I just noticed that Vargo sells a plastic bottle specifically designed as an alcohol fuel bottle. The 8 ounce bottle weighs only 9.07 g. I have no experience with it, but lt looks like a good choice.
I recall reading that and figuring, what the heck, and using it anyway. I even tried to see if there was some sort of liner inside the aluminum on the inside, but don't remember seeing one and not really knowing what could happen--it must be a corrosion thing, kinda like you get that funny white dust going on with aluminum sometimes.
Anyway, I used it anyway and I dont think I kept alcohol in it when back from trips, but could be wrong, would have to check.
If it is a corrosion thing, I suspect the issue is because of the pressurizing that takes place with a pump system like for with a Whisper Lite or whatever, and they dont want any risk of leakage due to the pressure and seals or something.
