5 benefits from coil folds in the sourdough bread making process. * Strengthen the gluten network. As you lift the dough and let the ends tuck underneath, the gluten strands become more organized and better able to hold their shape. * Improve gas retention. A stronger gluten network traps more of the CO₂ produced by fermentation, which can give you better oven spring and a lighter, airier crumb. * They’re gentle. Compared with aggressive kneading or even some stretch-and-fold techniques, coil folds strengthen the dough while preserving developing gas bubbles. * Help higher-hydration doughs. This is where coil folds really shine. Wet dough can start out loose and puddle-like; successive coil folds help it become smoother, stronger and more self-supporting. * Give you feedback about your dough. Early in bulk, the dough may stretch dramatically when you lift it. As strength develops, you’ll notice that it lifts more like one cohesive, jiggly mass and releases from the container more cleanly. Coil folds vs. stretch-and-folds Neither is automatically “better.” I often think of stretch-and-folds as stronger early strength-building and coil folds as gentler strength-building later in bulk. For example, you might do 1–2 sets of stretch-and-folds early, followed by 2–3 sets of coil folds about 20–30 minutes apart. You don’t necessarily need to keep folding just because a recipe says so—if your dough has become smooth, elastic and holds its shape well, more folds aren’t always better.
