Bulk fermentation has now started, and this is when I take the temperature of my dough. Sourdough Journey has a very helpful table on temperature and percent rise.
My dough is usually anywhere from 70-75 degrees which means I’ll do a 50% rise.
NOTE: I like using a large measuring cup because it makes figuring out the percent rise so much easier.
The dough starts at 2 ½ cups and I need roughly a 50% rise so when the dough is at 3 ¾ cups it will be ready to shape.
NOTE: For consistent results I really recommend using the Sourdough Journey’s chart, He has created a very helpful chart that covers different temperatures of dough, the percentage rise, and an ESTIMATED time it will take. This has helped a tremendous amount in getting my bulk fermentation just right. Which you know is one of the hardest parts of sourdough!
During the start of the bulk fermentation complete 4 coil folds each 30 minutes apart.
I complete the coil fold method by placing slightly damp hands under the center of the loaf and lifting it up. I then turn the container a quarter turn and repeat this until the dough starts to tighten and no longer stretches very far. Make sure you are not tearing the dough.
Then let your dough rise on the counter until it reaches that needed rise. Remember this will vary based on the temperature of the dough. Warmer dough needs less of a rise than cooler dough.
After you have reached your desired rise on your sourdough bread dough. Now it is time to shape the dough.
