Tried a whole wheat sourdough bread today, it turned out awesome! I used 1/2 all purpose & 1/2 wholewheat flour. We had to control ourselves otherwise we would have eaten it all.

I am a beginner sourdough baker and self taught off the internet so not sure what is necessary in my sourdough baking steps. After I mix my dough and let it rest, I have always done 2 or 3 stretch and folds. I noticed in your sourdough videos @Sandra Brenes you go right into shaping after dough has risen 4 or so hours. Is stretch & folds necessary? Thanks!

Here's a video explaining what happens at 4, 6, 8, 12, 24, 36 & 72 hours in the fermentation process. How long do you ferment your dough?
