Question: 1 / 400

How long does the freshness of ground coffee beans typically last?

1 day

30 minutes

Ground coffee beans typically maintain their optimal freshness for about 30 minutes after being freshly ground. This is due to the increased surface area exposed to air, which accelerates the process of oxidation and staleness. After grinding, coffee quickly loses flavor and aromatic qualities because volatile compounds dissipate rapidly.

For this reason, when brewing coffee, it is generally recommended to grind the beans just before extraction to ensure the best taste and aroma. The other options indicate durations that either underestimate or overestimate the freshness of ground coffee, which may lead to a less satisfying coffee experience if relied upon for longer storage or waiting times.
