Longer developing time also causes dough to become more acidic. Up to a point, this is a a good thing. More acidity in bread means it stays fresher longer, and lactic and acetic acids add valuable and unique flavors, aromas, and sensations. However, too much acidity creates a cloying aftertaste that many people, including me, find disagreeable. The trick is finding the right balance between time and temperature so the dough develops a desirable complexity of flavors without becoming too acid or dominated by alcohols, while simultaneously getting optimal development of the structure of the dough.
My SD would stay fresh for a very long time compared to the loaves I bought from a local bakery however mine also had a very strong aftertaste and now I know why. I've got some dough in the proofer now. I've been closely watching the rising times and temps along the way keeping it conservative whereas before I would usually go to the end of the recommended range. It will go into the fridge tonight and get baked tomorrow. Hopefully this time I will not end up with that strong aftertaste.
