Take a sturdy glass, like a rocks glass or a highball glass, and fill it with ice cubes. This will keep your drink chilled.
In a cocktail shaker or directly in the glass, muddle the fresh berries and lemon wedges. Use a muddler or the back of a spoon to gently crush the berries and release their juices. This step will infuse the drink with fruity flavor.
Pour 2 oz of vodka and 1/2 oz of simple syrup into the glass with the muddled berries and lemon. Adjust the amount of simple syrup to your taste preference; you can add more if you prefer a sweeter drink.
If you're using a cocktail shaker, cover it and shake the mixture vigorously for about 15-20 seconds. If you're mixing directly in the glass, use a spoon to stir the ingredients together until well combined.
If you prefer your drink without pulp or seeds, you can strain the mixture into another glass using a fine mesh strainer. This step is optional, depending on your preference.
Once your vodka, berries, and lemon are mixed, top the glass with soda water. This adds a refreshing fizz to the drink and helps balance the flavors.
Add a few fresh berries and a sprig of mint to garnish your drink. This adds a pop of color and a hint of freshness to your cocktail.
Your Berry Vodka Smash is now ready to be enjoyed! Serve it immediately and sip slowly to savor the delicious combination of flavors.
