75 Hydration Sourdough Bread Recipe: Open Crumb Magic With Tangy Depth

This 75 hydration sourdough bread recipe delivers the perfect balance of open, airy crumb and tangy depth—no dense loaves here. The magic lies in the precise hydration level and careful fermentation process, which creates a structure so light it practically floats.

I’ve perfected this method over years of baking, and the results speak for themselves: a loaf with an irresistible crust and a crumb so open you can see through it.

The key to success is patience—both in maintaining an active starter and allowing the dough to ferment slowly. This recipe guides you through each step, from mixing to shaping and proofing, ensuring you achieve that signature sourdough flavor without the guesswork.

The higher hydration makes the dough more forgiving, but it also requires attention to timing to avoid overproofing.

By the time you pull that golden-brown loaf from the oven, you’ll have a bread that’s crisp on the outside, tender on the inside, and packed with that unmistakable tang. It’s the kind of loaf that turns sandwiches into an experience and makes toast feel like a celebration.

The open crumb isn’t just visually stunning—it’s a testament to the dough’s strength and flavor development.

Whether you’re a seasoned baker or just starting your sourdough journey, this recipe is designed to deliver consistent, professional-quality results. Let’s get started—your kitchen is about to smell like a Parisian bakery.

Ingredients for 75 hydration sourdough bread

Pantry staples meet Parisian bakery magic—just nine ingredients transform into a loaf so light it practically floats.

The flours make all the difference here. King Arthur or Caputo bread flour gives that signature open crumb, but don’t stress if you only have all-purpose—just add 1 tbsp vital wheat gluten per cup of flour. Whole wheat adds depth but can dry things out, so use no more than 10% of your total flour if you're new to sourdough. Water quality matters too—if yours tastes metallic, use filtered or let it sit out for 24 hours. The starter? It should be bubbly and smell like tangy, ripe fruit. If it’s flat or smells like vinegar, feed it once more before using.

No honey? Maple syrup or agave work in a pinch, though honey’s enzymes help with flavor development. Short on olive oil? Avocado oil or melted coconut oil are neutral substitutes. The yeast is optional but helpful if your starter’s strength varies—it acts like a backup plan. For shaping, a well-floured work surface prevents sticking, but don’t over-dust or the dough will toughen. If your kitchen’s humid, reduce flour by 1 tbsp—the dough will be stickier but more extensible. And yes, you can use this dough for calzones or focaccia—just shape differently!

This dough ferments best at 75°F (24°C), but if your kitchen’s cooler, proof it in a turned-off oven with a bowl of hot water. The shaped loaf keeps 2-3 days at room temp wrapped in a towel, or 1 week in the fridge. For longer storage, freeze the baked loaf 3 months max—warm slices in a 350°F oven for 5-10 minutes to revive that bakery-fresh crunch. Pro tip: Toast stale slices for croûtons or breadcrumbs—waste not, want not!

Step-by-step instructions for perfect 75% hydration sourdough bread

This dough handles like a dream—open crumb, tangy depth, and a satisfying crunch. Let's build it properly.

In a large mixing bowl, combine the 0.5 cup active sourdough starter, 1.5 cups water, 0.5 tsp honey, and 1 tbsp olive oil. Stir gently to dissolve the honey completely—this helps activate the starter and adds subtle sweetness. The mixture should look like a thin, shimmering batter.

Next, add the 3.5 cups all-purpose flour and 0.5 cup whole wheat flour to the bowl. Sprinkle the 0.75 tsp salt evenly over the dry ingredients, then fold in the 0.25 tsp instant yeast if using. Use a wooden spoon or dough whisk to mix until just combined—you should still see some flour streaks. Overmixing develops gluten too early, which can make the dough tough later.

Cover the bowl with a damp kitchen towel and let it rest at room temperature for 30 minutes. This initial rest allows the flour to hydrate and the gluten to begin developing naturally. You'll see the dough start to thicken slightly and pull away from the sides of the bowl.

After the rest, wet your hands with water and perform a series of stretch-and-folds every 30 minutes for 2 hours total. To do this, dip your fingers into the dough, grab a portion, stretch it upward, and fold it back over itself. Rotate the bowl between each fold to ensure even gluten development. The dough should become smoother and more elastic with each set.

During this time, the dough will rise noticeably—you'll see bubbles forming on the surface and along the sides. The ideal temperature for bulk fermentation is between 75-78°F. If your kitchen is cooler, place the dough in a slightly warm spot (like near the oven with the light on) to encourage proper fermentation. You're aiming for a 50-75% increase in volume—when the dough looks puffy and jiggly, it's ready for shaping.

Once the dough has nearly doubled in size, perform a final stretch-and-fold to tighten the gluten structure. This prepares the dough for its final shape and helps create that beautiful open crumb we're after.

Lightly dust a clean work surface with 0.25 cup cornmeal and turn out the dough. Gently shape it into a round boule by pulling the edges toward the center and tucking them under. The surface should be smooth but still slightly bubbly. Place the shaped dough, seam-side up, into a lightly greased proofing basket or a bowl lined with a floured kitchen towel.

Cover the dough with the towel or a plastic wrap and let it proof at room temperature for 1-2 hours, or until it has risen by about 50%. The dough should spring back slowly when poked with a finger—this indicates it's ready for baking. If your kitchen is warm, you might need less time; if it's cool, you may need to extend the proofing period. The goal is a well-aerated, slightly domed loaf with visible bubbles.

Preheat your oven to 450°F with a Dutch oven inside for 45 minutes. This step is crucial—it ensures a deep, crispy crust. Once preheated, carefully transfer the dough (still in its proofing basket or towel) to the hot Dutch oven. Using a sharp razor blade or lame, score the dough diagonally about ¼ inch deep. This allows the bread to expand properly and creates that classic artisan look.

Bake the bread, covered, for 20 minutes. Then remove the lid and continue baking for another 20-25 minutes, or until the crust is deep golden brown and the internal temperature reaches 205-210°F. The bread should sound hollow when tapped on the bottom—a sure sign of doneness. If the crust browns too quickly, tent the bread with foil to prevent over-browning.

Remove the bread from the Dutch oven and let it cool on a wire rack for at least 1 hour. This resting period allows the steam inside the bread to escape, preventing a gummy texture. The crust will firm up as it cools, and the crumb will develop its signature open, airy structure. Slice through the bread to reveal those beautiful, irregular holes—a testament to a well-fermented loaf.

Serve the bread warm with a smear of olive oil and a sprinkle of flaky sea salt for a simple yet elegant presentation. The combination of the tangy sourdough flavor, the open crumb, and the crispy crust makes this bread a standout. Store any leftovers in an airtight container at room temperature for up to 3 days, or freeze for longer storage.

Wine and beer pairings for this 75 hydration sourdough bread

Crisp Whites

Sourdough’s tangy depth pairs beautifully with crisp, mineral-driven white wines like Alsace Pinot Gris or Loire Valley Sauvignon Blanc. The wine’s bright acidity cuts through the bread’s richness, while its citrus notes complement the dough’s subtle sweetness from honey.

I love chilling a glass of Domaine Zind-Humbrecht Gewürztraminer—its lychee and floral notes mirror the bread’s complex fermentation. Serve slightly chilled to enhance the wine’s freshness. 🍷

Light Beers

For beer lovers, Belgian Witbier or German Helles Lager are perfect companions. The citrusy, coriander-forward profile of a Hoegaarden or Weihenstephaner Original enhances the bread’s open crumb and tangy crunch.

If you prefer something lighter, a crisp American Pale Ale (like Allagash White) balances the sourdough’s depth without overpowering it. Avoid heavy stouts—they’ll clash with the bread’s delicate structure. 🍺

Red Wine Risks

While some might reach for red wine, bold Cabernets or Syrahs can overpower this bread’s delicate crumb and tang. Instead, opt for light-bodied reds like Pinot Noir or Beaujolais—their bright acidity and red fruit notes harmonize without competing.

If you must try a red, chill it slightly to soften tannins and preserve the bread’s crispness. I’ve found Domaine Serene Pinot Noir from Oregon works beautifully. ⚠️

Non-Alcoholic Options

Don’t drink? No problem. A sparkling water with lemon (like San Pellegrino) mirrors wine’s acidity, while ginger beer (like BrewDog Ginger Beer) adds a zesty kick. For something richer, try sparkling apple cider—its effervescence cleanses the palate between bites.

Even a chilled hibiscus iced tea (with a squeeze of lime) enhances the bread’s tangy notes. 💧

Seasonal Pairings

Summer calls for crisp whites or light beers, while winter warms things up with oaked Chardonnay or amber ales. In fall, a dry Riesling (like Dr. Loosen Blue Slate) highlights the bread’s honeyed sweetness.

Spring? A rosé (like Whispering Angel) bridges the gap between light and bold. Each season transforms the pairing into a new experience. 🌿
