Hi all, Recently got into brewing and am really enjoying it. However I'm keen to get my quality and consistency up to better justify the days spent in the garage. My first big concern (of quite a few) I'd like to sort is my terrible mash efficiency. Any pointers would be much appreciated. I'm using a pretty basic set up but I'd hoped I'd be able to get good results anyway. It's a Peco boiler with a grain bag from thehomebrewcompany.co.uk I got a grain kit from the same firm and it came crushed, does anyone have any experience of them and if that's crushed enough to use in BIAB? This brewday was for a stout recipe (2.5kg pale, 0.5kg oats, 0.5kg wheat, 0.25kg choc, 0.25kg roasted barley, 0.25 Munich) and I started with 26L of water. I'm getting the water up to about mash temp and then adding the grain. Yesterday I wanted to mash at 63.5C so I got the water to 65 and added the grain, doing so in three goes with a big stir between each. I mashed for 80 mins and stirred quite aggressively every 15 minutes. I tried to squeeze the bag quite a bit afterwards but have heard mixed messages about this. After I left the bag in a tub to drain I did see it had quite a bit left absorbed so I wonder if it's worth going the extra mile on the squeeze or maybe even dunk sparging and allowing for a bit longer on the boil to compensate? I took a sample pre-boil and measured a SG of 1.034 which looks like an efficiency of just under 55%. At the end of the day I got about 4 gallons off into fermenters with an OG of 1.044 so I'm happy I'll get something drinkable (the last batch was tasty but a little watery) but I was hoping for a much bigger beer than this. Any help, critiques, tips or mockery are very welcome.
