Currently using mason jars with great results and virtually no loss of alcohol over 2 years in jars…
Handling and storing the amount I may try to scale up to though will become an issue even using 1/2 gallon ones…

Hear me out... Wrap the jug in cling wrap...
Yeah I plan on keeping them in milk crates to help prevent issues…
Not air tight.

The mason jars lol
Dropping 1/2 gallon mason jars is the big loss leader in the homemade vanilla extract world lol
Tricky. A pail with the lid you showed will be good, all you need to do is improve the seal? Could you clamp, providing pressure to the silicon seal. Wax it, or clingfilm on top? Those lids only didn't work for me due to the pull off design, some have grippers which are better
This one has to clamps

Nice
If you put the mason jar inside that steel jug and put the steel jug inside your milk crate, I think you have a optimal solution to prevent air leaks.
