I've searched around and seen the differences between PET, multi-layer PET, HDPE, LDPE, and glass, but found almost nothing about the oxygen permeability of PP (polypropylene). I'm planning on aging a couple gallons of my current brew for around 8 months or so and am looking at what type of container I can use. I was originally going to use PET 2l bottles, thinking that since recipes like Apfelwine are aged for months in better bottles (PET plastic) it'd be fine, but now I'm convinced that the thickness of better bottles is a multi-layer PET with some other plastic providing the oxygen barrier and 2l bottles would end up leaving the brew oxidized and ruined. So I looked into HDPE and read that people are having issues with oxygenation after only a couple months. Now I'm looking into polypropylene, but can't find any good data on it. I ask about these because I get these buckets for free and would prefer to use them over spending money on better bottles I'll almost never use. All my brew buckets are HDPE or PP, cheap or free, and most importantly, stackable. I'd like any bulk aging containers to share some of those characteristics. FYI, I'm not concerned with bottle carbing at all, so pressure requirements are null.
