From all indication on this forum and others - PET is not good for spirit storage. The alcohol leaches the plastics. Ok for beer due to the low alc %. Glass, kegs or barrels for storage. If using glass cookie jars make sure to remove the rubber seal.
I asked a while back whether a silicone seal (made from a baking tray) would be ok but not seen any response. similarly what about the rubber seals in a corny keg - no idea if it's safe or not - but I'm hoping it is as that's where I'm storing low wines.
