Let’s talk about how to make vanilla extract with rum!
Making homemade vanilla extract takes just a few minutes of hands-on time, and adding rum gives it an incredible depth of flavour — perfect for cakes, cookies and cocktails.
Vanilla has a way of enhancing other flavours — like a smooth canvas that lifts everything you add. Good-quality extracts can be expensive, but if you can find alcohol at a reasonable price and have access to vanilla beans, making your own can be far more economical.
This method is simple, and I’ll share tips for choosing beans and alcohol, plus why I like to add rum for a richer, more rounded extract.

Vanilla Extract Ingredients
There are only a few ingredients: vanilla beans and alcohol. Read on for guidance on bean grades and alcohol choices.
What kind of vanilla beans should I use?
I prefer “Grade B” or “extract quality” beans for extract. They’re drier and often less visually perfect than Grade A, which makes them more affordable, but they hold just as much flavor. Once steeped in alcohol they rehydrate and release their aroma and taste.
Different vanilla species have subtle flavor differences, so feel free to experiment. All are delicious; choose what you enjoy and what’s available locally.
What is the best alcohol for vanilla extract?
The classic base is vodka for a clean, pure vanilla flavor. Vodka is neutral and lets the vanilla shine. If you want extra depth, add rum. I usually combine vodka and rum to balance pure vanilla with sweet, caramel notes from the rum.
Rum
Rum brings sweet, almost caramel-like notes because it’s distilled from sugarcane byproducts like molasses. Choose a dark or gold rum; white rum lacks the same depth. Spiced rum can work but may mask delicate vanilla notes.
If you use only rum the spirit’s flavor can dominate, so I recommend a mix: roughly one part rum to three parts vodka for balance.
Any decent-quality vodka and rum will do — check the alcohol content on the bottle: around 37–40% ABV is good. Very cheap vodkas sometimes have lower alcohol content and won’t extract as well.
To keep costs down, buy alcohol on sale or pick it up duty-free when you travel. That can cut your homemade extract’s price significantly.
You can also experiment with bourbon or whiskey in place of rum for different, warm flavor notes.
How to make vanilla extract with rum
You’ll need a glass bottle of about 1 litre — an empty vodka bottle works fine. A swing-top bottle looks nicer for gifting, but any clean, airtight glass bottle will do.
Split each vanilla bean lengthwise, leaving one end attached so they’re easy to pull out later. If you want visible seed specks in your baking, scrape the seeds into the bottle; otherwise just split the pods and add them whole. A few seeds will escape and settle to the bottom — that’s flavor, and you can strain or decant later if desired.
Fill the bottle about one quarter full with dark or gold rum. Place the split beans into the bottle with the split ends down, then top up the bottle with vodka until full.
Push the beans in so they’re submerged, wipe any seeds from the rim, seal the bottle, give it a good shake and store it in a cool, dark place.
Shake the bottle whenever you remember — ideally about once a week — to help extraction. After bottling, label it with the date so you know when to start checking the flavor.
Store in a cool, dark spot and shake occasionally. Now comes the waiting.
How long does vanilla extract need to steep?
Some sources say six weeks is enough, but I find the vanilla is much better after a longer rest. Minimum two months is a good guideline; check the bottle and if vanilla is the dominant aroma, it’s ready. I prefer 4–6 months for the richest flavor.
If you give extract as a gift before it’s fully matured, add a note with the date it will be ready.
I maintain a rotation: make a new bottle every six months so there’s always a matured bottle ready when another runs out. It’s easy enough to do regularly.
Over time the alcohol darkens as it extracts color and flavor from the beans — that color is a sign of extraction and flavor development.
Quick vanilla extract FAQ
Store it in a cool, dark place. Keep it somewhere visible so you remember to shake it occasionally, or set a calendar reminder.
The recipe is gluten-free by ingredient. Distilled spirits like vodka typically do not retain gluten after distillation; rum is made from sugarcane and is naturally gluten-free. Vanilla beans are gluten-free as well.
Alcohol-based vanilla extract is effectively preserved by the alcohol and can last indefinitely. I typically use mine within a year or two because I bake a lot, but it won’t spoil like perishable food.
Used beans can be repurposed. Add them to a new batch alongside fresh beans to extend flavor, or dry them and make vanilla sugar: dry thoroughly (oven or dehydrator), then store with sugar in an airtight jar for a week or two to infuse.
Technically yes: it’s alcohol flavored with vanilla. Use it in cocktails or add a splash to a soda for a grown-up vanilla drink, but remember it’s concentrated and meant primarily for flavoring food and drinks in small amounts.
