Finding The Right Coffee Roaster For You
You might have made a pick out of our selection of coffee roasters, but it doesn’t end there.
It might sound intimidating at first, but roasting your own coffee is an art, and it will take some skill to get it right, especially with your first few roasts. As with everything else in life, practice makes perfect, so give it some time, and you’ll maybe end up as a coffee roastmaster!
Some factors look out for, like the size, tools, and roasting method in a home roaster. Coffee can be fickle during the process but using a good machine is a wise investment if you want to take roasting seriously.
Coffee beans roast fast too, so using the wrong tool or machine, your roasts can end up lacking flavor or, worse still, lead to chargrilled roasts.
Don’t worry. We won’t leave you out in the dark. We’ve got some tips for you for your roasting journey listed right below.
Why Popcorn Poppers Aren’t Ideal For Roasting Coffee Beans
Roasting coffee beans with a popcorn popper is indeed possible. But, as we mentioned above, it isn’t the best way to roast, especially if you’re using good quality green beans and like different kinds of roasts.
This type of equipment is specifically designed for corn kernels, which are smaller than your average-sized beans. You will struggle to obtain an even distribution of heat for your roast coffee, which can lead to inconsistencies in your roasted beans.
Choosing the right popcorn popper can be a struggle too. Some machines are underpowered, so they can’t reach the temperatures needed. They are also not used to maintaining hot temperatures for a longer duration, which can strain the motor leading to more breakages.
Popcorn poppers have smaller chambers compared to your home coffee roaster too. This can be a problem if you’re looking for a machine for big batch roasts.
This is not to say that a popcorn popper is a lousy way to go if you want to dip your toes in the coffee roasts. You can use it as a stepping stone to learning all the roasting basics, but if you’re looking to get serious in your endeavors, a dedicated machine is still the way to go (not just anything though, it needs to be worthwhile).
Different Home Roasters For Coffee
A key part of roasting is high temperature, and there are different methods used mostly because of the size of the batch. The beans undergo a chemical change called the Maillard Reaction due to the heat.
In a nutshell, this chemical reaction is a significant factor in giving coffee its aroma and flavors. Most coffee roasters use indirect heat in roasting the flavor-packed coffee, but they differ in how they do it.
Hot-air coffee roasters are faster than other methods, and it can lead to a “purer” cup because of its convection process. The green coffee beans are placed on a tilted bed where heated air is circulated throughout the coffee and blows out any impurities. However, they can only roast small batches, and you cannot accurately inspect your on-going roast.
Drum roasters use conduction to roast beans by spinning the beans around in a heated chamber. You can roast bigger batches of coffee with a drum machine and be used with different heat sources. It has a longer roast time, and the machine is bulkier compared to other methods.
Conduction coffee roasters utilize direct contact with heat, and drum roasters use this method too. Pan roasters also use conduction, and they are considered more portable and energy-efficient compared to their counterparts. They are prone to burn, and you can only roast small quantities peruse.
Roasted Coffee Batch Size
One thing to consider in getting your own home coffee roaster is how many beans you’ll be roasting for your use. As mentioned above, drum roasters can allow for bigger batches. If you prefer drinking one type of coffee per week or month, a drum roaster might be perfect for you.
Hot-air coffee roasters are smaller and roast fewer green coffee per batch than your standard drum roaster. If you’re the type to drink a different single-origin or blend every few days, a hot-air coffee roaster is recommended.
The bigger the batch you’ll want to roast, the bigger the machine you’ll need, so you’ll have to consider if the roaster has enough space in your home.
Being precise is one of the significant factors in coffee, whether you’re brewing or roasting. Each measurement can make the difference between a bad or a good cup of joe. If you’re looking for a home coffee roaster that you’ll only need to flip a switch and let it all do the work, there are options, but they will cost more.
The more you spend, the more extras will come with the roaster, which will offer more control over the coffee roasting process. Some can adjust the time, temperature, airflow, and even the rotation speeds in the case of a drum roaster.
Temperature is a significant factor in roasting, and there are roasters with a thermocouple which offer the best control. These are roasters with a digital thermometer and temperature control. Roasting off aroma and just giving it a go isn’t going to provide you with the best results. You can also adjust when your beans will hit the first crack or second during the process through heat control.
Higher-end roasters are programmable, meaning you can find what you enjoy and save it for future use. It can save a lot of headaches if you tend to switch coffee between batches for varying roasts.
