Hello homebrewers. I'm hoping for some help and hopefully the answers here this will help everyone out. Attenuation. I have done around 7 batches of all grain brewing with only 2 row base malts, and I can't achieve above 63% attenuation. I have read Gregg Doss's "Exploring Attenuation" and have tried to follow this as a guide.
Milling my grains at 0.7mm with a two roller mill. Recently started doing two millings of the grain (didn't work).
Getting the temperature to 153*F with a mash from 60 to 75 minutes.
I have used pH stabilizer (star san).
I've used small amounts of CaCl and CaCO3 (after the mash). I've tried using spring water. Tap water
Boil is around 60min give or take a few minutes.
In many of the batches I've added 0.2 oz of Williamette hops.
Pitching about half of 11.5g packet (so 5.75g of yeast) of Safale US-05 (supposed to get 78-82% attenuation).
e.g. recent batch was at 1.087 O.G and I've received a 1.032 F.G after a week and a day or fermenting. I did this batch on the stove top.
Having said all this my most recent batch had a mash that ranged from 145.4*F to 153.1*F. When the temp dipped I would put the heat on low and stir to get the temp up. I'm at a loss here guys and I'm not sure how to get a better attenuation.
