What Is Kahlua?

Kahlua is a famous coffee-flavored liqueur made from freshly brewed dark
roast coffee, sugar, vanilla beans, and rum or vodka. It’s smooth, creamy,
and delicious and goes great with coffee or vegan ice cream. Kahlua can
be served chilled or on the rocks and is often used in cocktails such as
white Russians or mudslides.

Homemade Kahlua brings back warm memories for me. Not that I got to drink it but I got to share the time with my mom while she made it.

Well, don’t get me wrong. I did get a sip and even at 16, I knew Kahlua was a special drink.

I have mom’s original recipe that is written on scratch paper – it is a bit dirty and I cherish it.

That recipe is now this recipe for everyone to have. Believe me, it’s been tried and tested many, many times.

For about 50 years. It’s that good and a real family tradition.

What liquor can I use to make Kahlua?

Rum is the tradition, and you can use dark rum or white rum. I like dark rum as I think it gives it more warmth.
Sometimes vodka is used, and that makes a nice Kahlua, too. It is easier on some people and doesn’t smell as strong. It makes a good cocktail.
There’s a liquor called Everclear. It’s powerful stuff and often used in creating liqueurs.
Brandy has also been used but that one needs to age about a month.

Do you have to use a vanilla bean to make homemade Kahlua

You don’t have to but it gives an aged quality but you only have to use an inch of the whole bean.
They are usually 5″ to 6″ long, so you can make a lot of Kahlua with one bean. That’s at least 2 gallons!
So the vanilla bean doesn’t sound so expensive when you look at it that way.
You can use a super good organic vanilla extract instead. The plus of this is that you can have instant gratification.
The Kahlua will still improve with time though but the vanilla bean recipe really makes it great.

Ingredients

Strong and hot fresh brewed coffee – gives depth to the sweetened rum.
Organic sugar – is the perfect addition to sweeten the alcohol.
Rum – is my favorite for Kahlua. Some people use Vodka.
Vanilla bean – This is necessary, but vanilla extract may be used. See the notes above if you use vanilla extract.

How to Make Homemade Kahlua

Measure sugar. Place organic cane sugar in a large mixing bowl.
Whisk in coffee. Add hot, freshly brewed, strong coffee to the bowl with the sugar. Whisk or stir until the sugar is completely dissolved, then allow the mixture to cool.
Add remaining ingredients and steep. Stir in rum and sliced vanilla bean. (If you are using vanilla extract instead, you’ll add this in the next step). Transfer the mixture to a jar or other lidded container, or simply use plastic wrap to cover the bowl. Seal tightly and allow the mixture to sit for 2 to 3 weeks in a cool, dry place.
Finish and enjoy! Strain the kahlua mixture to remove the vanilla beans and pieces. (If you opted to use vanilla extract instead of the vanilla bean, now is the time to stir it in! It won’t have quite the depth of flavor but it is good.) Transfer your homemade kahlua into a bottle that is easy to pour from and store. Pour over ice to enjoy!

How Long Does Kahlua Last?

Kahlua has a shelf life of about two years. The alcohol content acts as a
preservative, so the liqueur will last for a while. Once opened;
however, Kahlua will start to lose flavor after 6 months. Look at it if you’re unsure if your Kahlua has gone bad. If it has changed color, is starting to look cloudy, or has an unpleasant odor, then it’s probably time to toss it.
