Thyme Grapefruit Gin Sour

If you grow thyme and you’re not putting it in cocktails, why the heck are you growing thyme? And don’t tell me it’s for cooking or adding to chicken or something, because fresh thyme deserves better than that.

I grow all sorts of thyme in pots at my house throughout the year. Happily, in Southern California, it never really dies. It’s super versatile in cocktails, whether you are making a thyme simple syrup, muddling it in the glass, or using it as a garnish for that aromatic effect.

Here’s my Thyme Grapefruit Sour that I make when I want something herby, fresh, and a little more interesting than the usual gin sour without requiring a trip to a specialty store.

Why Thyme and Grapefruit Work So Well Together

Grapefruit has a natural bitterness that many citrus cocktails don’t have. Thyme is earthy and slightly savory with just a hint of floral flavor, so when you put the two together, they bring out the best in each other.

Lemon juice is just there to keep everything bright. It’s only 1/4 oz, but don’t skip it. Grapefruit alone can go a little flat, and the lemon is what keeps this drink crisp.

Make the Thyme Syrup First

You need thyme simple syrup, which only takes about 10 minutes to make and keeps in the fridge for a week, or you can freeze it in small 4 oz glass mason jars for a few months.

Two Recipe Twists to Try

Grapefruit Twist

When you squeeze and twist the peel of a grapefruit over the glass, the citrus oils release onto the surface of the drink. You smell it before you taste it, which brings the grapefruit forward even more.

Use a channeling knife to cut a long strip of grapefruit peel. Twist it over the glass, run it around the rim, then drop it in or drape it on the edge.

A fruit peeler works too if you want a wider, more dramatic strip.

A Bitters Twist

Want to push the citrus further? Add a couple dashes of grapefruit bitters to the shaker. It deepens the grapefruit flavor and adds a layer of complexity without changing the drink’s character.

A Few Notes Before You Shake

Fresh juice only. Bottled grapefruit juice works, but freshly squeezed is noticeably better. A citrus juicer is one of the most-used tools in my kitchen, and not just because I have a ton of citrus trees at my house.

Chill your glass. Pop the coupe glass in the freezer while you prep. A room-temperature glass warms your drink too fast.

Shake hard. 15 full seconds, minimum. For sours, you want the drink cold and properly diluted. If the shaker isn’t freezing cold in your hands, keep shaking.

Double strain. Pour through a fine-mesh strainer as you pour into the glass. It catches ice chips and gives you a cleaner pour.

Mocktail Version

Leave out the gin and you still have a lovely drink to sip or share with friends.

Mix grapefruit juice and thyme syrup to taste, top with soda water, and garnish with a grapefruit wedge. If you want something closer to the original, non-alcoholic gin will work, as it brings back some of the botanical quality the spirit adds.

Glassware

I use a coupe for all of my sours. The wide bowl shows off the color, and the garnish sits nicely on the rim. A Nick and Nora glass is a good alternative if you want something a little more delicate.
