Would increase water to 1.75 qt/lb for sach rest followed by enough sparge water to cover grain bed by at least 2 inches. Possibly there's not enough water to rinse the grains.
How big is your mash tun? What is the depth of water that covers the grain during the sach rest? What is the before and after temperature for the sach rest?
Apparently I've been missed by HBT forum so might as well return post here.
Haven't measured the effects of stirring (or not stirring) before run off but when in doubt - stir. That said - still knocking out upper 80s % extraction efficiency thanks to tips from Mr. Denny. Was able to "coax" the...
Thanks again Denny. I remembered to fully open the faucet whilst draining the wort after sach rest and didn't get a stuck drain when mashing an OG of 1.095. :rockin:
I got stuck sparges on previous batches with high OG.
I read Palmer's book and a couple months later brewed all grain using 5 gallon round cooler and 5 gallon boil kettle. It's not difficult if you are systematic and pay attention. By the way, I never brewed before and went all grain 1st time out.
Go for it. :)
Yes more sparge water would increase extraction but already at max volume for boil kettle. Even with a larger kettle the added boil time would make for quite a long brew day which isn't something I would like to do regularly.
Thanks to Denny (primarily) all grain extraction efficiency has improved to 85+% consistently. Since the improvement past brews have been 1.075 or less OG. Recently brewing batches with OG 1.090+ extraction efficiency has dropped to 80-85%. Mash equipment consists of 5 gallon round cooler and...
Made a IIPA using almost 10 lbs of grain mashed in a 5 gallon igloo circular cooler. Got an 87% extraction vs the regular 90%. Think an upgraded wooden mash paddle over the flimsy plastic one would have helped stirring here. Might try a small braid vs the cpvc manifold since there seems to...
