Preground coffee is lighter and simpler but stales faster; vacuum-sealed doses help. A tiny hand grinder offers freshness and control but costs grams and time. Test both on shakedown hikes to learn tolerance for effort, noise, and chilly fingers at dawn.
Coffee scent draws critters. Double-bag grounds and used filters in odor-resistant pouches, and store with all smellables in approved containers or hangs. Keep mugs, presses, and cloths out of tents, and never dry coffee-soaked materials where breezes push aroma toward water or camps.
