Description

Classic White Sourdough Starter Culture

Our Classic White Sourdough is the cornerstone of the artisanal kitchen, carrying a pure, hand-fed lineage that delivers the iconic flavour profile of traditional European hearth bread.

This culture is a baker’s essential. Favoured for its mild sweetness and incredible versatility, it serves as the perfect biological engine for everything from crispy baguettes to airy focaccia. Unlike more aggressive strains, this white wheat culture allows the natural aroma of high quality grains to shine through.

This is a balanced, high performance, and exceptionally active starter!

NutriBrew Mastery Tip: The Windowpane Test

To achieve an airy, open crumb with white sourdough, gluten development is key. After mixing, perform the Windowpane Test: stretch a small piece of dough; if it thins out enough to see light through it without tearing, your protein structure is strong enough to trap the gases produced by your active starter.

Master the Art of the Classic Loaf

Whether you are a first time baker or a seasoned pro, our White Sourdough culture arrives at peak vitality. Because we feed our starters daily with premium unbleached flour, you receive a resilient, high performance culture that delivers a superior rise and a crisp, golden shattered crust from your very first bake.

Authentic Heirloom Starters for the Modern Kitchen

NutriBrew offers a curated collection of premium, high activity sourdough starters, each with a centuries old lineage. We believe a truly great bread is shaped by the history of its cultivation. When you bake with our live cultures, you aren’t just making bread, you are inheriting a unique biological story to be passed down through your own family for generations.

Ready to try a more specialised heirloom profile?
While this white starter is our most versatile artisan companion, those seeking the iconic West Coast acidity should explore our San Francisco Starter. For a resilient culture that thrives in cooler kitchens, we highly recommend our Alaskan Heirloom.

White Sourdough Starter: Frequently Asked Questions


Our White sourdough cultures are shipped “active and wet” in a specialised, nutrient dense flour base. This protective environment preserves the wild yeast and lactic acid bacteria in a stable state, ensuring they remain 100% viable for up to 14 days in transit. Unlike dehydrated powders, our live starter is ready to bubble and bake almost immediately upon arrival.

No. This is a genuine heirloom culture with a lineage spanning decades. With simple weekly feedings of flour and water, your starter is biologically sustainable forever. In fact, the flavour profile of white sourdough often becomes more refined and nuanced the longer you maintain it in your local environment.

The essentials are likely already in your kitchen: a clean glass jar, a digital scale, and a wooden spoon. While a Dutch oven is popular for achieving a professional “shattered” crust, our vigorous starter will produce fantastic artisanal results in a standard oven with a simple tray of water for steam.

Every kitchen has a unique microbial “fingerprint.” Your starter may require a 24 to 48 hour “acclimation period” to adjust to your local water and specific flour brand. By the second or third feeding, the wild yeast will fully activate, providing the gas production needed for a perfect, airy crumb.

Aim for a thick pancake batter consistency. When you stir your white starter, it should be smooth and elastic. If it feels too watery, the bubbles will rise to the top and escape too quickly. A slightly thicker consistency helps the wild yeast trap gas effectively, which is the secret to getting a massive rise and an airy crumb in your bread.

A healthy white heirloom starter typically has a clean and pleasantly yeasty aroma with a mild fruity undertone. As it reaches its peak, you will notice a sharper tang. This balanced scent indicates that the lactic acid bacteria are healthy and creating the superior depth of flavour that makes home baked sourdough so much better than shop bought bread.

Not at all. Clear or slightly grey liquid is simply hooch, a natural byproduct of fermentation. It is your starter telling you that it has used up its food and is ready for a fresh feeding of flour and water. You can stir it back in to intensify the sourdough flavour or pour it off if you prefer your bread to have a milder and sweeter taste.

White sourdough is incredibly resilient. If you are not baking every day, simply keep your starter in the refrigerator. The cold temperature significantly slows down the activity of the yeast and bacteria. A single feeding once a week is all that is required to maintain the vitality of the culture for a lifetime of future baking.

The best sign is when the starter has at least doubled in size and the top is covered in small bubbles. The texture should feel light and airy like a mousse. A popular test is to drop a small spoonful into a glass of water; if it floats on the surface, the wild yeast has produced enough gas to leaven your dough for a perfect artisanal rise.
