Add 4 fresh blackberries to a cocktail shaker or sturdy glass. Muddle the blackberries gently until broken down and juicy but not completely pulverized (about 10–15 seconds).

Add 6 oz Ole Smoky Blackberry Moonshine and 1 oz vodka (optional) to the shaker along with 0.5 oz fresh lime juice and 0.25 oz simple syrup.

Fill the shaker with ice (or add crushed ice if you prefer a slushier texture). Secure the shaker lid and shake vigorously for 8–10 seconds to chill and slightly dilute the drink and to help integrate the muddled berries.

Strain the mixture into the prepared glass filled halfway with crushed ice (use a fine strainer to remove seeds and larger pulp for a smoother drink).

Top with 2 oz club soda (or lemon-lime soda if you want sweeter and fizzier) and gently stir once or twice to combine without flattening the bubbles.

Add remaining fresh blackberries (if desired) to the drink for garnish and visual appeal, and place a lime wheel or wedge on the rim.

Serve

Serve immediately while cold. Offer a straw or long stirring spoon so the drinker can stir and release more blackberry flavor as they sip.

Tip: For a frozen variation, blend all ingredients (except club soda) with 1–1.5 cups crushed ice until smooth, then top with club soda and garnish.
