And it went pretty darn well! BIAB in the Igloo cooler, was shooting for 153 at mash in, was just under 154, 151.9 after 60 minutes. Can only do a 4 gal. boil and after the initial running and the batch sparge, I ended up just a pint under 4 gal. Took a gravity reading, 1.042, and according to tasty brew, I ended up with a 78.7 mash efficiency. Now we will see what it tastes like. It's the first batch I've made in about 7 years so in pretty pumped. Thanks to everybody on here for all the info!
