What is roast date in coffee?

Roast date is the date on which a coffee was roasted, printed on the bag or packaging. It's one of the most important pieces of information for a coffee consumer or home brewer - more useful than a "best before" date, which tells you relatively little about where in its freshness window a coffee currently sits.

For roasted coffee, freshness matters. Immediately after roasting, beans are actively degassing CO₂ and are typically too fresh to brew well - particularly for espresso. Most roasters recommend a rest of at least 5-7 days for filter brewing and 10-14 days for espresso before the coffee is at its best. After that, a well-packaged roasted coffee typically performs well for 4-6 weeks, with quality declining noticeably beyond that.

For home roasters buying green coffee from GCC, roast date takes on additional significance - you control it. Roasting in small batches means you can align roast date precisely with your intended brew window, ensuring you're always working with coffee at peak freshness. This is one of the defining advantages of home roasting over buying pre-roasted: complete control over the freshness timeline from roast to cup.
