To save money and flavour, I got myself a grain mill. I thought this would be simple, but setting the grind/crush size seems to be even more difficult than in the world of coffee 🙈

So far I’ve learned that AIOs like my Brewzilla (Gen 4) like the crush a little coarser because the grain basket and overall construction restrict the flow of the wort already. Can anyone here confirm or refute that? Does anybody have that exact same system and care to share their preferred setting (or settings/tendencies, as different malts can be milled to different sizes)?

    I use a Braumeister, and grind size is a bit of an issue. Too coarse - bad efficiency. Too fine - dough. My recommendation would be to check what Brezilla recommends. Braumeister has a recommended size on their website. And use that as a starting point. Go a bit finer if efficiency is still bad. Try the size on the Braumeister website if Brewzilla does not have any. I grind at my local homebrew shop and their mill says ‘7’ ish.

    Also, even if AIO, during the mash I usually stop 2-3 times and open up the malt pipe and give it a good stir. Improves efficiency for my setup.

    Also, true, for smaller grains like rye or specialty black grains, do grind them separately, and way finer to make sure they don’t slip by.
