Replacement GT Synergy/KeVita Kombucha Bottle Caps

Many homebrewers re-use GT's Kombucha bottles for their own brew. However, a common complaint is that the caps become impossible to remove after awhile due to wear. These polyseal 38mm caps fit perfectly on GT and Synergy Kombucha bottles; KeVita bottles; standard growlers or any container that has a 38mm diameter opening. As an added bonus, they hold in the carbonation even better than the original caps! Made with brew safe materials, dishwasher safe.


  • 38mm size (38/400) - fits regular size and Jumbo GT's Kombucha bottles, as well as any other bottles with 38mm size opening

  • Polyseal holds in carbonation

  • Dishwasher safe


Dishwasher safe or simply rinse in clean water, no need for soap unless mold is present. Air dry. Small drops of liquid may become contained between the liner and the cap, this is normal and not an issue.

Wow! I was so excited to find these! Exactly what I needed. They fit my GT bottles, but more importantly they fit every growler I've ever tried them on, which is why I bought them in the first place. Thank you!

Reviewed by L.C., 08/28/2020

Purchased these caps for use on GT's bottles. Such an improvement over the one-time-use original caps for sealing in gaz/fizz! Nothing lasts forever. This is the second bunch I've gotten. After somewhere between 2-3 years (years!!) of repeated/constant use the seal capacity must simply undergo wear and tear, less effective at preserving gaz so they've done their time. Worth the +/- $1 apiece for the gaz retention results over a couple to several years. Love love love bubbles in my brew. If you're reusing GT's bottles and want to lock in fizz get these! You won't regret it. Sounds like an ad, doesn't it? I promise I'm a real brewer!

When I began brewing, I bought some swing top bottles, but started saving my GT’s bottles as well because I heard you could use them.  You certainly can use them, but your kombucha will be flat!  The fix for this is to buy these lids, they work flawlessly!  The tip on getting the labels off was also priceless!  The only thing I would add is that a squirt or two of Goo Gone is needed to get rid of any glue that remains on the bottle.

I love these caps! I have never had a bottle explode, leak, or be difficult to un-cap. My booch is wonderfully fizzy after flavoring and secondary fermentation. I originally ordered a dozen, and found that I needed more as I got more productive. 2 dozen seem to keep me set, with some bottles in the fridge, and some doing their secondary fermenting. These caps also fit on a lot of other brands of recycled Kombucha bottles besides GT. Some brands have 12 oz bottles, and I like those because I can try out more of Hannah's crazy good flavoring recipes as I bottle. My friends say that my Kombucha is always the best they've had, and I tell them I'm just following the recipes in "The Big Book of Kombucha"

These caps are absolutely a must if you are reusing GT-style bottles! They also fit perfectly on 64 oz growlers!!! This is the second time I have bought them. When I first started brewing Kombucha, I was on a quest to make it more and more effervescent to please my beloved and others in my family whom I needed to be drinking the vast amounts of booch I was brewing. The way you cap during your second ferment is essential to keeping your brew truly sparkly. The caps that come with the GT bottles work OK for a few batches but quickly wear down, leak and become very difficult to remove. These caps, like everything else I have ever purchased from Kombucha Kamp, are amazing! I love this product and this site, I can't recommend either enough.

Absolutely LOVE these bottle caps! I bought about 30 Kevita and 30 GT bottles to reuse for myself but was super frustrated with the lids they came with. Not only did they leak, they did not keep the carbonation very well at all so I spent much more time brewing. With these replacements lids, they no longer leak and they keep the carbonation in much better and longer. As a result, I can now brew larger batches which saves me a tremendous amount of time as I keep 30-60 bottles of Kombucha and water kefir in my second fridge at all times. I'm actually a Kombucha and water kefir junkie! I drink about 6 bottles a day myself. I do share with my daughter-in-law and my co-workers but for the most part, they're all for me!

When I do, or if I'm taking the bottle out, I simply switch with one of the few white caps that were saved from the original bottles. The black caps work great and I love that I don't have to worry about using them again and again. They are easy to clean and made of a good product that ensures fizz!

I wanted to recycle my glass GT bottles for making my own Kombucha. The white caps that came with bottles seemed to wear out. They became very hard to open and some cracked. The replacement caps have worked well and have a good seal.

This replacement caps fit my store bought kombucha bottles perfectly! Accidentally broke the originals, but these kept me from having to trash the bottle! Seems like they are easier to twist open. Awesome caps, love the design. Keeps the carbonation in a little better!

I ordered two dozen of these lids and LOVE them!! I didn't want to get into the Grolsch-type bottles at this time and I had a good supply of GT Synergy bottles. I am so glad I ordered these lids to fit my bottles. They hold the carbonation really well and are high quality.

These caps are so great. I kept all of my old GT bottles, and the white caps were so hard to remove. The caps are not only easier to use, but hold carbonation better. I'm going to order more next time:). Thanks!

These replacement caps are a winner! I knew the moment I put one on my re-used bottle just by the way it slipped it is much better than the white caps.

Ordered the GT bottle caps. Really like them because I've had beer bottles with caps I had a few that exploded, so now I prefer the GT bottles besides they're easy to store in my fridge. These caps are great.

I just open my first KT using the replacement caps I ordered , they worked phenomonally ! My fizz was great and I was able to easily remove the cover which I have a hard time with reusing the ones that come on the original bottles . I also like the fact that they're black and don't get mixed up with my other covers . Thank you Hannah for ANOTHER winning product

Love these caps! They're nice and heavy plus the clear part pops out for cleaning. They really do hold in more carbonation. I tested a couple with mineral water before bottling a gallon and a half of kombucha beer with my dozen caps.
