One question I receive most often goes like: \u201cHow do I control the sourness in my bread?\u201d Some bakers want an assertive, mouth-puckering tang that makes sourdough, well, sour<\/em>. Others prefer a milder, more nuanced acidity that lingers in the background (I\u2019m usually in this camp). Thankfully, sourness is something you can control at nearly every stage of the breadmaking process to dial in your loaves just how you want \u2019em.<\/p>\n

Over years of baking, I\u2019ve come to understand that the \u201csour\u201d in sourdough is really the result of a conversation between time, temperature, and the microorganisms living in your starter. Once you understand how these factors interact, you can push your bread in whichever direction you prefer.<\/p>\n

Now that I\u2019ve written and codified this guide, I look back on my baking over the past decade and realize I\u2019ve kind of made these decisions instinctively to alter my bread\u2019s flavor profile. If you\u2019re a frequent reader here, you\u2019ll see the same themes running throughout (e.g., young, fast levain for mild flavor; super-ripe levain and more whole-grains for more sourness, etc.).<\/p>\n

In this guide, I\u2019ll share what I\u2019ve learned, both from the science side and from the countless loaves I\u2019ve baked in my own kitchen, to help you adjust the sourness of your sourdough bread. <\/p>\n

Keep in mind that there are many ways to increase\/decrease sourness, and these are the steps I use in my baking.<\/strong><\/p>\n

To Increase Sourness<\/th>\nTo Decrease Sourness<\/th>\n<\/tr>\n<\/thead>\n
Use starter past its peak ripeness (collapsed, strong sour aroma, loose consistency, frothy)<\/td>\nUse starter\/levain at peak ripeness (risen, mild sour aroma, some small bubbles)<\/td>\n<\/tr>\n
Extend cold proof (24-48+ hours)<\/td>\nShorten cold proof (10-12 hours) or skip it<\/td>\n<\/tr>\n
Use a stiff levain (50-65% hydration)<\/td>\nUse a liquid levain (100% hydration)<\/td>\n<\/tr>\n
Ferment warmer for more total acid (78-82\u00b0F)<\/td>\nFerment cooler and shorter for less total acid<\/td>\n<\/tr>\n
Increase whole grain percentage (especially rye)<\/td>\nUse more white flour<\/td>\n<\/tr>\n
Let levain ripen longer<\/td>\nUse a young levain<\/td>\n<\/tr>\n
Use a smaller levain (10-15% pre-fermented flour)<\/td>\nUse a larger levain (25-35% pre-fermented flour)<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/figure>\n

Now, let me explain why these adjustments work and share what I\u2019ve learned about the fascinating science happening inside your dough.<\/p>\n
