For my coffee stuff, I typically make Aeropress ($40) with a metal filter for the lady and use the OXO pour over ($18) for myself.

I like manual brewing so I can regulate all the ratios and temps to my liking. It isn't as fun to do both of those right after waking up though, so I make them at night into mason jars. Now I got a jar sealer attachment for my vacuum sealer ($10) and the coffee stays dang near at original quality until morning, so I just pop the top and have nice chilled pour over every morning. They make standalone jar sealers for cheap, but I have a spendier tabletop unit to do bags and jars.

I seal the beans in vacuum sealer containers as well now and they seem to be maintaining potency longer. I'm on week 3 of the current bag, and it still smells almost brand new every time I open it compared to my old airtight but not vacuumed container. The special jars are pretty cheap or a pound of beans should fit in a 32 oz mason jar.

So if you've already done the basics, think about checking out vacuum sealing. I use it for bunches of things. Pre-chopped veg for recipes (diced onion in 1/2 onion portions, 2 chopped celery and 2 chopped carrots for soup/stew, etc), wild game, make big batches of long cooked tomato sauces so we can have weekend meals during the week, resealing chips, cookies, and crackers so they don't get stale. All kinds of stuff.

So I make cold brew in large batches (week supply at a time). I've struggled to find a burr grinder that can get me a consistent coarse grind in large enough quantity.

Do y'all have a recommendation for one that can help with this?
