ingredients — all three of them
Three things, nothing else. US-milled organic bread flour — 12.7% protein, unbleached, unbromated, milled from a single varietal of hard red winter wheat. Triple-filtered Great Lakes water — carbon block, then reverse osmosis, then re-mineralized so the wild yeast gets the calcium and magnesium it actually wants. Wild yeast from one mother culture captured in our kitchen in 2022 and hand-fed ever since — Lactobacillus + Saccharomyces, never frozen, never restarted. No commercial yeast, no preservatives, no dough conditioners, no bleach or bromate, no sweeteners.where every ingredient comes from
I've never baked bread before. Is this the wrong place to start?
It's the right one. Most people who buy this have never baked sourdough — the jar arrives already active, so your first feed is the whole job, and the tutorial walks every step with photos and a video. If it goes sideways, the day-7 promise above covers you.

    Great starter, great results!

    This sourdough starter was so easy to activate and became bubbly within about 36 hours. The instructions were clear, and everything worked exactly as promised. My first loaf had a wonderful artisan flavor with just the right amount of tang and rose beautifully. I also love that it's organic, made in the USA, and comes from a family bakery.

    Absolutely loved the bread

    Absolutely loved the bread i baked with this starter, i just wish there was an option for 2-week delivery, i run out too quickly to bake as much as id like.

    Sourdough made easy

    This is a great product. Takes the fear out of making a good sourdough loaf. The instructions were easy to follow and the bread was delicious! Even the dense bread hater in my house loved it. My granddaughter loved helping feed the starter and got so excited to see how it bubbled — I keep a rubber band on my jar to mark where it was before feeding and she was always surprised to see how much it grew afterwards. I will definitely buy this again.

    Amazing!

    This sourdough starter culture was incredibly easy to get going and produced an active, bubbly starter much faster than I expected. The instructions were simple to follow, even for a beginner. Within a few days I was baking delicious homemade sourdough with great rise and amazing flavor. A little goes a long way, and the quality is excellent.
