Just tried a grass fed brisket yesterday, 3.5lbs, put Jeff's rub on it , brought it to room temp and smoked at 200-215 for almost 7 hours. It was very dry but tasty. The internal temp was 165 wehen I put it in a pan with au jus and covered, leaving it in the smoker til internal temp reached 203. Did I do something wrong? Do these leaner pieces need to go higher internally?
