Freeze Coffee Before Or After Resting?

Want to talk espresso but not sure which forum? If so, this is the right one.

Hi All,

Just picked up two pounds of freshly-roasted espresso blend from my favorite local roaster. I know I need to let it rest a day or two before using it, but what about the portion I will vacuum-pack and freeze?

Last pound I bought I divided in half and froze one half right away. When it came out of the freezer a week or so later (I went though the first half pound much faster than I'd expected), the bag wasn't quite as vacuum-packed as it had been, and blew up like a balloon upon reaching room temperature.

So: Let it all rest a couple days, then freeze part of it, or freeze part of it right away?

Short answer: rest first

From what I've seen, usually you would rest espresso roasts longer than a couple of days... conventional wisdom seems to be something in the order of 2 weeks after roast. Some say that vacuum sealing adds a couple of days of age, so if I was looking to vac seal for espresso I would probably vac seal around 10 days after roast and then freeze straight away.

Most "espresso" roasts seem to do well 1-2 or maybe 3 weeks after roast, so I'd freeze reasonably soon after you get them.

Medium-light and lighter roasts often benefit from 2-4 weeks of rest when destined for the espresso machine. There, I freeze when they're "ready". For the high-end, European rosters, for me, I freeze when the next month's subscription ships.
