You'll see two cuts at the store: the flat (leaner, uniform thickness, easier to slice) and the whole packer (flat + point, more forgiving because the fatty point bastes everything). It's typically recommended that for your first brisket you should go with a packer, the extra fat gives you some forgiveness. When picking out a brisket, look for good flexibility: pick it up in the middle and if it bends easily, the meat is probably well-marbled. USDA Choice is the sweet spot for value; Prime is better but often 50% more. To process, trim the fat cap down to about ¼ inch before cooking. Any thicker and it won't render well, any thinner and the meat dries out.
Brisket is a patience game, not a skill game. If you can maintain a steady 225–275°F for half a day, you can make a great brisket. The biggest mistake people make is pulling it off the heat too early. This is a cut where you want to forget the clock; a 12-pound brisket might take 10 hours or 16 hours depending on the individual piece, your cooker, and the weather. The only reliable doneness test is the probe: when a thermometer slides into the thickest part like it's warm butter, it's done. Below you'll find times for smoking, oven roasting, slow cooker, and Instant Pot.
Brisket needs 195–205°F for tender, sliceable meat. At 145°F (USDA minimum for beef) it would be safe but completely inedible. Brisket is a tough cut full of collagen that only breaks down above 180°F. The 12+ hour cook time at 225–275°F makes food safety a non-issue and you usually pass this 140° mark in the first couple of hours. The probe test is more useful than a temp reading: when a thermometer slides in like butter, it's done.
