How to Freeze Coffee Beans
Freezing halts staling and can keep beans fresh for months. The trick is portioning into airtight bags and never thawing/re-freezing, which causes condensation and staleness.

Does freezing coffee beans actually work?
Yes - freezing is one of the best ways to slow staling, but only if done right. Coffee beans degrade from oxygen, moisture, heat, and time. Airtight freezing stops all four. The key is: portion beans into airtight bags before freezing, do not freeze and refreeze, and do not open the bag until the beans reach room temperature (otherwise condensation forms on the cold beans).
Freeze a two-week supply per bag. Take out what you need, let it sit sealed for 1-2 hours before grinding. Do not refrigerate - condensation and fridge odors ruin beans. For espresso, frozen beans grind slightly finer and pull shots with less channeling, because cold beans are more brittle. Frozen beans stay fresh for 1-3 months.
