Interesting! Gin to me, imparts a "citrus-y" flavor, wonder how it will interact with the vanilla? (I bet it will be surprising and great)
What's the difference between the Madagascar and Mexican vanilla beans?
I tend to drink my gin/vodka/tequila/cognac before I remember that I could have used it to make vanilla extract.
Seriously, though, I'm really curious about using gin as your base. I used to think it was only good as a mixer in G&Ts, but have recently discovered it's great in many other...
