Grapefruit Collins Recipe | Easy 5-Ingredient Gin & Soda Cooler

The Grapefruit Collins pours pale gold and bubbly, yet the first sip opens soft and fruity before snapping crisp at the finish. True to its name, it belongs to the Collins family, built on the same gin, lemon, sugar and soda formula as the Tom Collins, with pink grapefruit liqueur adding a gentle, rosy sweetness.

Dry gin brings the edge, generous lemon keeps it bright, and chilled soda lifts every sip. Light, refreshing and made for a hot afternoon, it is worth pouring tonight.

Grapefruit Collins Characteristics & Tips

Flavor & Characteristics

The Grapefruit Collins is a refreshing gin highball that brings fruitiness to the classic Collins formula of gin, lemon, sugar and soda. Pink grapefruit liqueur adds gentle sweetness on top of dry gin’s crisp edge.

The first sip opens with soft pink grapefruit, then lemon and soda tighten the finish. Gin’s botanicals and grapefruit’s slight bitterness echo each other, which keeps it bright rather than sweet.

It feels lighter than a Tom Collins, and I’d pour it first on a hot day as an aperitif.

Tips

  • Adjust the lemon to taste — This recipe uses a generous 1 oz (30ml) of lemon for a bright, tart edge. If you prefer it softer, drop to 2/3 oz (20ml), and the pink grapefruit’s sweetness comes forward.
  • Common mistake: shaking the soda — Adding soda to the shaker builds pressure and knocks out the bubbles, leaving the drink flat. Shake everything else first, then top with chilled soda in the glass.
  • Fill the glass with ice — Plenty of ice keeps the drink colder and slows melting, so it stays crisp to the last sip. I always fill a Collins glass to the top with ice for this one.

Twists

  • Fresh Grapefruit Collins — Swap the liqueur for 1 oz (30ml) of fresh pink grapefruit juice. You get a lighter, more natural citrus taste with a pleasant bitterness. Add a little more syrup if needed.
  • Rosemary Grapefruit Collins — Garnish with a fresh rosemary sprig instead of the lemon slice. Rosemary’s piney aroma is a classic match for grapefruit and links naturally with gin’s botanicals.

Food Pairings

  • Shrimp cocktail or ceviche — The drink’s bright citrus works like a squeeze of lemon over seafood, lifting the shrimp’s sweetness and keeping each bite fresh.
  • Avocado and grapefruit salad — Creamy avocado softens the drink’s tartness, while the grapefruit echoes its fruity aroma, a classic pairing that’s light and refreshing.
  • Herb-roasted chicken — Gin’s botanicals tie into the herbs, and the citrus cuts through the juicy, savory meat, keeping every bite light.
