I asked the same question a while back and got lots of replies from forum members and suppliers. I came up with putting everything in glass dark bottles and storing them in a wine chiller at about 50 degrees. The nicotine can be frozen, but the food flavoring cannot. I can't remember why the wine chiller came up, but it is smaller and cheaper than a dorm fridge. I think I may have been thinking about storing juice and nic base and a dorm size fridge with the ability to set 2 temps was many times more expensive than the wine chiller.
