When I had my own place (rented) I built up a substantial collection of alcohols, however about 3 years ago I moved back to my parents to save towards a deposit and put everything in storage. I've managed to save enough and I'm looking for a place to buy. It won't be massive but I'll have room for my bottles again. My question is after 3 years will it all still be OK. It's all in boxes so not exposed to light. The vermouths are a write off, I have no idea why I bothered but I have loads of liqueurs like briottet, do you think they'll be OK to drink still.
