In a cocktail shaker or measuring glass, combine the Empress 1908 gin, the lavender simple syrup, and handful of ice.
Stir to both combine and chill the ingredients.
Strain into a lowball glass filled with ice.
Top off the rest of the glass with tonic water & watch the color change before your eyes.
Add a small splash or squeeze of grapefruit juice.
Stir again before enjoying.
Notes
You can find a super simple lavender syrup recipe here.You can make the Lavender Empress using a different gin and it will still be light and floral. Just know it won't taste the same because Empress1908 truly is unique.
