The spooky season is here, and it’s the perfect time to mix up a festive cocktail. Whether you prefer gin, vodka, or a non-alcoholic mocktail, this Blackberry Widow is easy, flavorful, and fun to serve. It’s finished with sparkling Blackberry Spindrift for a bright, fizzy touch.

How to make this Halloween Cocktail
This blackberry Halloween cocktail is simple to prepare. The only real hands-on step is making the blackberry fall syrup — after that the drink comes together quickly. The syrup is gently infused with rosemary and whole cloves to add warm, autumnal notes that complement the berries without overpowering them.
To make the syrup, combine the brown sugar, water, blackberries, cloves, a sprig of rosemary, lemon zest, and a bit of lemon juice in a small saucepan. Bring the mixture to a low boil, then remove it from the heat and let it steep for 8–10 minutes so the flavors meld. Strain the syrup to remove solids so the final syrup is smooth and balanced.

After the syrup is ready, add fresh blackberries, the syrup, lemon juice, and your choice of spirit (gin or vodka) or a non-alcoholic substitute to a cocktail shaker or mason jar. Muddle the blackberries to release their juice, then add ice and shake until well chilled. Strain over crushed ice in a glass, filling about three-quarters full, then top with Blackberry Spindrift for a bright, sparkling finish.
How to make your Halloween Cocktail extra spooky
The garnish makes this drink memorable. A few blackberries and a rosemary sprig look lovely; for a smoky aroma, briefly char the tip of the rosemary and let it smolder for a moment before serving. For an eye-catching presentation, add a small chunk of dry ice to the glass just before guests arrive — handle dry ice with gloves and tongs and never touch or ingest it. The smoky, bubbling effect is a Halloween crowd-pleaser and elevates the cocktail into a theatrical experience.

Have fun with variations: swap in vodka if you prefer a cleaner spirit profile, or make a mocktail by replacing the alcohol with a sparkling elderflower lemonade (if it’s carbonated, add it at the end rather than shaking). If you try this Blackberry Widow, leave a rating and share how you served it — the syrup keeps up to two weeks in an airtight container in the refrigerator, though it’s best fresh.

Description
The Blackberry Widow is a refreshing Halloween cocktail that highlights blackberry flavor with warm fall spices and a bright citrus finish.
Ingredients
For the Blackberry Fall Syrup:
¼ cup light brown sugar
¼ cup water
8 fresh blackberries
3 whole cloves
1 fresh rosemary sprig
½ teaspoon lemon zest
½ teaspoon lemon juice
For the cocktail:
4 fresh blackberries, plus more for garnish
Crushed ice
0.5 oz blackberry fall syrup
0.5 oz freshly squeezed lemon juice
2 ounces gin (or vodka) — adjust or omit for a mocktail
4 ounces Blackberry Spindrift (or another sparkling berry soda)
Rosemary sprig, to garnish
Instructions
Make the Blackberry Fall Syrup:
In a small saucepan over medium-high heat, combine the brown sugar, water, and blackberries. Stir until the sugar dissolves, about 2 minutes, crushing the berries gently with the back of a spoon to release their juices. Add the cloves, rosemary, lemon zest, and lemon juice. Bring the mixture to a low simmer, then immediately remove it from the heat and let it steep for 8–10 minutes. Strain the syrup and set aside to cool.
Make the cocktail:
In a shaker or mason jar, muddle a few blackberries. Add the syrup, lemon juice, your choice of alcohol (or omit for a mocktail), and plenty of ice. Shake or shake in the jar until well chilled. Fill a serving glass with crushed ice and strain the cocktail over the ice. Top with Blackberry Spindrift, garnish with a rosemary sprig and extra blackberries, and serve.
Notes
*You can use vodka instead of gin. To make a mocktail, substitute sparkling elderflower lemonade or another non-alcoholic sparkling citrus drink; if the substitute is carbonated, add it at the end rather than shaking so it stays fizzy.
