The duration and temperature of roasting can vary depending on the desired roast level, which ranges from light to dark.

The best time to roast coffee is right before you plan to brew it. Coffee is at its peak flavor within a few days of roasting, so it’s recommended to roast small batches frequently to ensure freshness. However, if you prefer to have a supply of roasted beans on hand, you can store them in airtight containers away from light and heat to preserve their flavor for a couple of weeks.

Where Can You Roast Coffee?

You can roast coffee beans in various settings, depending on the equipment you have. Some people prefer roasting outdoors to avoid smoke and odor indoors, while others choose to roast in their kitchen using specialized home roasting machines. Regardless of the location, make sure the roasting area is well-ventilated and free from any flammable materials.

Why Roast Your Own Coffee?

Roasting your own coffee offers several advantages. Firstly, you have full control over the roast level, allowing you to tailor the flavor profile to your taste preferences. Secondly, freshly roasted coffee is more flavorful and aromatic compared to pre-roasted beans. Lastly, home roasting can be a cost-effective option in the long run, as green coffee beans are generally less expensive than roasted beans.
