Brewed a 5gal batch of milk chocolate stout. I thought i mashed at around 152 but found out my thermometer needs calibrating and mashed at about 162. i'm not sure how much unfermentable sugar is in it now. It was the AG kit from austin homebrew and I can't remember the recipe exactly but the website says 10lb base grains, 3.13 lb specialty grains 1lb lactose. The SG is stuck at 1.042 and i'm not sure how low i'm going to get. OG was 1.082 Pitched Danstar windsor. That should bring me down to about 5%abv or so. Did the lactose really make that big of a deal, my mash temp, or both? I've been in the primary for a month.
