The Difference Between Medium and Light Roasts

The Difference Between Medium and Light Roasts

Coffee is a popular beverage, and the degree of roasting of coffee beans has an important impact on the taste and flavor of coffee. Medium roast and light roast are two common roasting methods, which differ in time, temperature and flavor.

1. Baking time

Medium roasting usually takes a long time to complete, generally about 10 to 15 minutes. This allows the coffee beans to be fully exposed to high temperatures, resulting in more chemical reactions. In contrast, light roasting only takes 5 to 8 minutes to complete.

2. Furnace temperature control

Medium oven temperatures are usually controlled between 210°C and 220°C. This temperature range allows the coffee beans to reach the proper internal processing level and maintain a certain moisture content. Light oven temperatures are lower, usually between 180°C and 205°C.

3. Taste characteristics

Medium heat brings rich flavor and taste to coffee. During the roasting process, the acidity inside the coffee beans will be reduced to a certain extent, while retaining some of the characteristics of the original coffee beans. The coffee produced by this roasting method usually has a balanced, full and soft taste.

In contrast, light roasting focuses more on the flavor of the original coffee beans themselves. Due to the lower temperature and shorter time, light roasting can retain more of the unique floral and fruity aromas and bright and refreshing acidity in the original coffee beans.

4. Caffeine Content

There is also a difference in caffeine content between medium and light roasts. Since medium roasts take longer to process, some of the chemicals may be broken down or converted into other substances, resulting in less caffeine in the final product.

Conversely, operating the oven at a light fire can reduce this conversion process and allow the final product to retain a higher level of caffeine.

5. Applicable scenarios

Medium roasted coffee beans are suitable for making various types of coffee, including espresso, Americano, cappuccino, etc. This roasting method can maintain the richness of flavor while also making the acidity and bitterness relatively balanced.

The light color fire is more suitable for single-origin brewing or hand brewing. It can highlight the special flavor brought by the original beans, and usually has a higher acidity and refreshing feeling.

in conclusion

Medium roasting and light roasting are two different roasting methods. They differ in time, temperature, taste, and applicable scenarios. Choosing a roasting method depends on personal taste preferences and what kind of flavor characteristics you like to experience. Whether it is medium roasting or light roasting, you can choose the coffee that best suits your taste needs according to your preferences.
