A classic greyhound cocktail made with gin and fresh grapefruit juice. It's crisp, refreshing, and one of the simplest cocktails you can make. Use ruby red grapefruit for the best flavor and color.
Garnish with a slice of grapefruit and a sprig of rosemary.
Notes
Both US customary and metric measurements are provided.
Use freshly squeezed grapefruit juice for the best flavor. Bottled juice tastes flat in comparison.
Ruby red grapefruit is sweeter and gives the cocktail a beautiful pink color. White or pink grapefruit will work but will be more tart. Add a dash of simple syrup if needed.
Gin is the original spirit in a greyhound and my preference, but you can swap it for vodka for a cleaner, more grapefruit-forward drink.
For a salty dog, rim the glass with salt before adding the ice.
A flavored simple syrup like rosemary or thyme makes a lovely addition if you want a little extra depth.
