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.

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!

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 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.

I’m new to sourdough, and this was the easiest way to kick-start a starter. Yes, you can absolutely make one from scratch with just flour and water—the wild yeast in the air will eventually do its thing—but this little packet lets you skip the waiting and start with an established, mature strain. Older strains tend to produce better bread with more complex flavor, and this one delivers. It took about seven days for the starter to develop that classic, wonderful sourdough aroma, and it’s been strong and active ever since. I’m baking nearly every day now, typically using about 150 g of starter with 450 g of flour, 320 g of water, and 10 g of salt for a great loaf. Well worth the effort. Do yourself a favor and pair it with proper sourdough starter jars—it makes the whole process much easier. https://a.co/d/fgKolmV
