Short answer: some of it leaves, not all of it, and anyone who tells you it all burns off is repeating something the published data does not support. The better question is why it is in the bottle at all. Alcohol is there because it is the finest carrier of aroma we have, which is the same reason it has been the backbone of perfumery for centuries.
- Alcohol is the carrier, and that is a design decision. It dissolves aromatic compounds water cannot touch, then releases them cleanly into the air where you can smell them.
- Aroma is most of what you call flavor. A carrier that moves aroma is not packaging. It is the delivery system.
- Some evaporates, some remains. How much depends on method and time, and heat alone does less than people assume.
- Assume none of it leaves and it still barely registers. A teaspoon of vanilla extract holds about as much alcohol as an inch and a half of a light beer, and that teaspoon flavors a whole batch.
- Fat based work is a different problem, and it has its own answer: an oil carrier, built for the job rather than substituted into it.
Alcohol carries aroma better than anything else we could put in the bottle
Open any bottle of perfume and you are holding aromatic compounds dissolved in alcohol. The alcohol is not a diluent and it is not a cost saving. It is volatile, so it lifts off and carries those compounds into the air where your nose can reach them. Take it away and the aroma sits there, sullen and closed. Perfumery settled this question centuries ago and has not revisited it.
Flavor works on the same physics, because most of what you experience as taste is actually smell. Your tongue contributes sweet, salt, sour, bitter and savory. Everything else, the vanilla, the rose, the cardamom, arrives through the back of your nose while you chew. That is why a cake baking fills a house and a photograph of one does nothing.
Food grade alcohol dissolves flavor compounds that water leaves behind, holds them in a stable solution that does not separate or degrade on the shelf, and releases them the moment the extract meets heat, fat or liquid. Nothing else available to a food manufacturer does all three as well.
That is why Culinary Aromatics® are built on an organic cane sugar alcohol carrier with no added water, and it is why the line is named for aroma rather than for taste.
It is also why the range includes a fine mist spritzer. You can aromatize a coffee, a cocktail glass, a plated dessert or a tasting flight at the moment it reaches the guest, putting aroma exactly where it does the most work and adding no moisture at all. We cover that whole approach in flavoring, aromatization, finishing and enhancement, and the carrier question itself in what carrier is in your flavor.
Perfumery settled this centuries ago. Flavor runs on the same physics.
Which is why vanilla extract is legally required to contain it
Under 21 CFR 169.175, the standard of identity for vanilla extract sets the alcohol content at not less than 35 percent by volume. Not as a maximum to be tolerated. As a minimum, below which the product is not vanilla extract.
That standard exists because the people who wrote it understood what makes vanilla extract work. A product below the threshold can be many things, but it cannot carry the name. So when you see a bottle marketed as alcohol free vanilla, read the front panel. It will say flavor, flavoring or essence, and it will be carrying the vanilla in something else.
Some of it leaves during cooking. Not all of it
The United States Department of Agriculture publishes retention factors for alcohol in cooked food, and they are not flattering to the folk wisdom. Heat alone does very little. Stirring an extract into a batter and baking it does not drive the alcohol off the way people picture. Time does more than temperature, and even a long simmer leaves a measurable fraction behind.
So the claim that it all cooks out is not true, and we would rather say so plainly than repeat something comfortable. The useful question is the one nobody asks next: a measurable fraction of what?
What it adds up to, next to a light beer
Take the least favorable assumption available, that not one drop leaves during cooking, and see where it lands.
| Alcohol it contains | |
|---|---|
| A 12 oz light beer, about 4 percent | roughly 14 ml |
| A teaspoon of vanilla extract, at the federal minimum of 35 percent | roughly 1.7 ml |
The whole teaspoon, undiluted and undivided, carries about one eighth of what is in a single light beer. Put another way, it is the alcohol you would get from about an inch and a half of the can.
And nobody drinks the teaspoon. It goes into a batch. If a recipe calls for a teaspoon and the finished batch serves twelve, one serving carries roughly one percent of a light beer. You would need to eat something like a hundred servings, in one sitting, to match one beer. That is before any allowance for the portion that does evaporate, which is real.
Multiply the volume of extract by its alcohol percentage. That is the alcohol that went in, assuming none leaves. Divide by the number of servings the batch yields.
Compare the result against 14 ml, which is roughly what a light beer holds. We would rather hand you the arithmetic than a reassuring adjective.
What alcohol free actually means on a label
Removing the alcohol does not remove the need for a carrier. Something still has to dissolve the flavor and let it go again. The usual substitutes are propylene glycol, glycerin or water, and each one costs you something.
Propylene glycol is the workhorse of the flavor industry and it appears on your ingredient statement. Glycerin is sweet, which shifts the balance of whatever you add it to. Water based systems need a preservation strategy, because water supports microbial growth that alcohol does not.
Four things we can state about every Culinary Aromatics® extract, each of which sits on a specification sheet rather than in a marketing line:
- No synthetic or artificial flavor ingredients.
- No propylene glycol.
- No added water.
- Built from the named botanical only, which is what keeps a with other natural flavors qualifier off a customer’s front panel.
Where an oil carrier is the better engineering choice
None of this makes alcohol the answer to everything. A carrier has to match the system it is going into, and fat based work is a genuinely different problem.
Our Pure Infusions™ flavor oils carry many of the same botanicals in an organic coconut derived MCT base. They are oil soluble and heat stable, which makes them the right tool for chocolate, ganache, compound coatings, icings, nut butters, dressings and anything else built on fat. That is not a compromise version of an extract. It is a different instrument, and in those applications it is the better one.
The reverse is equally true. An oil will not disperse through a batter, a syrup, a coffee or a cocktail, and an extract will. Choose by the system you are flavoring rather than by which carrier sounds preferable in the abstract. We put the two side by side in oil based versus alcohol based flavor.
There are also reasons to keep alcohol out that have nothing to do with performance. Some are religious, some are personal. For those, an oil based flavoring is the honest alternative, rather than an extract relabelled to sound like one.
Which format fits what you are making
Alcohol carrier, no added water. Disperses through batters, doughs, syrups, coffee, tea and cocktails, and sprays as a fine mist for finishing and aromatization.
Water based systems
MCT carrier from organic coconut. Oil soluble and heat stable, built for chocolate, confectionery, icings, nut butters and dressings.
Fat based systems
Both are Kosher PAREVE through Oregon Kosher, Non-GMO, Gluten-Free, and vegan, and both are produced in an NSF third party certified GMP and HACCP facility.
Madagascar vanilla is where most people arrive at this question. Our Pure Madagascar Vanilla Extract is made without propylene glycol, added sugar, or added water. For a full range, browse Culinary Aromatics® flavoring extracts, or the food grade flavor oils if you are working in fat.
Bakeries, roasteries, and beverage producers can order the same extracts in 1 gallon and larger sizes, with a certificate of analysis on every lot. Specification sheets are available on request through saenafoods.com.

Alcohol retention behaviour is described by the United States Department of Agriculture nutrient retention factors. The vanilla extract standard of identity is 21 CFR 169.175. Comparison figures use a 12 fl oz light beer at 4 percent alcohol by volume and a US teaspoon of extract at 35 percent.
