I spray with sanitizer. Works fine, does not seem to negatively affect the caps. I like the insurance of sanitizing because I store my caps in open bags around my other equipment, some of which has grain dust and has been around my mixed fermentations.
I have no idea whether they definitely work better at avoiding oxygen reactions with the beer but the liner inside seems thicker and creates a better seal. That’s the main selling point for me.
I worked at my lhbs about 10 years ago or so, and we packaged the bottle caps by weight in the same room we milled grain and what not. I imagine there was copious amounts of grain dust lacto and what not floating around everywhere. I think its such an easy step to sanitize.
yeah, we certainly used the same scale for everything except big orders, we had a larger floor scale for that. I’ll be bottling a saison tomorrow and have about a dozen of the oxygen bottle caps sitting around, Ill use those and then some normal ones and see if I can tell a difference.
The problem with sanitation in and around the brewery is that we are actually growing and selecting those “bad”bugs because of the very nature of brewing.
I think majorvices is probably right. When I first started brewing, I brewed several batches before I realized thatI was supposed to besanitizing the bottles after cleaning them. How many infected bottles did I end up with? Zero! Maybe I was lucky or maybe six or so brewing sessions didn’t allow enough generations for the nasty mutations to become established.
