This is my second brisket and I was worried she w/b ready at 8 this am how quickly the internal temp shot up during the first 3hours.. Man was I wrong. She has been hanging between 155 - 162 for the last 5 hours or so. It actually went up to 161 then back down to 150s before starting to climb again. Grate has been around 220 although now it is at 250. This is an 11.5# partial trimmed choice brisket from my local butcher. Can't wait for Mothers Day dinner!! Will post pics later.
