This easy blackberry cocktail is about to be your summertime BFF. It's rich and earthy, but still refreshing: perfect for cocktail hour, brunch, or a lazy afternoon in the sunshine!

What you need for this blackberry whiskey lemonade:

Easy homemade blackberry syrup (we'll simmer fresh blackberries with a bit of sugar or honey and a splash of water, then strain the berry pulp out for a smooth syrup!)
Lemon juice (use real lemon juice here - not pre-made lemonade!)
Your favorite whiskey (we love a rich, spicy bourbon here!)
Fresh rosemary sprigs
Tonic water (you could also use club soda, soda water, or prosecco)
Plenty of ice!

Blackberries and sugar in a small pot, being cooked down into a thick syrup.

This is an easy whiskey cocktail to make at home: Just combine your ingredients, shake everything with some ice, and serve over more ice in a rocks glass (or a mason jar!)

Top if off with a splash of tonic water and a sprig of rosemary and you're good to go!

Use a cocktail shaker if you have one here: It's important to shake this blackberry lemonade cocktail to ensure all the ingredients are properly mixed. No cocktail shaker? Pour everything into a large mason jar, add some ice, then screw the lid on and shake!

How to make this blackberry cocktail for a crowd:

This is an easy cocktail to make in a big batch if you need to serve a crowd!

Make the blackberry syrup a day or two ahead of time. Store it in an airtight container in the fridge until you're ready to serve.
Juice your lemons in the morning before your guests arrive and store the juice in a mason jar in the fridge (you can use bottled lemon juice if you prefer, but it will taste much brighter with fresh lemon juice!)
Just before your guests arrive, combine the blackberry syrup, lemon juice, and bourbon in a large drink pitcher. Use a large whisk or immersion blender to whisk the mixture for a few seconds to incorporate the ingredients. Add a few sprigs of rosemary to the pitcher and store it in the fridge until you're ready to serve.
When you're ready to serve, pour the drink mixture into individual glasses filled with ice, top each serving with a bit of tonic water, and you're good to go! This whiskey lemonade will last in the fridge for 3-4 hours before it starts to lose flavor.

What kind of whiskey should I use for this cocktail?

Use any whiskey you like here!

We tend to reach for Elijah Craig Small Batch Bourbon for most of our whiskey cocktails: it's well balanced, not too expensive, and goes well with just about anything. If you like spicier, more booze-forward cocktails, you can use a stronger, spicier rye whiskey (we like Rittenhouse Rye for cocktail making!) You could also opt for an Irish whiskey here - our best advice is just to use a whiskey that you know you like!

If you're not a whiskey fan, this cocktail is also great with gin or vodka!

Description

A delicious blackberry whiskey lemonade cocktail perfect for summer entertaining.

Ingredients

Scale

FOR THE BLACKBERRY SIMPLE SYRUP:

12 ounces fresh blackberries
½ cup sugar
½ cup water

FOR THE BLACKBERRY WHISKEY LEMONADE:

8 ounces (1 cup) whiskey
8 ounces (1 cup) lemon juice
6 ounces (¾ cup) blackberry simple syrup (recipe above)
1 large rosemary sprig, plus extra for garnish
8 ounces (1 cup) tonic water

Instructions

FOR THE BLACKBERRY SIMPLE SYRUP:

Put the blackberries, sugar, and water in a small saucepan over medium heat. Stir to combine.
Cook, stirring occasionally, for 15-20 minutes or until blackberries have softened and syrup has slightly thickened (it should be thicker than water, but a little bit thinner than maple syrup).
Strain syrup through a mesh sieve to separate any seeds or lumps from the syrup. You can discard or compost the leftover berry pulp, but we like to freeze it in ice cube trays and pop a cube or two into smoothies.
Let syrup cool on the counter for 20 minutes before you make the drinks, or let it cool completely and store in an airtight container in the fridge for up to a week.

FOR THE BLACKBERRY WHISKEY LEMONADE:

Combine whiskey, lemon juice, blackberry syrup, and a sprig of fresh rosemary in a large cocktail shaker. Add a handful or two of ice cubes. Depending on the size of your shaker, you may have to shake the drinks in two batches.
Shake for 15-30 seconds to chill drinks and ensure all ingredients are combined.
Strain drinks into cocktail glasses filled with fresh ice. Top each drink with a splash of tonic water, garnish with a sprig of rosemary (optional), and serve immediately.

Notes

Additions and substitutions. Use honey in place of sugar for the blackberry syrup if you like. Use raspberries, strawberries, or blueberries in place of the blackberries if you prefer. Use vodka or gin instead of whiskey. Use frozen blackberries instead of fresh if you like (you will need to extend the syrup cook time by a few minutes). Omit the rosemary or use basil in its place. For a stronger rosemary flavor, add a sprig of rosemary to the blackberry syrup while it cooks. Use club soda, soda water, or prosecco in place of the tonic water if you like, or omit it completely.

What kind of whiskey should I use? We like using Elijah Craig Small Batch Bourbon for our whiskey cocktails. For a more booze-forward drink, you can use Rittenhouse Rye. Irish whiskey is also good here. Use whatever liquor you typically like to drink! If you're not a whiskey person, you can use vodka or gin instead of whiskey.

Make-ahead tips. Make the blackberry syrup a day or two in advance if you like. Strain out the berry pulp, let syrup cool completely, and store in an airtight container in the fridge until you're ready to use. If you're using fresh lemon juice, juice the lemons in the morning on the day you plan to make cocktails (any earlier and the flavor can start to change) and store in an airtight container in the fridge until you're ready to use.

To make this blackberry cocktail for a crowd, follow a 3:4:4 ratio (3 parts blackberry syrup to 4 parts each whiskey and lemon juice) and scale up as needed. For detailed instructions and a make-ahead timeline, be sure to read the post above.

If you don't have a cocktail shaker, use a mason jar with a tight-fitting lid instead.

Store extra blackberry syrup in the fridge for up to a week or in the freezer for up to six months.
