83-2HJ4-5C57 38mm Poly Seal Screw Caps (fits most 1/2 & 1 gallon jugs) [Bag of 12]

Perfecto con mis growlers

I home brew kombucha and needed caps that sealed tightly to keep in carbonation during the 2nd ferment. In reading over the Q & A's for this product, one gentleman posted that these caps do not fit the new-style Dave's GT kombucha bottles. The new bottles have a slightly different screw-thread configuration versus the previous style bottles. You can tell if you have the new-style bottles as now the "GT" is a raised design on each plastic bottle cap. (The older bottles had a smooth plastic top - no embossing.) I respectfully disagree with his answer as I am very pleased with the fact these caps do work very well on the newer style GT bottles, and I've not had a problem with them doing the job I want them to do - and that is fitting so well that no carbonation leaks out. ~~ OLDER style GT bottles: These caps fit perfectly. I've made a number of batches and the carbonation is totally contained - nothing can leak through the sides of these caps. I am now getting super fizzy (YUM!) kombucha. ~~ NEW style GT bottles: Because the screw-threads are a little closer together and configured a bit differently than the previous style bottles, these poly-seal caps don't screw/tighten down as far as the caps that come with the bottles. HOWEVER, as long as you MAKE SURE to twist them on tight, making sure they are screwed down as far as they can go, they work great! I've had absolutely no loss of carbonation when using these on the new style bottles. The fizz factor is just the same as using these caps on the old style bottles. So, I am very pleased and happy I tried them, as I have more of the new style bottles on hand than the old style. **Remember: no matter what GT bottle you're using ... make sure to really tighten the caps after filling. You should then have great success with your 2nd ferment (if all other steps in the 2nd fermenting process are done properly). UPDATE: 4/27/2017: After 9-months of using the same caps on the newer bottles I think I've had a good amount of experience with them. I still say these caps work well on the newer thread-style GT bottles almost all the time. Now you will find that the caps seem to not screw all the way down - this is due to the thread design. And after the 2nd fermentation is done, I will admit that sometimes a bottle isn't as fizzy as another. But I still have a few of the original thread-design bottles and sometimes one of those isn't as fizzy as the others (I put them in the frig after the 2nd brew as I make a number of bottles at a time). One kombucha brew can sometimes be more or less carbonated than the next as many "kombucha brewing experts" mention. But no matter what, I have always had some level of carbonation in all bottles with the newer thread-style after the 2nd brew. **What I have found is what other's have posted on other sites ... it can help to turn the cap gently to the left to get it seated on the thread, and then screw it on tight. But in a perfect world, I do wish a cap manufacturer would make caps that really fit the newer GT bottles. But the "GT" initials are embossed right into the glass on the bottom, so maybe Dave (Dave's GT) does have an exclusive on the thread design, and cap manufacturers aren't interested in catering to a very small percentage of those who are kombucha home brewers.

These arrived today, as promised. That's due to Amazon Prime. The lids are in perfect condition and DO fit the 16 oz. jars from North Mountain Supply. I wanted more than the flat 'seal' that comes with the jars. I have already re-ordered more jars and lids. Today (31 Oct. 2019) my second order arrived. All these 38mm Poly Seal Screw Caps are in great condition. There are a couple of scratches here and there and some small chips on a couple of caps. Nothing that hinders their use, probably done in manufacturing or shipping. The caps should do a good job of keeping oxygen out of my vinegar while in storage. I think they would be great for home made sauces, too.

Comme je fermente beaucoup et que je produits cidres et vinaigres, je tiens de nombreuses touries. Avec les années ces touries perdent leurs bouchons mais aussi j en achéte beaucoup dans des bazars car il m’en faut beaucoup et souvent les bouchons sont perdus ou pas vendus avec. Quand on recycle, il manque souvent de quoi pour que ce soit complet. Très bon achat pour moi, ils vont parfaitement sur mes touries . Très bon rapport, qualité prix.

Buen producto
