About Us

Welcome to The Sourdough Labs – your trusted home for all things sourdough. We specialise in premium sourdough starters and kits, offering a carefully curated range designed to help every baker – from complete beginners to seasoned pros – create truly artisan sourdough bread from scratch.

At The Sourdough Labs, our journey began in a chemistry lab and ended up in the kitchen, where science meets artisanal craft. Driven by curiosity and a love for experimentation, I began my sourdough adventure while pursuing a PhD in chemical engineering. Like many, I sought solace and creativity during the pandemic, turning hobbies into passions—particularly baking sourdough. But finding a robust, active sourdough starter proved more challenging than anticipated, with many store-bought starters lacking vigor and consistency.

Refusing to settle, I transformed my kitchen into a personal laboratory, meticulously capturing and cultivating wild yeasts. Over the past five years, I’ve honed my process, testing countless variables to ensure that every starter is resilient, vibrant, and brimming with flavour. Today, I’m proud to share Steve the Sourdough Starter—a mild yet robust culture with a hint of sweetness that adapts beautifully to any recipe, from a quick bake to a long, flavorful ferment.

With a pinch of patience and a dash of care, Steve is designed to be your steadfast companion in the kitchen, flourishing with any flour and producing beautifully bubbling doughs that bring homemade sourdough to life.

Our collection includes a diverse selection of live & dried sourdough cultures, including classic white, wholemeal, rye, and even heritage grain starters, each nurtured and ready to bring your baking to life. Whether you're after a robust, tangy flavour or a milder, more versatile starter, we’ve got the perfect match for your kitchen.

At The Sourdough Labs, we use only the finest natural ingredients, and every starter is handcrafted in the UK to ensure quality, authenticity, and consistency. Alongside our starters, you’ll find essential baking tools, step-by-step guides, and expert tips to support your sourdough success.
