# Sourdough Hydration: What Percentage to Use

The ideal sourdough hydration ranges from 75-85%, with 80% being the sweet spot for most bakers. This means for every 100g of flour, you'd use 75-85g of water. Higher hydration (80-90%) creates open crumb structure and chewiness, while lower hydration (70-75%) produces denser loaves. Your choice depends on flour type, environment, and desired texture. Beginners often start at 75% and adjust based on results.

🌊 What Exactly Is Sourdough Hydration?

Hydration is the ratio of water to flour in your dough, expressed as a percentage. If you're using 500g of flour and 400g of water, that's 80% hydration. It sounds technical, but it's really just a simple math formula that transforms your baking game.

Think of hydration like the personality of your sourdough—it determines everything from how the dough handles to what your final loaf looks and tastes like. A wetter dough (higher hydration) behaves differently than a stiffer one, kind of like how different people have completely different vibes at a party.

• Hydration percentage = (water weight ÷ flour weight) × 100
• Most sourdough falls between 70-90% hydration
• Home bakers typically use 75-85% for best results
• Professional bakers often work with 85-95% for open crumb

🎯 Why Does Hydration Matter for Sourdough?

Hydration affects nearly every aspect of your baking experience. It influences gluten development, fermentation speed, crust crispness, and that gorgeous open crumb structure everyone chases on Instagram.

A well-hydrated dough creates the coveted irregular holes that make sourdough Instagram-famous. It also develops better flavor because the longer fermentation (which higher hydration naturally encourages) allows wild yeast and bacteria to do their magic. The starches break down more completely, creating complex flavors you simply can't rush.

🍞 How Does Higher Hydration Change Your Loaf?

When you increase hydration to 80-90%, you're looking at:

• More open crumb structure with larger, irregular holes
• Crispier, crunchier crust
• Chewier interior texture
• Better flavor development from extended fermentation
• Wetter, stickier dough that's harder to handle

Higher hydration doughs require more technique and confidence. They're like a spirited kitten—full of potential but demanding patience and skill to manage properly.

🥖 What About Lower Hydration?

Lower hydration (70-75%) gives you:

• Denser, tighter crumb with smaller holes
• Easier dough to handle and shape
• Sturdier, less delicate loaves
• Perfect for sandwich bread or beginners
• Faster fermentation times

If you're just starting your sourdough journey, lower hydration is your friend. It's forgiving, manageable, and still produces delicious bread.

📊 Recommended Hydration Percentages by Goal

• Beginner baker: 70-75% hydration
• Intermediate, open crumb: 78-82% hydration
• Advanced, maximum openness: 85-90% hydration
• Sandwich bread: 70-75% hydration
• High-altitude baking: 75-80% hydration
• Humid climates: Start at 75%, reduce if needed

🧂 Does Salt or Starter Affect Hydration Percentages?

Your salt and starter percentages don't change your hydration calculation—hydration is strictly flour and water. However, they do affect how your dough behaves at that hydration level.

Salt strengthens gluten and slows fermentation, making higher-hydration doughs slightly easier to handle. Your starter's consistency (liquid versus stiff) should stay consistent for predictable results, but it doesn't factor into the hydration math.

🔧 Essential Tools for Sourdough Success

Accurate measurement is crucial for hydration success. Here are some excellent tools:

• Hario V60 Scale (ASIN: B08D7P7QKX) - $50-60 on Amazon. A precision scale perfect for measuring flour and water to the gram.
• Etekcity Food Scale (ASIN: B077T6Y5LD) - $25-35. Budget-friendly and surprisingly accurate for home baking.
• OXO Good Grips Measuring Cups (ASIN: B00006JPGC) - $10-15. For those preferring volume (though weight is more accurate).
• Dutch Oven Le Creuset (ASIN: B00CMS9FXC) - $200-350. Creates steam for that perfect crust. Worth the investment.
• Banneton Proofing Basket (ASIN: B09CPZFPQT) - $15-25. Keeps your high-hydration dough in shape during final proof.

💡 Pro Tips for Hydration Success

Start at 75% if you're new to sourdough. This gives you room to increase hydration once you understand how your specific flour, climate, and starter behave. Different flours absorb water differently—all-purpose flour absorbs less than whole wheat or bread flour.

Keep notes. Seriously. Track your hydration percentage, fermentation times, room temperature, and results. After a few bakes, you'll notice patterns that help you adjust for success.

Trust the process over the timeline. Rather than baking "when the timer says so," look for signs: the dough should pass the poke test, show visible bubbles, and increase about 50% in volume during bulk fermentation.

❓ FAQ: Sourdough Hydration Questions Answered

What hydration should I use as a complete beginner?

Start with 75% hydration. It's forgiving, manageable, and still produces excellent sourdough. Once you're comfortable with technique and can consistently judge fermentation, increase to 80%.

Can I use the same hydration for whole wheat sourdough?

Whole wheat flour absorbs more water, so reduce your hydration by 3-5%. If your white sourdough recipe is 80%, try 75-77% for whole wheat versions.

How do I know if my hydration is too high?

The dough becomes extremely sticky and difficult to handle. It'll spread rather than rise. If this happens, reduce hydration by 2-3% on your next bake.

Does room temperature affect what hydration I should use?

Yes! Warmer environments speed fermentation. In summer, you might reduce hydration slightly or extend cold fermentation. Cold kitchens might benefit from slightly higher hydration to encourage rise.

Is 90% hydration really better than 80%?

It creates more
