Kombucha Bottling Kit - Includes 7 Glass Flip Top Bottles + Compact Collapsable Silicone Funnel + Cleaning Brush | Airtight, High-Pressure Bottles For Fermenting Kombucha, Kefir, Ginger Beer, etc

These bottles work great for brewing Kombucha. They give your brew a professional look, great quality (no blow ups), and the grommets are good quality.

Perfect for kombucha! They hold up REALLY well to the pressure if you are doing a 2nd brew. I accidentally left a few bottles brewing for too long, when I opened the bottles it was like a volcano eruption. Seriously, my poor ceiling haha Must be some nice glass thickness and quality closures to withstand pressure like that. Love that the kit comes with a bottle brush for easy cleaning. Would 100%buy again if I ever needed more bottles.

All arrived in order, I called the seller to ask a couple questions and they were fantastic, we geeked out a bit talking fermentation and they directed me to their very informative website.

While the whole set was pretty good and complete for someone new starting to brew Kombucha, but two issues are - one of the bottles as shown in the image had some crack where the flip-top is attached to the bottle and the glass chipped and fell into the bottle when I opened it for the first time. Other thing is that the set is quite pricey for the contents.

At first I was pleased with the bottles but after only a few months of careful use, several of the fasteners on the lid have bent and now I can’t ever be sure they sealed properly as it will often just bend and open back up. I’ve thrown away 2 of the 6 because the metal on the stoppers won’t seal and tonight I tossed a third after the entire glass neck broke when I flipped open the bottle.
