So we bought some Grappa. It smells like jet fuel yet tastes a little like vodka. nice stuff. But there is no way we're going to be able to drive a fifth of it.

how long will it last once it's opened?

should it be refridgerated after opening?

besides using as a paint thinner or snow mobile fuel, what can i do with it besides drink it? can i use it in recipes that call for vodka or other liquors?
