PSA: I just read that coffee beans can lose about 60% of their aroma within 15 minutes of grinding

Found that stat in an old roaster's guidebook I picked up at a flea market in Seattle. Does anyone else have a specific time window they try to brew within after grinding?

My record is brewing yesterday's forgotten grounds, so you're doing fine.

Wow, 15 minutes? My morning routine is basically me grinding beans, then getting distracted by my cat for a half hour. So I'm probably brewing with sad, aroma-free dust. What's the longest you've let grounds sit before realizing your mistake?

Read somewhere that the aroma loss slows down after the first 15 minutes, so you're not doomed if you forget for a bit. I've definitely left grounds sitting for like 20 minutes and the coffee still tasted fine to me.
