There’s something about a Lemon Gin and Tonic that just hits the spot—especially when the sun’s out and the day’s winding down. It’s light, crisp, citrusy, and comes together in minutes. This has been my go-to cocktail for summer nights on the porch, and over time, I’ve picked up a few tricks to make it even better. So, I thought I’d share one of my favorite after-work cocktails with you.

Lemon Gin and Tonic
What You’ll Need
Prep Time: 5 minutes
Servings: 1 cocktail
Glass: Highball or Collins glass
Ingredients
– 2 oz (60 ml) gin (London Dry gin works great)
– 1 oz (30 ml) fresh lemon juice (about half a juicy lemon)
– 4 oz (120 ml) tonic water, chilled
– Ice – enough to fill your glass
– Lemon slices – for garnish
Optional garnishes:
– Fresh rosemary sprig
– Cucumber ribbon
– A few fresh berries
Method
- Chill your glass. Pop your highball or Collins glass in the freezer for a few minutes, or fill it with ice water while you prep. A cold glass keeps your drink cool and refreshing longer.
- Fill the glass with ice. Use plenty—it not only chills the drink but keeps the tonic from going flat too fast.
- Pour in the gin. Measure out 2 oz (60 ml) and pour it right over the ice.
- Add lemon juice. Squeeze half a lemon for about 1 oz (30 ml) of juice. Strain out the seeds and pour it in.
- Top with tonic water. Slowly pour in 4 oz (120 ml) of chilled tonic water. Pour gently to keep the bubbles from fizzing out too quickly.
- Stir gently. Use a long spoon to give it a quick mix—just enough to combine the flavors without losing the fizz.
- Garnish and serve. Add a lemon slice or two. For something a little extra, toss in a sprig of rosemary or a cucumber ribbon.
Tips for the Best Lemon Gin and Tonic
- Use fresh lemon juice—bottled juice just doesn’t have the same brightness.
- Pick a good tonic. A quality tonic water makes a big difference. Fever-Tree or Q Tonic are great choices, but any brand you love will work.
- Go easy on stirring. Overmixing can flatten your tonic and dull the flavors.
Make-Ahead Notes
You can pre-squeeze lemon juice and store it in the fridge for up to 2 days. Keep your gin and tonic water chilled so you don’t have to rely on too much ice, which can dilute the drink.
Storage
This cocktail is best enjoyed fresh. If you’re batching for a group, mix the gin and lemon juice ahead of time, then add tonic and ice just before serving.
Serving Suggestions
Pair your Lemon Gin and Tonic with:
– Grilled shrimp or scallops – the citrus cuts through the richness beautifully.
– Light salads with citrus vinaigrette – keeps things fresh and vibrant.
– Herbed grilled chicken – the smoky flavor balances the bright drink.
Recipe Variations
Herbal Lemon Gin and Tonic
– Add a sprig of rosemary or thyme to the glass for a savory aroma.
– You can even lightly bruise the herb before adding it to release more flavor.
Spicy Lemon Gin and Tonic
– Add a few slices of fresh jalapeño to the glass.
– Let it steep for a minute or two for a little heat.
Berry Lemon Gin and Tonic
– Muddle a few fresh raspberries or blackberries in the bottom of the glass before adding ice.
– Strain if you want a cleaner look, or leave the fruit in for a pop of color and flavor.
Mocktail Version
– Skip the gin.
– Use tonic water or soda water with lemon juice and garnish.
– It’s bubbly, citrusy, and super refreshing without the alcohol.
Substitutions
– Gin: Try vodka for a cleaner, milder profile.
– Lemon juice: Lime juice works too—it’s a little more tart.
– Tonic water: Swap in soda water for less bitterness, or try flavored tonic for a twist.
Common Pitfalls to Avoid
– Flat tonic water: Always use freshly opened tonic. Once it’s flat, it loses its sparkle.
– Too much lemon: Balance is key. Too much juice can overpower the gin.
– Over-stirring: This can knock out the bubbles and make your drink taste dull.
Why It Works
This cocktail is all about balance—botanical gin, bright lemon, and crisp tonic. The lemon not only adds tartness but also enhances the aromatics in the gin. The carbonation from the tonic lifts the flavors and keeps the drink lively.
FAQs
Can I use lime instead of lemon?
Yes! Lime gives a tangier flavor and works just as well.
What type of gin is best?
A London Dry Gin is a classic choice—it’s clean and crisp. But feel free to experiment with floral or citrus-forward gins for something different.
Can I add other fruits?
Absolutely. Berries, cucumber, or even a slice of orange can be fun and flavorful.
How do I make it less bitter?
If tonic is too bitter for your taste, try a splash of soda water or a touch of simple syrup to soften it.
What’s the best garnish?
Lemon slices are classic. But rosemary, mint, or cucumber can add a refreshing twist.
Final Sips
A Lemon Gin and Tonic is one of those drinks that’s endlessly simple but feels a little special. Whether you’re relaxing solo or serving a round to friends, it’s a cocktail that always delivers. Try it once, and you’ll probably find yourself making it again and again—I know I have.
