O2 Barrier vs Scavenger Crowns
Looking for some knowledge here from the community. I know the Barrier crowns prevent O2 ingress over time. The Scavenger, well, scavenges O2 in the headspace and any that sneaks in from the outside using a sulfite/ascorbate combo. I have heard that there is concern about the scavenger cap also absorbing some aroma or flavor compounds from the beer.
Anyone ever heard of this or have any experience they can share? I want to order a few hundred thousand crowns in a few weeks and have to choose. I was assuming the scavenger would be better for the quality of our beer during storage, but now I'm not so sure I know anything - as seems to be the norm in this biz .
Thanks for any help or info to make my decision more clear. Cheers. Andrew
But the use of either of these does not mean you can abuse the beer and ignore good oxygen control all the way through to capping. They only work for minute amounts of oxygen - the icing on the cake so to speak
Just to second Dick Murton's point above:
There is nothing better to control oxidised flavour defects than good oxygen control during the process.
