Flavoured vodka - fridge?

[cathkidstonbag]

Made a whole batch of these about a month ago and they are sitting in a dark room. But should I have refrigerated them?? They are in sterilised bottles/jars. Starting to worry I may give all my friends some kind of food poisoning for Xmas.....

As long as there's no cream in them, I think they should be fine. Putting them in the fridge is just for the enjoyment of the drink?

Mars bar in one of them but all the rest are boiled sweet type.
