Awesome caps!
I do not brew beer, but kombucha is my thing. I use these caps as replacements for the GT's kombucha bottles. They work great and fit both the old and the new style bottles. These caps create a flawless airtight seal so I am able to achieve the coveted FIZZ.

Seals tight and doesn't lose CO2
These caps hold in carbonation even after weeks in the fridge.

One Screw Cap To Rule Them All
Great little product, they screw on the top of the bottle to keep my precious nectar of the god's safely locked inside. Doesn't leak, Doesn't break down, and it comes in any color you want as long as the color you want is black.

Best lid for the gallon glass jugs. No rust. No rubber. Super great and durable! I've bought 32 glass jugs and lids and am thrilled! Thank you Midwest supplies!

The caps are the best. The seal our wine bottle so well. This will keep it fresh a lot longer.

Allowed for bottle conditioning
I was running low on regular bottles and these sealed tight enough to allow me to condition in the growler bottle and kept the beer fresh for a few days after opening.

Great for Tap-A-Draft Bottles
These caps seal very well with only hand tightening because of the conical seal. The seal works against the inside rim of the bottle mouth where nicks are less likely._x000D__x000D_Seem to be strong and well made using a generous amount of plastic in the basic cap._x000D__x000D_Under pressure, they are a bit tight to remove. I have found that a rubber plumber's wrench works well. Be careful of:_x000D_1. Be sure that the cap is removed slowly. There is a large volume of pressurized gas in a Tap-A-Draft._x000D_2. Do not use the plumber's wrench to tighten the cap. I immediately broke 2 in a row trying that.

They are right about these fitting most gallon jugs. I ordered the gallon jugs from Midwest and they do fit them, but these did not fit my gallon jug here at home. But, that's alright as it has a different lid, it's just not as sealed as these. I'm hoping these help with my second fermentation of Kombucha to create some fizz.

Great job of maintaining carbonation. I am impressed with the seal overall.

Great caps - Growlers
I bought these because when I bring my homebrew around, its usually in growlers. These caps fit tight and seal well. I've had them filled for a week or so and holds the carbonation well. They fit standard growlers very well. Best part, I clean them and reuse them! My uncle also had some glass half gallon jugs for his maple syrup and they fit that jug too!
