Homemade vanilla extract needs only two things: vanilla beans and 80+ proof vodka (80 proof equals 40% alcohol). The label on a commercial bottle may list water, alcohol, sugar and vanilla bean extractives; this version leaves the sugar out altogether and lets the beans steep in the spirit for at least 3 months.
The proportion is about 1 ounce of beans, or 6 plump ones, to each cup of vodka. That is slightly more than the U.S. standard for pure vanilla extract, which calls for at least 35% alcohol and roughly 0.83 ounce of beans per cup, so the finished extract can be used measure for measure in place of store-bought.
Vodka gives a neutral base, though rum or brandy can be used instead. Steep and store the extract in glass rather than plastic, ideally a dark blue or brown bottle, and keep the beans fully covered. A finished bottle can be kept going for years by topping it up with vodka as it is used and adding a fresh bean now and then.

Homemade Vanilla Extract
Ingredients
Method
- Cut each vanilla bean in half crosswise. Slit each piece lengthwise to expose the seeds, stopping about 1 inch short of one end so the two sides stay joined in the bottle.
- Put the beans in the bottle or jar, which should be glass, sterile and fitted with a lid that seals tightly.
- If using the commercial vanilla extract, pour it in, with a funnel if needed. It is optional and only serves to give the new batch a head start.
- Pour in the vodka. The beans must be completely submerged; trim any that stick out above the surface. For a bigger batch, keep to about 1 ounce of beans for each cup of vodka.
- Close the lid and shake the bottle.
- Keep the bottle in a cool, dark place for a minimum of 3 months, shaking it well about once a week. The extract darkens to a deep amber-brown, and its flavor keeps developing for up to a year.
