If you prefer a stronger sourdough taste to your sourdough bread, there are a few ways to do this. One is to feed your starter less frequently to make it more acidic in flavor. Another is to let your sourdough bread dough rise longer. This works well during cooler months when you can let it rise for up to 14 hours. During warmer months, let it rise in the fridge for up to 8 hours, then room temperature for 6-8 hours.
