Are we using oxygen scarifying crown caps correctly?

Postby LeeH » Sun Oct 16, 2016 15:32

I stumbled across by accident a post on a US forum regarding oxygen absorbing caps.

It was said they are activated by liquid so pre soaking them in starsan rendered them ineffective if left for too long. So basically dip and cap.

If you don't bother sanitising like some, you must invert the bottle after capping or they don't work.

Just thought it might be of use if like me you soaked your caps for a hour or so like I did.

HTH.

Thank you. I did always wonder why they did not exhaust themselves in the oxygen left in the packaging before use!

Malt Miller do Oxygen scavenging 26mm caps for about a penny each. I now use CO2 with a beer gun so not an issue but I did use them, incorrectly it seems for quite a while !

Ha live n learn.. I only bottle the excess from kegging as a rule and use mainly flip tops anyway, so perhaps have ignored news regarding crown caps and let this development slip by ;)

Aren't all his crown caps oxygen scavenging?

I often soak mine for an hour or so, so I might be doing it wrong. I can just dip them in starsan before placing them on the bottles just as easily.

Never enough time....

I don't think all of them are. Most maybe.

I normally put crown caps in a jug of starsan while bottling. Can't say I've noticed any oxygenation issues, but if this is best practice, then it can't harm to tweak my process.

2016: 330L brewed (72 gallons, over 8 firkins)
2017: 105L brewed
Drinking: store-bought beer as my bar is dry
Conditioning: choc-coffee oatmeal wheat stout, various ciders, cherry 'brett' brown ale, imperial Pilsner.
Fermenting: Bock (6.5%), IPA (5.5%), Pale Ale (4.5)

Standard crown caps absorb oxygen but only if exposed to water???

Oxygen absorbing caps absorb oxygen but only when wet.

Activate too soon, they don't work.
Don't activate, they don't work.

That's the suggestion I read.
