Reliable and consistent
I rehydrated this Gluten-Free Sourdough Starter and was pleasantly surprised by how reliably it came back to life. I’m in Southern California, and it took about 3 days of consistent feeding to become clearly active, which felt very reasonable for a gluten-free starter. Once established, it showed good fermentation: visible rise, lots of fine bubbles, and that pleasantly tangy, yogurt-like aroma you want in a healthy starter. As expected with gluten-free starters, it doesn’t behave exactly like a wheat starter (it collapses more quickly and doesn’t hold structure in the same way), but it’s clearly strong and active when fed appropriately. Overall, this is a perfect option if you want a dependable gluten-free sourdough starter without having to build one from scratch. With patience and proper feeding ratios, it becomes a very usable and consistent starter for gluten-free sourdough baking.

Fantastic Stater
This starter is exactly as advertised. I needed to use three different starters though, and let me tell you why so you don’t make the same mistakes I made. The first batch of starter barely grew and developed a slight acetone smell after a week of trying. I contacted the seller and they were amazing. They explained that my problem was probably environmental and they were right. It had been on my kitchen counter and the temperature fluctuated too much, so they asked me to try again, and I did. The second batch was done in the oven with the oven light on. This was the perfect temperature and after four days it was ready to use, but my housemate accidentally turned on the oven destroying my batch. So the next idea was to cover the stove controls with post it notes, The third batch was amazing! The post it notes helped in a household where multi people use appliances and prevents any oopsies. On the fourth day, I made focaccia because my dough was too soft, had it sit in the refrigerator for three days and allowed it to proof before I baked it. It had a wonderful flavor and texture, I used an inverted cookie sheet with a pan of water on top to seal in the steam, and it stuck to the bottom, so next time I will use a sheet of parchment paper Then I made an actual round loaf in my very inexpensive dutch oven. I used a small kitchen bowl lined with flour and cheesecloth, covered it to make the right size loaf, nothing fancy, nothing expensive, and let it cure in the refrigerator for three days, I put parchment paper in a warm Dutch oven and baked it to a golden brown. It made great grilled cheese sandwiches. Nice flavor, mildly tangy. Now my third batch is jumbo cupcake size sour dough rounds for Christmas dinner. Those are prepared in a 9*13 pan with giant cupcake papers. It will also cure for three days, proof and then bake it to a golden brown brown. The starter that I have stored in my fridge activates almost immediately and is ready to use the same day I feed it. Fantastic starter

Great Starter for a novice like me!
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!!!

Not so hard, easy to get started.
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

Perfect way to get started with sourdough!
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.

Great starter, might not be appropriate for whole wheat flour
The sourdough starter is good and consistently bubbled up the first 5-6 days with regular feeding. Although I was using all purpose flower for the feeding, I used whole wheat flour for making the main dough and that did not bake as expected. Maybe it doesn't work well with whole wheat bread during bulk fermentation. Otherwise very good starter.

Quickly active and easy to use!
Starter worked great! Came with instructions that were easy to follow. I am on day 7 today and my first loaf was baked today. Honestly I think I could’ve baked at day 5. I saw a consistent rise/double in my jar at day 3 and onward.

This sourdough starter did not disappoint. It was doubling and bubbling within 36 hours and ready for baking on day 3! I have to give a shoutout to the customer service agent who was quick to answer my questions and assure me that I was doing all the right things. I would definitely recommend this starter to anyone who wants to try baking sourdough bread.
P**!
Perfect!

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!
