Grapefruit Rosemary Gin Fizz
Winter citrus is at its peak, and this Grapefruit Rosemary Gin Fizz is one of the easiest ways to bring bright, seasonal flavor into a classic cocktail. Freshly squeezed grapefruit juice, rosemary-infused simple syrup, and a clean, botanical gin come together in a drink that feels crisp and refreshing without being fussy. It’s a lovely option for winter gatherings, Friday evenings by the fire, or any night when you want a cocktail built around simple, seasonal ingredients.
Why I love this cocktail:
Grapefruit and rosemary are a natural match, especially in winter when citrus is abundant and rosemary is still thriving in the garden or greenhouse. The homemade rosemary syrup takes just a few minutes to prepare and keeps beautifully in the refrigerator, so you can mix this cocktail whenever the mood strikes. I also appreciate that this recipe doesn’t rely on specialty ingredients — a good gin, a splash of citrus liqueur, and a handful of ice are all you need. It feels fresh, bright, and versatile enough for both casual evenings and holiday gatherings.
How to make a Gin Fizz:

In a cocktail shaker with lots of crushed ice, combine gin, Grand Mariner, Pamplemousse and simple syrup. Shake until frosted over. Add in the fruit juices. Strain and pour over more crushed ice.
