It might seem like a smart move to toss a spent vanilla bean into some alcohol to extract its remaining flavor, but buying pricey beans specifically for homemade extract is not the way to go. The reality is you lack the tools and technology needed to create a rich, flavorful, and intricate bottle of vanilla extract in your home kitchen.
We've all seen culinary enthusiasts boast about their 'DIY vanilla extract' by simply tossing vanilla beans into a jar of bourbon or vodka, but the truth is, they’re wasting both time and money. Vanilla contains over 400 flavor compounds—some dissolve in alcohol, others in water—and many can't be accessed using a simple, room-temperature extraction process.
As Stella Parks of Serious Eats points out in her insightful article on the topic (which you should definitely read), the process of making vanilla extract is more complicated than just tossing vanilla beans in alcohol and calling it done. Each company has its own method, but all require more than what a basic at-home setup can offer.
Cold extraction typically involves processing vanilla with various ethanol concentrations over a period of weeks or months, with each cycle designed to extract a different set of the 400+ flavor compounds found in vanilla. By adjusting the ethanol percentage with each round, a distinct flavor profile emerges. In the end, these individual extractions are blended to form the final product. Generally, cold extractions are known for producing a flavor that is more fruity and floral, sometimes with rum-like undertones.
Hot or pressurized extraction processes may involve similar techniques, but at varying temperatures and pressures, each chosen to pull out a different set of flavor compounds that will later be blended together. Some manufacturers may also use percolation to extract additional compounds. This method tends to yield a darker, more robust flavor with notes of caramel, dried fruit, or even oak.
In short, if you just toss vanilla beans into bourbon, you’ll end up with a nice, vanilla-scented bourbon, but you’ll miss the full spectrum of complex flavors from the beans. So, opt for a proper, professionally made vanilla extract (Stella has recommendations) and save the beans for times when you want to use the seeds in your baking. Afterward, you can throw the empty pod into some fernet or, even better, try one of Stella’s hot infusions. While you may not be able to control the pressure of your extraction, you can certainly experiment with temperature.
