Hey Everyone!
I'm going on my 10th all grain batch or so and I can't seem to hit efficiency levels higher than 65% to 66%. I've adjusted multiple things over the batches and none have seemed to make a difference. Here's what I'm doing:
My preboil and post boil gravities are constantly low and I always adjust the readings for temperature. Any ideas? I've been adding a couple of pounds of base grain for each batch to make up for it, but I'd rather pinpoint the root cause and fix it instead of just throwing a bunch of extra grain into the mix.
Thanks!
Dave
I'm going on my 10th all grain batch or so and I can't seem to hit efficiency levels higher than 65% to 66%. I've adjusted multiple things over the batches and none have seemed to make a difference. Here's what I'm doing:
- 3-tier brew system all gravity fed with a 10 gallon orange cylindrical cooler with stainless braid manifold for mash tun.
- Use Beersmith to calculate measurements - I sparge using batches that fill 75% of mash tun volume, sparge using equal size batches and drain mash tun before starting batch sparge
- I use the pre-detremined batch sparge mash profiles in Beersmith so I'm usually mashing between 150 and 156 degrees for an hour
- Sparge water temp of 175 degrees
- Grains pre-milled from Austin Homebrew Supply
