In a highball glass add 3 lime wedges (or other citrus if they fancy some fresh fruit), a pinch of sea salt and muddle.
Then add agave syrup to the glass. Fill the glass full of ice, add the White Claw Premium Vodka and top with a Ruby Grapefruit White Claw Hard Seltzer.
Stir and serve with a grapefruit slice and edible flowers, if desired.
