Homemade vanilla extract is made using just two ingredients: vanilla beans and alcohol. The most common choice is vodka, but other spirits like bourbon, rum, or brandy can also be used. The process involves splitting the vanilla beans to expose their seeds, then submerging them in alcohol to extract their flavor.

Once you combine the vanilla beans and alcohol, patience is key. The minimum time for the flavors to develop is about two months, but for optimal flavor, it’s recommended to let it sit for four to six months. Some enthusiasts even wait up to a year to achieve a richer taste (source: Going Zero Waste, Sally's Baking Addiction).

When made correctly, homemade vanilla extract can last for 5 to 10 years. The longevity depends on storage conditions, such as keeping it in a cool, dark place away from direct sunlight (source: Going Zero Waste, Sugar Spun Run).

Storage Conditions:

Store your vanilla extract in a glass bottle with a tight seal. Amber bottles are ideal as they protect the extract from light degradation.
Keep it in a cool, dark place, such as a pantry or cupboard.

Quality of Ingredients:

Using high-quality vanilla beans and alcohol can enhance the flavor and longevity of your extract. Grade B vanilla beans, which are specifically meant for extraction, are often recommended for their rich flavor (source: Bon Appétit).

Refilling the Extract:

As you use your homemade vanilla extract, you can top it off with more alcohol. This practice helps maintain the flavor profile, but over time, the original beans will lose potency. It’s suggested to replace the beans after about a year of frequent use (source: Sally's Baking Addiction).

Shake Regularly: Shake the bottle every few weeks to help the flavors meld and develop.
Monitor for Quality: If the extract still smells fragrant and has a rich color, it is likely still good to use. If it develops an off-smell or unusual appearance, it’s best to discard it.
Reuse Vanilla Beans: You can reuse vanilla beans for subsequent batches of extract, but the flavor will diminish with each use. Most recommend using them no more than four times (source: Going Zero Waste).

Homemade vanilla extract is not only a delightful addition to your culinary repertoire but also a sustainable and economical choice. With a shelf life of 5 to 10 years when stored properly, it’s a pantry staple that keeps on giving. By understanding the factors that influence its longevity and following best practices for storage, you can enjoy the rich, authentic flavor of homemade vanilla extract for years to come. So, start your batch today and savor the difference in your baking!
