Espresso Roast - Espresso & Coffee Machines
Strength and flavor of an espresso greatly depends on roast level. Unroasted green coffee beans contain all coffee's acids, proteins and caffeine but they can not be used for preparing traditional coffee and espresso beverages because they do not contain coffee's characteristic flavor, aroma and color. To achieve that green coffee beans must be roasted.
There are several different roasting levels which determine coffee's color flavor and strength, usually divided into five roast categories:
- Cinnamon Roast (also called Half-City Roast, New England Roast and Institutional Roast) - green coffee beans are roasted until they become tan and began to pop for about 8-9 minutes
- Regular Roast (also called American Roast, British Roast and Medium Roast) - green coffee beans are roasted until they become medium brown for about 10-11 minutes
- Full City Roast (also called High City Roast and Special Roast) - green coffee beans are roasted until becoming chestnut brown colored for 11 to 15 minutes
- Continental Roast (also called Dark Roast, High Roast and Double Roast) - green coffee beans are roasted until they become very dark brown colored from 15 to 18 minutes
- Espresso Roast or French Roast - green coffee beans are roasted until becoming very dark, almost black for 18 to 20 minutes
For preparing espresso is traditionally used the espresso roast with low acidity but with rich bittersweet flavor, however, any other roast level coffee beans can be used to make an authentic espresso. The choice of roast level varies greatly from country to country as well as from personal taste.
