Product Details

For best results, do not use an oxidizing cleaner or sanitizer such as One-Step or Easy Clean on caps. Other sanitizers such as Iodophor or Star San work fine. Caps are activated when wet and should only be wet just before or after bottling, do not attempt to store and reuse caps that have been exposed to liquid.

Silver caps work for me
These caps work great. They seal with no leaks. The silver caps it makes writing on the top easy with flavor.

Works flawlessly
I've switched to using these exclusively because they work so well. Have had zero issues over 10+ batches.

no carbonation
i bottled two different beers the same day and i used the regular NON oxygen caps on one and the carbonation is fine, but i used these on another one and got no carbonation from them. anyone ever run across this problem?

Response from Northern Brewer
I would check to see if the caps are sealing well. You can test it by putting a bottle of beer into a bucket of water. Make sure the bottle is upright, so the air in the bottle is at the top near the cap. If the seal isn't tight, you'll see bubbles leaking out of the cap. If this is the case, let us know and we'll replace the caps, and we could probably also replace the beer! Otherwise, the lack of carbonation could be due to the beer itself. If one batch carbed up but the other did not, it may be that the one batch simply has more healthy yeast left. This can happen if one yeast strain is more flocculant than another, or if one beer was aged in a secondary and the other was not. The best thing to do in this case is to swirl the bottles to rouse the yeast off the bottom, put the bottles someplace warm, and give it another week or two.

So far so good
I have used these on several batches and see no side effects. Beer turns out nice and well carbonated with no after taste

These are greats caps if you plan to keep a beer for more than a couple of months. Otherwise, just buy the regular one.

AHS low carb ale
The best kit beer I've ever made! My only problem is that I have to decide what other kit to try

Never have oxidation problems when using these caps. Even had a batch once where half way done bottling, I realized I forgot priming sugar. So I dumped all the bottles back into the bottling bucket, added my priming sugar, and bottled the batch. Even that batch had no oxidation problems using these caps.These used to come in bags with 144 caps, now they have 120 for the same price? Really Northern Brewer?
