roast coffee commercially, you can get from wholesalers as they can certainly provide you with whatever amount of coffee beans you wish to buy since they sell raw coffee beans wholesale. However, if you are only buying for your personal use or for the family, there are coffee beans sold at supermarkets or retail outlets. Finally, you can also buy green coffee beans online. It’s really good since online shops sell different varieties of coffee beans such as the best coffee beans 2015. They also sell various amounts of coffee beans such as bulk coffee.
Furthermore, you definitely want your coffee to have a great taste, so you want to get the best coffee beans in the world. To get the best beans, make sure that the beans have great flavours like the Arabica beans, must be fresh, organic and smooth to your taste buds.
Now that you know where you can get coffee beans and the basic characteristics of the best coffee beans to buy, you will be more prepared to learn coffee roasting in the easiest way possible. Below are simple coffee roasting 101 steps that you can follow anytime, anywhere.
- Step 1: Prepare your space
- Step 2: Ready everything you need for roasting
- Step 3: Start using the pan
- Step 4: Start roasting the coffee beans
- Step 5: Watch as the coffee bean colour transforms
- Step 6: Observe the 1st crack
- Step 7: Expect to hear the 2nd crack
- Step 8: Transfer the coffee beans
- Step 9: Allow some hours for degassing
Step 1: Prepare your space
You must remember that smoke is inevitable when roasting coffee beans. That is why it is a good idea to open every window at home and use the fan while roasting. Roasting in open spaces like at your back porch is quite an ideal spot if you especially do not want the smoke inside your home.
Step 2: Ready everything you need for roasting
Learning how to roast coffee beans at home is easy provided you have all the things you need. Check if you already have the following:
- Spatula (pick the wooden kind)
- Colander (choose the metal type)
- Oven gloves
- Stove Burner
- Green coffee beans
Step 3: Start using the pan
The pan should be preheated first and foremost before you roast the beans. If you ask exactly at what temperature to roast coffee, the temperature is actually based on the stove you use; however, the preheating can be approximately 500 degrees Fahrenheit.
Step 4: Start roasting the coffee beans
Once the pan gets hot, it is the best time to pour some coffee beans into it. Use the spatula to stir the coffee beans. The stirring must be done gently. Stir in such a way that the coffee beans are evenly roasted.
See to it that you buy green coffee beans for roasting which you can consume only for about a week to ensure freshness. Unless you are using the coffee beans for a lot of people, you are not supposed to buy bulk green coffee beans as you might not be able to consume them all in a short time or you might not like the taste of the coffee beans after roasting.
Step 5: Watch as the coffee bean color transforms
It is important to note the difference in coffee roasts colors during the roasting process. The green beans change color, from the original shade of green to the new shade of yellow to various shades of brown. You will know that the process is done when you see a darker shade of brown. This can be observed between eight to ten minutes.
Step 6: Observe the 1st crack
If you really want to learn the technique on how to roast coffee well, watch out for the initial crack. You should wait patiently to hear the initial crack as this is your key to making sure your coffee beans are roasted well since this will give you a signal that the color of the beans has already changed into a lighter shade of brown, which means that the roasting process is almost done. In fact, at this time, the coffee beans are acceptable for cooling if you prefer that way.
Step 7: Expect to hear the 2nd crack
If you are not satisfied with the lighter shade of brown, you may wait for a few more minutes until you get to hear the 2nd crack since it signals the end of the roasting process. At this stage, you can expect to see the color of the coffee beans has become a darker shade of brown, which is ripe for cooling. As soon as you hear the 2nd crack, don’t wait too long; instead, remove the pan from the burner right after a few seconds. This is one of the important coffee roasting tips that you should take note of.
Step 8: Transfer the coffee beans
As soon as you remove the pan from the burner, the coffee beans will start to cool. You should transfer the coffee beans to a colander. It is easy to separate the chaff from the beans when you use a colander. Place the colander in an open space so that cooling does not take that long.
Step 9: Allow some hours for degassing
The duration time for degassing varies, from several hours to a couple of days. After which, you may already try your first homemade coffee!
Indeed, it will certainly be as easy as pie to learn how to roast coffee as long as you have all the supplies for roasting and follow the steps mentioned above. What’s even more interesting is that you can definitely prepare your own coffee whenever you crave for it now that you know how to roast green coffee beans.
A Word of Warning About Home Roasting
Coffee roasting requires high temperatures, which can be dangerous. It is important to use proper safety precautions and to never leave your roaster unattended.
• You should always follow the safety instructions for your machine
• Use appropriate safety gear to avoid burns
• Only use your roaster in a well-ventilated area
If you are just starting to explore home roasting, I would suggest the Nuvo Eco or Whirley-Pop roasters. While they do not give you the precision roast of a more expensive roaster, they will allow you to produce decent home-roasted coffee with minimal expense. If you find that you are serious about your roasting hobby, you can consider spending money to upgrade to a high-tech roaster.
For the avid home coffee roaster, I would recommend the Gene Café. It is the most expensive roaster on this list, but its unique drum rotation and precision dial controls produce results equal to what you might find in a commercial roastery.
