The three most common roast levels are light, medium, and dark. The roast level affects the flavor and aroma of the coffee. Choose a roast level based on your personal preference, and experiment with different levels to find your favorite.

How Long Does The Roasting Process Take, And How Do I Know When The Beans Are Done?

The roasting process typically takes between 10-20 minutes, depending on the desired roast level. You can tell when the beans are done by listening for the "first crack" and "second crack" sounds, and by monitoring the color of the beans.

How Should I Store My Home-roasted Coffee Beans?

Store your beans in a cool, dry place, away from light, moisture, and air. Use airtight storage containers made of glass or ceramic, and try to use your beans within 2-3 weeks of roasting for optimal freshness.
