In a shaker, add the honey, elderflower liquor, and grapefuit juice along with ice and shake vigorously so all the ingredients are well-combined and frothy.
Slowly top with gin so it creates a separate layer.
Next, slowly top with sparkling rose. It will blend with the gin and create a pretty lavendar color.
When ready to drink, gentlt stir with a spoon or straw so all the flavors are mixed.
Sip and enjoy!
You can buy unsweetened fresh grapefruit juice or you can squeeze fresh grapefruit juice yourself. Just make sure it is unsweetened or it will make the drink too sweet.
