Absolut - Graphene?

From an article on the Beeb about Graphene

Graphene is a form of carbon. It is a flat layer of carbon atoms tightly packed into a two-dimensional honeycomb arrangement.

 Dr Nair said: "Just for a laugh, we sealed a bottle of vodka with our (graphene) membranes and found that the distilled solution became stronger and stronger with time. Neither of us drinks vodka but it was great fun to do the experiment."

 Imagine the possibilities!
