400 Year Old History Black Death Sourdough Starter Culture - Active & Live Organic Sourdough Starter for Baking - For Artisan Bread, Pizza Dough, Waffles & More

Great starter and super easy to get going! Made a loaf 6 days after receiving the starter. Awesome flavor and texture. Perfect instructions as well. Thank you!

I couldn't help but be curious about a long living starter! I decided to go with the oldest one. It shipped promptly, and arrived sooner than expected. It was well packaged. The seal on the jar was intact. When it hissed open I was met with a rich aroma. I got roughly 60 grams of starter and fed it at 1:1:1 with unbleached bread flour. Very quickly I was seeing activity and a healthy rise. There was lots of active bubbling to be seen! The first time around took about 6 hours to peak, give or take. Every 1:1:1 feeding after that had it doubling and then peaking in less than 4 in my warm kitchen. I fed it peak to peak 3 times before I baked with it. The first loaf turned out beautifully! The rise in the dough was quick and consistent. I did have medium rye for 1/6th of the flour and the rest bread flour, all King Arthur Organic Unbleached. The rye does get a faster rise, but this is my usual blend and this rose noticeably faster. The dough smelled heavenly. It did have its own distinct characteristics in smell. It was fascinating to see how this starter behaved in comparison to my previous starter. Even during the long cold proofing my loaf rose a bit more with this strain. Everything looked and felt good. Definitely had a distinct higher performance. I finally got my loaf into the oven. The oven spring on the loaf was very good! The crumb was lovely. Even though I served it before it fully cooled it was still fluffy and light. The bread had delicious and distinct aromatics! This starter certainly has character. I asked the seller about this strains origins and history. They responded quickly with some really interesting information! I was so jazzed to read about it. This strain in particular is in a European Sourdough Museum (Belgium, I believe) . I'm going to look into that museum to see if I can see what details their testing found. Since this strain has some early origin lore in Wales, I had to think of a proper name. Since legends say that's where Merlin came from, I felt I needed to honor that. Since I already have a strain named Sir Lanceloaf (Since I use King Arthur flour mostly) i had to tie it all together. As I watched the starter rising it occurred to me. I named it Excalibread. If you're even the mildest bit curious, or just starting your own Sourdough Journey, I cannot recommend this brand enough. I can't recommend this strain enough! It's a powerful and healthy little starter! I was so pleased with my loaf that I decided to let Sir Lanceloaf take a fridge vacation and I'll be maintaining Excalibread on the counter for the foreseeable future. It was such a great experience all around. So, allow me to be the little Amazon devil on your shoulder, add to cart!!!

When my 900-year-old sourdough starter arrived, it was very watery and clearly hungry from its long journey. With a little patience, care, and love, I fed it faithfully and watched it slowly come back to life. After three days, it fully activated—bubbly, strong, and full of character. The reward was incredible. I baked the most delicious and perfectly textured sourdough bread, with a beautiful rise, crisp crust, and rich, deep flavor that only a well-aged starter can give. It truly felt like baking with living history. An amazing experience for any sourdough lover who values tradition, patience, and exceptional results

The quality of this starter is amazing. It tripled in size after only one feeding, within 6 hours. And it’s already bubbly and looks ready to use. This picture shows it after the first feeding 6 hour later. The rubber band is where it started. It also came with instructions on how exactly to care for it as soon as you get it and those are what I followed. Living dough website also has a chat feature and using it connects you right with the owners and they answered any questions I had and were very friendly. Would definitely recommend.

This living dough is a great product. It made the perfect bagels and they tasted amazing. The living dough was easy to put together and it raised really good. My child had an awesome time making it with me. I’d buy again.

As someone who appreciates things built to last, I was drawn to the history of this 233-year-old San Francisco culture. After testing it out for several weeks, it has become the reliable structural base for all my baking. Technical Observations: Vitality: The starter arrived active and "live". Within just a few feedings, the "structural integrity" of the bubbles was incredible. It doubles in size predictably, which is exactly what you want for a consistent rise. Flavor Profile: It delivers that classic, deep San Francisco tang. It’s not just a superficial flavor; it’s baked into the very "joists" of the bread. Versatility: I’ve used this for artisanal loaves, pizza dough, and even waffles. In every application, the fermentation was strong enough to support a heavy crumb. Pro-Tip for Home Bakers: Make sure your "environment" is right. Like pouring concrete, sourdough needs the right temperature to set properly. I found that keeping it in a slightly warmer spot during the first few days helped it establish a robust foundation. The Verdict: If you want to move away from store-bought yeast and build your baking skills on something with history and strength, this is it. It’s a small investment for a lifetime of better bread.

Shipping through USPS didn't make sense. It took several days to arrive but it was still alive and created my bread.

Very active starter and easy to maintain. Thank you for having a starter raised on Einkorn flour so that it is safe for those of us with gluten issues. We use the starter for both Einkorn and regular wheat breads and it works just fine in both.
