🥖 Sourdough Starter Hydration Explained: 100%, 75%, and More
Introduction
If you’ve been exploring the world of sourdough, you’ve probably heard terms like “100% hydration” or “low hydration starter” tossed around like secret baker’s code. And if you’re thinking, What on earth does that mean?, don’t worry—you’re not alone!
Hydration levels might sound technical, but they’re really simple to understand. And trust me, once you get the hang of it, you’ll feel like a total pro. Let’s break it down together so you can keep your starter happy, healthy, and ready to rise beautifully every time.
What Is Hydration in Sourdough?
Hydration refers to the ratio of water to flour in your sourdough starter, measured by weight (never by volume!). This ratio affects how thick or runny your starter is, how fast it ferments, and even the final flavor of your bread.
📏 Common Hydration Levels Explained:
- 100% Hydration: Equal parts flour and water by weight. (Most popular and easiest to maintain—perfect for beginners!)
- 75% Hydration: Thicker starter; ferments slower and gives a milder flavor.
- 125%+ Hydration: Runny starter; ferments faster and creates a tangier, more open crumb.
Why Does Hydration Matter?
- Fermentation Speed: Higher hydration = faster fermentation.
- Flavor Profile: Thicker, low-hydration starters produce milder flavors; higher hydration brings out tanginess.
- Ease of Use: 100% hydration starters are easier to mix, feed, and measure—ideal for both new and seasoned bakers!
If you’re just starting out, I always recommend sticking to 100% hydration—it’s simple, predictable, and works with almost every recipe.
How to Maintain 100% Hydration (The Easy Way)
- Grab a digital kitchen scale (it’s a baker’s best friend!).
- Feed your starter with equal weights of flour and water. (30g of Starter)
- Example: 100g flour + 100g water.
- Mix until smooth and thick like pancake batter.
- Keep it in a warm spot and watch it come to life!
