I know the answer is in here somewhere but I am too tired to search anymore, lol. I have made several all grain beer with poor efficiency. my last batch was my own little twist with an ipa. 12lbs of 2 row pale, 1 lb of caramel malt and 1 lb of roasted barley. i set up the mash and batch sparge for a preboil volume of 6.5 gallons. i am calculating my efficiency at 54%. i am mashing in the low to mid 150s. i typically and very close to 150, but this last batch was more like 155. i did my mashout and sparge water at 175. i am stirring with mashout and sparge water. i have watched numerous videos on youtube and have read several more websites. so here i am turning to an excellent source i should have asked a long time ago. tips, tricks or otherwise at improving efficiency is much appreciated.
