Prepare your simple syrup. In a small saucepan, combine one cup of water, one cup of granulated sugar, and ⅓ cup dried culinary lavender. Bring to a boil then reduce to a simmer for 20 minutes. Let cool completely before straining the lavender from the syrup.
To prepare the glasses, combine the ground or chopped dried lavender with granulated sugar on a plate. Rim your glasses with lime juice from a lime wedge and invert into the lavender sugar.
For a single drink, combine grapefruit vodka, peach schnapps, lime juice, and simple syrup in a shaker with ice. Serve over ice in prepared glasses and top with grapefruit sparkling water.
For a pitcher, combine grapefruit vodka, peach schnapps, lime juice, and simple syrup in a pitcher. Stir to combine, then add grapefruit sparkling water and gently stir to combine. Serve over ice in prepared glasses.
