The Organic Vanilla Bean Company has very reasonably priced beans, so you can make the best vanilla vodka vodka or extract you’ve tasted. 
By submerging a few beans in a bottle of reaonsable quality vodka (at home, we’ve used about 10/750ml bottle) for between 1 and 6 months, you will have an amazing vanilla vodka (you can also use other alcohol such as tequila or rum). Just keep your bottle in a fairly dark and cool area to keep it fresh.
After 6 months, the liquid will be quite dark and can now be used as vanilla extract. With a large number of beans such as we use, you can re-fill the bottle when it’s getting low and not lose very much flavour. I think we’ve probably refilled at least twice over and it’s still almost black and just as tasty as ever.
Play around, if you can. Citrus peels, cinnamon, and green cardamoms can all be added for a more exotic infusion.
