Grapefruit Gin Fizz

Grapefruit Gin Fizz is a refreshing twist on the classic cocktail, made with gin, grapefruit juice, and soda water for a crisp, citrusy sip.

The Grapefruit Gin Fizz is a light, bubbly cocktail perfect for warm days or easy entertaining.

Tart grapefruit juice pairs beautifully with the botanical notes of gin, while a splash of soda water adds that signature fizz. It’s a simple drink that feels a bit fancy, with a balance of sweet and sour that’s easy to customise to your taste.

Whether you’re hosting brunch or winding down on the patio, this citrus-forward cocktail is sure to impress.

Tips for Best Results

• Use fresh juice whenever possible – store-bought grapefruit juice tends to be more bitter and less vibrant than freshly squeezed.
• Balance the tartness: Grapefruit can be quite sharp. Start with the suggested amount of simple syrup and adjust to taste after shaking.
• Chill your glass before serving to keep your cocktail crisp and refreshing.
• Choose your gin wisely: A citrus-forward or floral gin complements the grapefruit beautifully. London Dry gin also works well for a cleaner finish.
• Optional froth: For a creamy variation, add 1/2 oz egg white and dry shake (no ice), then shake again with ice.
• Drink responsibly: This cocktail goes down easy, but it still packs a punch. Please enjoy in moderation and never drink and drive.

Ingredients and Substitutions

• Gin – Use your preferred gin; citrus or floral gins pair particularly well. Vodka can be substituted, but the flavour will be more neutral.
• Grapefruit Juice – Freshly squeezed pink or ruby red grapefruit juice is best for colour and balanced tartness. White grapefruit is more bitter but can be used if preferred.
• Lemon Juice – Adds brightness and sharpens the citrus profile. Lime juice could work in a pinch but will change the flavour.
• Simple Syrup – A 1:1 ratio of sugar and water. You can substitute with honey syrup or agave for a different sweetness profile.
• Club Soda – Adds the fizz. Sparkling water or soda water can be used interchangeably. Avoid tonic water – it adds unwanted bitterness.
• Ice – For shaking and serving.
• Optional Garnishes – Grapefruit wedge, twist, or a fresh herb like rosemary or thyme for aroma.
