You are probably right, I just read that on a Grenada blog somewhere years ago. I was planning on going down to Grenada next year but had such a good time on Salt Cay last week that we will be going back for the foreseeable future.

I just did some more research and it's anything over 70% ABV is prohibited. Why you'd want that anyway is beyond me.
I do have a funny story on Salt Cay where the local fire captain (not a busy job on an island of 100 permanent residents) burned down his golf cart. He's a drunk to start and the current story was he was heavy into the Haitian moonshine and the container was leaking. Right below the seat on the cart is the muffler and we were told thankfully he wasn't sitting in it or he probably would not have been in any condition to get out in time. The packs of condoms were still sitting in the ashes (they survived!?!? -we got pics), he was planning a party that night! They can't fire him (island politics and all) so they limit his duties.
