Pat the beef completely dry before seasoning. Any surface moisture will steam instead of sear, and you’ll lose the crust that makes this dish. Work in batches and give the pan time to recover heat between them. A crowded, steaming pan is the most common reason a braise falls short of the best version of itself.
Use something you’d actually drink — a Chianti Classico, a Barbera d’Asti, even a solid table red. It doesn’t need to be expensive, but it shouldn’t be unpleasant on its own. Cheap “cooking wine” with added salt and preservatives will muddy the braise. One glass for the pot, one glass for the cook.
Like every braise, this stew is noticeably better the next day. Between the chuck’s natural collagen and the three packets of gelatin stirred into the broth, the braising liquid sets up almost like an aspic overnight in the fridge — cold, jiggly, and nearly firm enough to hold its shape. (Aspic is just a savory stock set firm with gelatin, classically used in French kitchens to hold meats or vegetables in a clear, glossy jelly — that same concentrated gelatin is exactly what gives this stew its rich body.) Reheat gently on the stovetop over low heat with a splash of broth if needed, and it melts right back into a silk-textured gravy, deeper than it was the day before.
