Liguid sour starter

2014 'dan beri

I started my bakery by using a sourdough starter, i currently add this sour starter to give a richest flavor to my bread, i sell my bread with sourdough as an ingredient and i add yeast to make it faster on my daily production. When i wish to bake a long fermentation and nutricious bread i just take out the yeast from the recipe and give a longet time on rising by controlling the tempeture.
