Looking for: ethanol resistant oxygen permeable membrane

[Single Malt Yinzer]

So part of aging is slowly oxidizing the distillate. With small barrels the distillate can get over oaked faster than the oxidation process can adequately enhance the product. The oaking process can be done other ways with oak fingers/cubes/chips. With that part of the barrel equation removed it allows for isolation of oxidation process. In pursuit of that I've been looking for an ethanol resistant oxygen permeable membrane. But I can't figure out which one is best for this. I've searched for it but haven't found anything that would be easy to get to test.

Here's a good beer thread with some charts: https://www.beeradvocate.com/community/ ... on.248425/" onclick="window.open(this.href);return false;" rel="nofollow

Goals:
- Oxygen permeability similar to wood (we can test later higher or lower)
- Resistance to high ethanol content (60+%)
- Lowish cost
- Reuseablity (especially if it's costly)

I would ultimately like something I could use to cover a larger jar (a gallon or more) so that I could oak at the same time. I would like it to be a film or thin paper like substance so that it is easy to work with. (Hey if you're going to ask for something might as well ask for all the bells and whistles).

So who can find this magic thing I'm looking for??? Any suggestions for something else? Any ideas for other goals?
