Roast date

The roast date is the information on the bag that tells you exactly when the green coffee beans left the roaster. In the specialty coffee world, freshness is key because right after roasting, coffee naturally releases carbon dioxide and slowly loses its volatile aromas. The best flavor, full of unique tasting notes, is usually achieved between two weeks and about three months from this date. It is actually a good idea to let the beans rest for a few days before brewing to allow this degassing process to calm down. Interestingly, coffee does not spoil overnight like milk, it simply starts to taste flatter and more like cardboard as time goes on.
