Vanilla Extract Calculator

How many vanilla beans and how much alcohol do you need for a batch of homemade extract? Tell the calculator the size of your container and it fills in the rest — the beans, the alcohol that fits alongside them, and the dates your batch will be ready.

Choose your strength: single-fold is standard grocery-store extract, 1.5-fold suits most home bakers, double-fold is for cookies, cakes, and ice cream, and triple-fold is the concentration professional bakers use. The calculator offers two formulas. We like the Co-op formula because it makes a slightly richer extract than the FDA minimum, but you can play around with it, adding a little less or a little more.

How Much Extract Does One Vanilla Bean Make?

One extract-grade vanilla bean weighs roughly 4 to 6 grams, and at the standard single-fold ratio it makes about 1 to 1.5 fluid ounces of extract — call it 6 to 9 teaspoons. Put the other way: a cup of finished single-fold extract represents about 5 to 7 beans.

Substituting extract for a bean in recipes

When a recipe calls for a whole vanilla bean and you want to use extract instead, the usual kitchen substitution is 1 whole bean ≈ 1 tablespoon (3 teaspoons) of pure single-fold extract. Using double-fold? Halve that. Going the other direction — swapping a bean in for extract — split and scrape it into anything you heat, like custards or ice-cream bases, where the seeds have time to infuse.

How the Math Works

The U.S. standard of identity for vanilla extract sets single-fold at 13.35 ounces of vanilla beans per gallon of at-least-35%-alcohol — that's the legal floor for anything sold as "pure vanilla extract," and it works out to 0.83 oz of beans per cup. The Co-op formula most home extract makers use rounds that up to a flat 1 oz per cup — about 20% richer, and extract-grade beans are inexpensive enough that the extra depth costs little. "Fold" is just a multiplier on the bean weight: double-fold uses twice the beans in the same alcohol. The calculator also sets aside room in the jar for the beans themselves — we allow about 2 ml per gram, which covers the beans plus a little headspace for shaking — so a 1-gallon container gets about 12.9 oz of beans and 0.81 gallons of alcohol at the Co-op single-fold ratio, not a full gallon of alcohol.

Alcohol matters less than people think — any 80-proof (40% ABV) spirit extracts well. Vodka is neutral; rum, bourbon, and brandy each tint the flavor. Below 70-proof, extraction slows and the batch risks spoiling. The waiting is the real ingredient: usable at 6 weeks, genuinely good at 3 months, at full depth from 6 months. In a hurry? Here's how to speed up vanilla extract — three ways to cut the wait.

Frequently Asked Questions

How many vanilla beans per cup of vodka?

One ounce of beans — roughly 5 to 7 extract-grade beans depending on size — per cup (8 fl oz) of vodka for standard single-fold extract. The FDA minimum is a little less, 0.83 oz per cup; the Co-op formula's 1 oz per cup makes a richer batch.

How much vanilla extract equals one vanilla bean?

In recipes, substitute about 1 tablespoon of pure single-fold extract for each whole bean. As a yield question, one bean makes roughly 1 to 1.5 fluid ounces of single-fold extract.

What alcohol should I use for vanilla extract?

Any 80-proof (40% ABV) spirit. Basic vodka is the neutral standard; rum leans sweet, bourbon warm and woody, brandy fruity. Avoid anything under 70-proof — the vanillin won't extract properly and the batch can spoil.

How long does homemade vanilla extract take?

Six weeks minimum for usable extract, three months for extract that's genuinely good, and six months or more for full depth. It keeps improving as long as beans stay submerged.

Should I use Grade A or Grade B beans for extract?

Grade B (extract-grade). Lower moisture and more vanillin per ounce than gourmet Grade A beans, so they extract more efficiently — and they cost less. Save Grade A for scraping into custards and ice cream.
