I very recently binned, well recycled around 40 Brewdog, Blue Moon and Hop House bottles (330mm) i had collected, as i just didn't use them and they took valuable space up.
Wish i had have known you wanted 330's
@Ghillie .
I know exactly what you mean about Brewdog bottles, they are by far the hardest i have come across.
Anyway, all labels other than plastic labels and brewdog that i have come across always "float" off after being soaked for a day in a bucket of water (hot or icy cold, your choice) with a good 5 or 6 desert spoons of Sodium Percarbonate dissolved into it (Kettle of boiling water does the dissolving trick before topping bucket up).
A quick rinse under warm water with a cloth or scourer removes the dregs of the water based adhesive.
Plastic labels peel off, leaving some sticky residue. ###
Brewdog labels can be scraped off after the soak with a sharpish knife. ###
### Now the fun part, i "borrow" a bit of Ambersil Label remover from work and give the sticky residue a light squirt with this. Wait a couple of minutes, then give an old rag a spray with Ambersil and rub the sticky on the bottles and it does come off. The Ambersil has a strong Orange citrus smell, but a good wash of the bottle in soapy water and a rinse with clean gets rid, no problem.
Bit of a faff but no label has defeated me as of yet.... I dare them to try, around 400 ish bottles to date and i haven't been beaten.
