How to Roast Your Own Coffee Beans in 8 Easy Steps

Table of Contents

Sometimes it’s just more convenient to do things at home. Roasting your coffee beans at home can help you have more control over the flavor of your beans. 

Buying unroasted beans can also help you save a bit of money since you’re doing some of the process yourself.

What You Should Know Before Beginning

To begin with, roasting at home will let you make your coffee just the way you like. It can be a fun hobby, and trying different roasts can expand your coffee horizons. 

Before you just buy some beans online though, you should research the different types of beans to get a scope of just how many different flavors there are in the coffee bean world.

If possible, pick a few small batches of beans so that you can try out multiple types. Once you have your beans, make sure you have a good place to store them. If you buy green beans, you will have around a year to cook them. Just make sure to store them in a sealed container, preferably in a temperature and moisture controlled area of your home.

Finally, roasting coffee beans does create a ton of odor. If you are going to roast them in your kitchen, then be aware of this and open some windows if possible.

Roasting 101

There are four different types of roasts you should be familiar with. Each roast type will affect the overall flavor of your coffee. The first is a light roast, the beans for this roast will be a light brown color and few if any oils will be released from the beans. The second is a medium roast, the beans will be slightly darker in color than the light roast and will only release light oils.

Next, you move on to the medium-dark roast; this roast will have a dark oil, and you will begin to notice more oils being released by the beans. Finally, you have the dark roast, as the name implies the beans will have a dark coloring, and you will notice a significant amount of oil in your water.

Equipment and Coffee Bean Selection

You will need a few different tools in order to properly roast coffee beans. To begin with, get a proper measuring cup and scale for your beans. You will also need a bean roasting tool. The tool will need to handle water temperatures of at least 400 degrees and a bowl for them to cool in.

You should also pick out a tool to stir the beans with. If you plan on using a pot on your stove, know that your beans have a higher chance of burning and will smoke a lot.

As for coffee bean selection, be sure to choose an easy bean to start with and try to create a roast close to the coffee you currently drink. This will help you practice roasting beans and know how close you are getting to making your favorite coffee.
