Wash one quart size mason jar or two pint size mason jars in warm soapy water, rinse, and allow to air dry.
Using a sharp paring knife, cut the vanilla beans in half lengthwise, leaving the top ½ inch of the bean uncut.
Place the vanilla beans in the mason jar (or divide between the two if using two jars) and top with vodka (dividing if necessary).
Screw the top on tightly, give the jar a shake, and store in a cool, dry place for 2-4 months, shaking once a week or so.
Use a funnel to transfer the vanilla to smaller amber glass bottles for long term storage.
1.) Swap the vodka for bourbon, brandy, or rum if desired.2.) You can add more vanilla beans to suit your taste.3.) If you would like to label your vanilla extract, print off my free PDF labels on sticker paper, cut out, and attach to your bottles.4.) You can reuse your vanilla beans by adding fresh vodka to the jar after transferring your extract to the amber bottles.
