So obvious I wasn’t going to post
But in those 39 replies, nobody has mentioned what has been my normal practice since I started drinking on camping trips. And that is the ubiquitous plastic water bottle.
Yes, horrors, I know, but it works well. The bottles are tough enough that they don’t break and lighter than about anything you can bring. Aftertastes? Well, I like a drop of water with my scotch anyway, so I don’t care about the after taste of water. Once drained, I crush the bottle to reduce its size and it goes in my trash bag. I can afford a replacement for the next trip.
Cancer from plastic water bottles is debunked as an urban myth. Look it up if you want.
Aftertastes are not always bad. Backpacking with my friend Lisa last September, the beverage of choice that we both agreed on was Grand Mariner. We reused that water bottle, filling it with H2O from the Hoh River. As we hiked out the next day, we found the slight taste of GM in the water was very agreeable! Maybe we are just lushes, as the GM flavor made the list of our trip highlights.

For short term storage
For short term, I use a Platypus bottle. They don’t impart a nasty plastic taste like Nalgene and bota bags. I wouldn’t keep the liquor in one for more than a weekend though.
Great for wine when backpacking too!
Why don’t you…
Why don’t you just travel with booze that’s sold in a plastic bottle?

No fuel bottles
Please at least run a test with this first. aluminum cans are made a little differnt from aluminum fuel bottles and alcohol can be very corrosive to aluminum causing metalic tasting scotch!
