I realise this might make me a coffee wanker philistine but I grind a day or twos worth of coffee and pour it from my grinder caddy to a small sealable tupperware pot. This doesn’t spill anything, and it’s then easier to fill my Aeropress from that pot using the provided scoop, again without spilling. The grinds aren’t always ultra fresh, but it does make life a bit easier…
Once made the ground get popped into the food bin and then I wash off the crumbs leftover on the Aeropress into the sink.
