DIY Coffee Roasting at Home: A Complete Guide from Beginner to Expert

Coffee is an essential drink for many people every morning, and roasting your own coffee beans can bring you a more fresh and personalized taste. Although it is convenient to buy ready-made roasted coffee beans in the store, roasting them yourself not only allows you to master the whole process, but also adjust the taste and flavor according to your own preferences. This article will provide you with a detailed guide to teach you how to DIY roast coffee beans at home.

Preparation

Before we get started, we need to prepare some basic tools and materials. The first thing is to choose the right green beans. There are a variety of green beans from different origins, varieties, and processing methods available on the market. It is recommended that beginners choose some green beans that are easy to handle and easy to get feedback information (such as color changes).

In addition, you will need a few basic pieces of equipment: an electric or manual rocker-type hot air claw, a precision scale, a thermometer, a roasting jar, and a cooler. These can be purchased at specialty coffee supply stores or online.

Step 1: Preheat

First, preheat your hot air claw machine to the proper temperature. Different types of beans require different temperatures, usually between 180°C and 230°C. Use a thermometer to make sure you've reached the correct temperature.

Step 2: Weigh the beans

Use a precision scale to weigh the appropriate amount of green beans. Generally speaking, it is recommended to control the amount of green beans to about 200 grams each time for better control of the whole process.

Step 3: Start baking

Pour the green beans into the preheated roasting tin and close the lid quickly to prevent a lot of rich flavor from being lost when the coffee carbonizes.

Observing the color change is one of the most important indicators to judge whether the coffee is done. At the beginning, the coffee will become yellow and emit a herbal smell; over time, it will gradually turn brown and begin to emit a delicious aroma. When the coffee beans turn into the color you like, you can start cooling them.

Step 4: Cooling

Pour the roasted coffee beans into the cooler and shake it quickly to speed up the cooling process. This step is very important because if the temperature is not reduced in time, the coffee will continue to roast and may result in over-roasting.

Preserve and taste

Once completely cooled, you can store the roasted coffee beans in an airtight container. It is best to taste them again after 24 hours for the best taste and flavor.

Of course, DIY roasting at home is also a process of continuous learning and improvement. By adjusting parameters such as time, temperature and ratio, you can make a variety of different flavors of coffee according to your preferences.

Summarize

DIY roasting coffee beans at home is a fun and challenging activity. As you gain experience, you will be able to master more techniques and make coffee that suits your taste preferences. I hope the guide provided in this article can help you start your own roasting journey!
