Description

Decaf is short for decaffeinated coffee. It's coffee from coffee beans that have had at least 97% of their caffeine removed. Caffeine can also be removed using carbon dioxide or a charcoal filter — a method known as the Swiss Water Process. The beans are decaffeinated before they're roasted and ground.
Does decaf coffee taste different from regular coffee? No, decaf coffee doesn't taste different much different from regular coffee. The slightly more sour notes you can find in the coffee are a side issue from how it's is processed, but more on this later.
