Make Your Own Watermelon & Basil Infused Vodka Recipe

Watermelon and basil infused vodka combines fresh fruit with an herbal note for simple summer cocktails. Add the ingredients to a clean jar, steep in the refrigerator, and strain when you like the balance. Serve it with club soda to let the infusion’s flavor come through, or use lemonade for a sweeter drink.

Allow roughly 3–5 days for steeping, checking the flavor along the way. The basil doesn’t have to stay in for the entire infusion: remove it sooner if its flavor starts to overpower the watermelon.

Ingredients

• 2 cups plain vodka
• 1 cup fresh watermelon chunks, rind and hard seeds removed
• 3 fresh basil leaves

Use fresh watermelon that tastes good on its own and basil leaves in good condition. Keep the watermelon in small chunks rather than blending it, which would leave more pulp to filter out. No sugar is added to this infusion; you can adjust sweetness later when mixing a drink.

You’ll also need a clean glass jar with a tight-fitting lid, a fine-mesh strainer, and a clean bottle or jar for storage. Choose a steeping jar roomy enough to hold the fruit and vodka with space to gently swirl the contents.

How to make the infusion

1. Prepare the fruit and basil. Wash your hands and clean your knife, cutting board, and utensils. Before cutting a whole watermelon, scrub its rind under running water with a clean produce brush, following the FDA’s produce-cleaning guidance. Rinse the basil and gently pat it dry. If using purchased cut watermelon, keep it refrigerated until preparation.
2. Combine the ingredients. Put the watermelon chunks and basil leaves in the jar, then pour in the vodka. Close the lid and label the jar with the ingredients and starting date.
3. Steep in the refrigerator. Refrigerate the jar throughout the infusion and gently swirl it occasionally. Use 3–5 days as a flavor guide, rather than a required minimum.
4. Check the balance. Periodically pour a small sample into a separate glass. If the basil is strong enough, remove the leaves with a clean utensil while the watermelon continues steeping. Don’t pour a tasted sample back into the jar. Tasting helps assess flavor, not food safety.
5. Strain and bottle. When you’re happy with the flavor, pour the infusion through a fine-mesh strainer and discard the solids. For less sediment, filter it again through a paper coffee filter. Transfer to a clean bottle or jar, close tightly, and refrigerate.

Simple ways to serve it

With club soda: Pour a measured serving over ice and top with chilled club soda. Start with a little soda and add more to suit your taste. A squeeze of lime is an optional finishing touch.

With lemonade: Substitute the infusion for plain vodka in a vodka lemonade. Taste before adding any extra sweetener, since the lemonade already supplies sweetness.

In a vodka cocktail: Try it in a familiar recipe that uses citrus and simple syrup. Make one drink first so you can adjust the citrus and sweetness without committing the whole batch.

If the herbal flavor is stronger than you wanted, blend a little of the infusion with plain vodka in an individual drink. This lets you adjust the flavor without changing the entire bottle.

Keep it refrigerated after straining

Store the finished infusion tightly covered in the refrigerator and keep its date label attached. N.C. Cooperative Extension recommends refrigerating or freezing infused alcohol, noting that fresh produce can introduce bacteria that alcohol may not kill.

This recipe has no validated storage life, so don’t assume it will keep as long as plain vodka or treat it as shelf-stable. Make it for planned use rather than long-term storage. Straining removes the fruit and leaves, but it does not establish that the drink is safe to store at room temperature.
