Clean & dry your bottles very well.
Use a sharp knife to cut a slit in the vanilla bean, leaving just a little bit at the ends that you don't cut open.
Scrape some of the seeds from the inside of the bean to loosen a little into the bottle that you will be using, then put the beans whole into the bottle. Cover beans with Vodka (8oz to 5 beans, but make sure the Vodka covers the beans, you can cut the beans in half for smaller bottles).
Cover the bottle with lid, and attach label (make sure to label what kind of beans you used).
Shake for a few seconds.
Leave in a cold/dark place, and shake bottles every few days. Vanilla will be ready in 6 weeks (this is where the patience comes in haha). The longer it sits the darker and more flavorful it becomes, 6 weeks is the minimum.
Best part about this is, once you have made the vanilla, simply add more vodka to it once you use it, and the beans will continue to provide delicious vanilla extract!
