First-time sourdough guy here. I wasn’t expecting to write a glowing review of dried microbes... and yet, here we are. This starter worked brilliantly. All it needed was a jar, an appropriate cover, and some flour and water. It revived quickly, smelled alive and tangy by Day 2, and led to a proper, honest-to-goodness sourdough loaf I was proud to slice into. But what really impressed me was the customer support. On Day 1, I sent a quick message to the seller with a photo and a “Not sure I’m doing this right?” question. Fifteen minutes later, I received a kind, detailed reply from someone named Heli, who clearly knew their stuff and genuinely wanted to help. Different flours and absorption rates are a thing, apparently. Their guidance helped get my starter on track, and the follow-up made it clear this wasn't a one-off. That kind of support gave me real confidence going into my first bake. What I liked: - Fast, consistent fermentation once it got going - Clear and usable instructions - Thoughtful, responsive customer service (not a bot!) - Clean, organic ingredients (brown rice flour, AP flour, wild yeast) - Arrived well packaged What to know: - It’s not the cheapest starter out there, but the quality and support easily justify the price - Like all sourdough, it still needs a bit of love—don’t expect set-it-and-forget-it results (but if you’re here, you probably already know that) Bottom line: If you’re new to sourdough and want to skip the mess of building a starter from scratch, this is a reliable, beginner-friendly option that still feels authentic. My dough rose beautifully and baked like a dream. For seasoned bakers, this could be a great backup or a way to try a different regional flavour. Either way, I highly recommend it. Solid 5 stars.

Worked great! Followed the instructions and had no issues! I’ve been using and giving away starter like mad! Just dehydrated some so I can have a little sourdough feeding vacation! When feeding I use 1/4 cup bread flour and 1/4 cup unbleached flour or Einkorn flour and 1/2 cup water. Keep it warm while it’s going thru its feeding! Great bread, biscuits and next up, pretzels! So delish!!!

I was interested in trying sourdough, but I didn't want to spend weeks nurturing a starter from scratch with so-so odds of success. Instead I bought a packet of Captain Sourpants starter culture, and that was a SMART MOVE. The instructions are so simple to follow. I could see visible bubbling about three days in, and it seemed like the activity ramped up steadily from that point on. By day 7 it was doubling so nicely in a matter of hours that I decided to give it a try, and I got a beautiful bake from it. I have my second batch of dough bulk fermenting as we speak. This is a fantastic product if you want to get into sourdough but feel intimidated by the starter process.

Wonderful starter! I was struggling to make my own starter so decided to try a dehydrated starter. Super simple instructions. Easy to follow. Great product. Less than a week and I have an active, healthy bubbly starter!

I am an experienced sourdough bread maker who forgot my starter at home (I am visiting family out of country for 3 months). This very tedious procedure wasted a great deal of time and expensive organic flour just trying to make it work. After 5 days of the process, it finally appeared to be mature enough to make bread. I am very disappointed with the result. The dough did not rise as it should and the texture is very tough. Nothing at all like what I make from my starter. This was a very costly, frustrating and time consuming purchase.
