She's definitely alive!
I bought this many months ago and still have it going, so she's durable and tough! It made delicious fresh bread and was easy to reactivate. There were giant bubbles within 2 days, and you could look at the starter and tell she was ALIVE! She looks beautiful and makes a great sourdough crumb and texture. Sourdough is so incredibly healthy and this starter makes it easy to, well, get started!

Canadian-made, beginner-friendly, and seriously backed by real support
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.

Captain Sourpants Mature Sourdough Starter Culture
This is my very first attempt at growing sourdough starter and baking sourdough bread! I am kind of nervous about getting it right, so your warranty makes me feel better! The directions are very clear and this is my first day. It is exciting to be learning something new. My husband is diabetic and misses bread. It seems the sourdough bread has a lower glycemic index. I hope to be baking bread in a week or so. I have hight hopes. :) I have read of many people who try to make their own sourdough starter and have failed miserably, and they say to just buy the starter--so I did

This works great!
Fantastic results , so happy. I have never been successful making my own starter. This was bubbling 2-3 days in. I did have to adjust the water as I know it was too dry. I used bottled water. I made everything bagel crackers with my discard and we couldn't stop eating them. ( Ruth- Homesteading with the Zimmermans channel) Yesterday the starter overflowed , I set the jar in a small bowl today and a larger jar. First bake day on Saturday so I am hoping for good results. I will update .
