Coffee roasting is the process of turning coffee beans into the delicious, roasted coffee that we all know and love. It’s a complex process that involves a lot of different variables, all of which can affect the final product. Coffee beans are heated to extreme temperatures during roasting, eliminating the harmful microorganisms that may be present in uncooked coffee.
However, if you understand the basics of coffee roasting, you can produce some amazing coffee at home. In this guide, we’re going to cover everything you need to know about coffee roasting, from the different types of roasts to the equipment you’ll need.
So, let’s get started!
The Different Types of Roasts:
There are four main types of coffee roasts: light, medium, dark, and extra dark.
Light Roast:
Light roasts are typically lighter in color and have a more delicate flavor. The beans are roasted for a shorter period of time, which results in a coffee with more acidity.
Medium Roast:
Medium roasts are typically darker in color and have a more balanced flavor. The beans are roasted for a longer period of time, which results in a coffee with less acidity.
Dark Roast:
Dark roasts are typically very dark in color and have a bolder flavor. The beans are roasted for an extended period of time, which results in a coffee with less acidity.
Extra Dark Roast:
Extra dark roasts are typically black in color and have a very bold flavor. The beans are roasted for an extended period of time, which results in a coffee with almost no acidity.
The roast color is not a good enough guide to tell you everything about the coffee. It’s better to use your senses of smell and taste to guide you. Except the main ones, there are endless roast variations.
The most important thing to remember is that there is no right or wrong when it comes to coffee roasting. It’s all about personal preference. So, experiment with different roasts and find the one that you like best!
