Homemade Vanilla Extract and Vanilla Sugar: How to Make Both

To make homemade vanilla extract, leave 10 g of split vanilla beans per 100 ml of 40% alcohol (that's 100 g per litre) to mature in the dark for at least 8 weeks. Over time, the alcohol draws vanillin and hundreds of other aromatic compounds out of the bean, giving a depth that synthetic vanillin can't match. The whole job takes five minutes – time does the rest.

Quick overview of the ratios:

• Beans: 10 g per 100 ml of alcohol = roughly 2–3 beans (one weighs 3–5 g).

• Alcohol: 40% vodka (neutral), or rum, bourbon or brandy – always at least 35%.

• Maturing: 8 weeks minimum, full flavor after 6–12 months, at room temperature and in the dark.

1. Split the beans lengthwise with a sharp knife, but leave them joined at the top. Don't scrape out the seeds – they stay in the extract and do their work there.

2. Cut them into pieces (3–5 cm / 1–2 in) if they won't fit into the bottle whole. They must be completely submerged.

3. Put them in a clean glass bottle and cover with alcohol – for 250 ml of alcohol, use 25 g of beans.

4. Seal and shake. For the first few weeks, give the bottle a shake once a week to help the extraction.

5. Store in the dark at room temperature (a cupboard or pantry) – not on a windowsill and not in the fridge. Cold slows extraction down, and light destroys aroma.

Within a few days you'll see the alcohol turn golden. It's ready when it's a deep amber, smells sweet and rounded, and the alcohol no longer overpowers the vanilla on your nose.

For 1 litre of alcohol, use about 100 g of vanilla beans – that's 10 g per 100 ml, or 25 g per 250 ml. This matches the US standard for single-fold pure vanilla extract: under the FDA rules (21 CFR 169.3 and 169.175), a gallon of extract contains the extractives of 13.35 ounces of beans in alcohol of at least 35% by volume – converted (378 g in 3.79 l), that's right around 100 g per litre.

Why weigh instead of counting beans? A single bean weighs roughly 3–5 g, depending on origin and moisture. For 100 ml you need 2–3 beans, and for 250 ml about 5–8 beans. With thin, dry beans, lean toward the higher number; with plump, moist ones, the lower. The standard assumes beans with a moisture content of no more than 25% – moist beans contain more water, so feel free to add a few grams extra.

• Fewer beans (say 2–3 per 250 ml) also works – you'll just get a weaker extract that takes longer to mature and that you'll need to use more of in recipes.

• Double-fold extract (200 g per litre, 20 g per 100 ml) is more concentrated – handy where you don't want to add much liquid, such as creams or ganache. Use half the amount in recipes.

You don't need to buy the prettiest beans for extract. Shorter, drier or slightly split beans (sold abroad as "grade B") smell just as good, and the alcohol doesn't care. You'll find vanilla of various origins in the vanilla beans and vanilla category – Ugandan is bold with milky-cocoa notes, Madagascar Bourbon is classically creamy, and Tahitian is floral and fruity. For how the types differ and what they cost, see the article Vanilla Beans: Types, Price and How to Use Them.

The best choice is plain vodka at 40% ABV – it's neutral, so the vanilla itself takes center stage. What matters is that the alcohol is at least 35%: that's the minimum the US FDA sets for vanilla extract (21 CFR 169.175). Weaker alcohol preserves the extract less well.

• Vodka (40%) – pure vanilla flavor, the most versatile choice.

• Rum (dark or light, 37.5–40%) – caramel and spice notes, great for Christmas baking and bundt cakes.

• Bourbon or brandy (40%) – woody, biscuity aroma that suits chocolate desserts.

• Stronger spirits (50% and up) – unnecessary; without water, some aromatic compounds are released from the bean less readily.

• Liqueurs and spirits under 35% – unsuitable, see the mistakes below.

Don't buy expensive alcohol, but don't buy the cheapest one with a harsh smell either – that smell will stay in the extract.

Vanilla extract is usable after 8 weeks at the earliest and reaches full flavor after 6–12 months. In the first weeks it smells mostly of alcohol, and only gradually does the aroma mellow.

As a rough guide:

• 2–4 weeks – the color is already dark, but the flavor is sharp and flat. Don't use it yet.

• 8 weeks – good for everyday baking.

• 6 months and more – a deep, sweet aroma you'll appreciate in vanilla custard or ice cream.

How to tell it's ready:

• Color: dark amber to brown, with soft, pliable beans.

• Smell from the bottle: your first impression is vanilla, not alcohol.

• Spoon test: put a few drops into a spoonful of warm milk or water. If you smell round, sweet vanilla with alcohol only in the background, it's done. If it stings, let it mature longer.

You don't have to start over each time: as you use up extract, top up with the same amount of alcohol and, for every 250 ml of alcohol you add, put in about 25 g of beans (used ones are fine). Leave the old beans in the bottle – they'll keep giving for months.

The used beans can even come from a custard, as described below – just rinse them. You can spot beans that are spent because they're pale, soft and barely smell – take those out and dry them for vanilla sugar.

Yes, you can make an alcohol-free vanilla infusion with food-grade glycerin diluted with water, roughly 3 parts glycerin to 1 part water, using the same ratio of beans (10 g per 100 ml). Expect two trade-offs, though:

• It's weaker. Glycerin draws out aromatic compounds more slowly and less fully than alcohol; vanilla producers say that even after 6–12 months of maturing, it stays behind an alcohol extract. Use more of it in recipes.

• It keeps for a shorter time. Glycerin preserves less well than alcohol – vanilla producers quote roughly 1–2 years, whereas alcohol extract lasts practically indefinitely. Store it sealed, somewhere cool and dark, and throw it out as soon as it turns cloudy, smells off or develops a film on the surface.

The result is sweeter and milder. If you don't need liquid vanilla, the simplest alcohol-free route is vanilla sugar.

Homemade vanilla extract made with alcohol of at least 35% lasts practically indefinitely if you store it tightly sealed, in the dark, at room temperature. McCormick states that pure vanilla extract has an unlimited shelf life; the alcohol the FDA requires in extract doesn't allow microbes to grow.

• Where: a dark cupboard or pantry, away from the stove and the window.

• Where not: the fridge – according to McCormick, moisture condenses in the bottle in the cold and the extract turns cloudy.

• In what: dark or clear glass with a tight closure; avoid plastic and metal lids without a seal.

• Sediment at the bottom: seeds and fine fibers from the bean, not spoilage. Shake the bottle before using.

• Beans in the bottle: they must stay submerged – anything poking above the surface dries out and may mold.

Store vanilla sugar in a dry, tightly closed jar; its only enemy is moisture, which clumps it together.

On a Czech label, you can recognize real vanilla by the words "vanilla extract" or "natural vanilla flavoring"; the words "flavoring", "vanillin" or "ethylvanillin" on their own mean the aroma doesn't have to come from a bean. Under the rules the Czech food inspectorate (SZPI) derives from Regulation (EC) No 1334/2008, a manufacturer may label a food "vanilla" only if the vanilla comes from natural vanilla flavoring, vanilla extract, or the bean and its pulp – with natural flavoring at a purity of at least 95/5. With ethylvanillin or a mix with other flavorings, it may only say "vanilla flavored" or "with vanilla flavor".

• Vanilla extract – an infusion of beans in alcohol (sometimes with sugar or glycerin). Exactly what you're making at home.

• Natural vanilla flavoring – an aromatic component from vanilla, at least 95% from vanilla beans.

• Vanilla paste – a thick extract with seeds and a thickener (sugar, syrup, gum). It gives you black specks like a bean.

• Flavoring / vanillin / ethylvanillin – a single aroma compound, usually made synthetically; this is what vanillin sugar smells like.

How much extract replaces one bean: 1 vanilla bean ≈ 1 tablespoon (15 ml) of single-fold extract ≈ 1 tablespoon of vanilla paste. With double-fold extract, 1½ teaspoons (7–8 ml) is enough; with a weaker homemade one, add a little more and go by the smell of your batter or cream. For more substitutes and exact ratios, see the article What Can You Substitute for a Vanilla Bean.

To make vanilla sugar at home, bury 1 vanilla bean in 250–500 g of sugar in a tightly closed jar and let it sit for 1–2 weeks. The sugar absorbs the aroma, and the bean keeps going in it until the sugar runs out.

A faster, more intense version:

1. Split the bean lengthwise and scrape out the seeds with the back of a knife.

2. Rub the seeds into the sugar with your fingers – they break up and spread evenly (otherwise they stay in clumps).

3. Cut the scraped bean into pieces and bury them in the sugar.

4. Seal and shake. With the seeds rubbed in, the sugar is usable almost immediately and has its full aroma after a week.

With 250 g of sugar and one bean, you get a bold sugar for coating; with 500 g, a milder one for everyday baking.

You can make vanilla sugar from granulated or powdered sugar: granulated is hardier and doesn't clump. Powdered sugar absorbs the aroma faster but picks up moisture easily – keep it dry and sift it before use. Vanilla powdered sugar is exactly what you need for coating vanilla crescent cookies.

To make vanilla sugar from used beans, rinse the bean, dry it completely (1–3 days in the open air, or 10–15 minutes at 60–80 °C / 140–175 °F), then bury it in sugar or blitz it with sugar, about 1 bean per 100–200 g. A used bean – say, after making pudding or custard, or after infusing in extract – still has plenty of aroma for vanilla sugar. You just have to dry it completely first, otherwise the sugar will get damp and clump.

1. Rinse the bean (to remove milk or cream) and pat it dry with a paper towel.

2. Let it air-dry for 1–3 days at room temperature, or put it in the oven at 60–80 °C (140–175 °F) for 10–15 minutes. It's ready when it's hard and snaps.

3. Either bury it whole in sugar, or blitz it together with the sugar (about 1 bean per 100–200 g) in a blender or coffee grinder and sift out the tough fibers.

Blended sugar from dried beans is the strongest version – dark-flecked, intensely fragrant, and made from bean "leftovers".

Vanilla sugar is flavored with real vanilla (beans, seeds or extract), while vanillin sugar is flavored with a synthetic flavoring – vanillin or ethylvanillin. Vanillin is the main aroma compound in vanilla, but on its own it's just one note – real vanilla has hundreds, which is why it smells fuller, creamier and less "candy-like".

Store-bought vanillin sugar is cheap, and in baking with other strong flavors (cocoa, spices, gingerbread) you often can't tell. You'll notice the difference mainly where vanilla plays the lead: in crescent cookies, whipped cream, custards or vanilla ice cream. That's where homemade vanilla sugar or extract pays off most. To see exactly where the difference shows in Christmas cookies, read Vanilla Sugar or Vanillin Sugar.

A single vanilla bean can serve you three times: first the seeds go into a custard, then the bean into extract, and finally the dried bean into sugar.

1. For custard: scrape the seeds into a cream, pudding or batter; simmer the bean in the milk.

2. Into extract: drop the rinsed bean into a bottle of extract – it adds to its strength.

3. Into sugar: dry the bean you've steeped in extract and blitz it with sugar.

Store unused beans so they don't dry out – you'll find how in the article How to Store Vanilla Beans So They Stay Plump and Fragrant.

For Christmas, start your vanilla extract by the end of October at the latest (8 weeks before Christmas Eve), ideally at the start of October; vanilla sugar is fine to make at the start of December, 1–2 weeks ahead. The extract keeps maturing at the recipient's home, so a younger bottle is no problem – just note when it's ready to use.

How much to make:

• Extract as a gift: a 100 ml bottle = 10 g of beans (2–3 beans). From 500 ml of vodka and 50 g of beans, you can fill 5 little bottles. Add a piece of bean to each and a label with the start date.

• Vanilla sugar as a gift: a jar with 250 g of sugar + 1 bean with the seeds rubbed into the sugar.

• Vanilla sugar for coating crescent cookies: for one batch of crescents, count on roughly 150–200 g of powdered sugar with 1 bean (rubbed-in seeds + chopped bean), so you have enough for a double coating. Coat the cookies while they're still warm.

To make the cookies taste of vanilla all the way through, the right flour and nuts help – see Vanilla Crescent Cookies: Which Nuts and Flour to Use. And for more ideas on what to give from your kitchen and how to wrap it, see Christmas Food Gifts from Your Kitchen.

Most failed attempts come down to one of six causes: too few beans, weak alcohol, impatience, beans above the surface, a damp bean in the sugar, or light and heat.

• Too few beans. One bean in a half-litre bottle gives you vanilla vodka rather than extract. Stick to 10 g per 100 ml (100 g per litre).

• Alcohol under 35%. Weaker alcohol preserves the extract less well, and it may spoil over time.

• Impatience. After 3 weeks the extract is dark, but the flavor isn't there yet. Color doesn't mean it's done.

• Beans above the surface. Whatever sticks out of the alcohol dries out and may mold. Cut the beans shorter.

• A damp bean in sugar. A freshly used bean from a custard adds moisture to the sugar – it hardens and, in the worst case, starts to ferment. Always dry it first.

• Light and heat. A bottle on a windowsill or above the stove loses aroma. A dark cupboard is ideal.
