The Southside: A Fresh Gin Cocktail Worth Mastering
The Southside is a gin sour built on London dry gin, fresh lemon juice, simple syrup, and mint leaves, shaken hard over cracked ice and strained into a chilled coupe. It tastes crisp, herbal, and lightly tart. You can make it in about 3 minutes and it serves one.

The Southside is what happens when a gimlet grows up and gets a garden. It's a gin sour, sure, but the mint changes everything. Where a gimlet is all sharp citrus and clinical precision, the Southside brings a green, herbal freshness that makes it dangerously easy to drink. You get the juniper of the gin, the tart snap of lemon, and that cool mint finish that lingers just long enough to make you want another sip. This version uses a London dry gin, which gives you that classic piney juniper backbone. Skip the fancy artisanal stuff for this one. You want something clean and assertive that won't get lost behind the lemon and mint. The whole thing comes together in about three minutes of actual work, most of which is just getting your ice and glass ready. It's the kind of drink that works equally well at a summer barbecue and a dim bar on a Tuesday night.
About the Southside
The Southside's origins are murky, which is typical for a Prohibition-era cocktail. The most persistent story ties it to the Southside Sportsmens Club on Long Island, a hunting and fishing retreat where wealthy New Yorkers escaped the city. Another version credits a 1920s Chicago gangster with the name, though there's no solid evidence for either claim. What's certain is the drink belongs to the sour family, sitting alongside the gimlet, the daiquiri, and the whiskey sour. Its defining feature is the mint, which sets it apart from those simpler citrus drinks. The Southside gained a following in the mid-20th century as a refined alternative to the mint julep, offering a similar herbal freshness without the bourbon or the crushed ice theatrics. Today it's a menu staple at craft cocktail bars, appreciated for its balance and its ability to showcase a good gin.
Why it works
- 1The hard shake aerates the mint's volatile oils, releasing their aroma without tearing the leaves into bitter shreds.
- 2London dry gin's juniper-forward profile stands up to the lemon and mint instead of disappearing behind them.
- 3The 1:1 simple syrup balances the lemon's acidity so the drink reads tart rather than sour.
- 4Double straining removes tiny ice shards and mint fragments, leaving a silky, crystal-clear drink.
- 5The cold coupe glass keeps the drink at the right temperature from the first sip to the last.
Ingredients
Serves 1.
2 oz London dry gin, a London dry style works bestIts juniper-forward profile holds its own against the lemon and mint.
1 oz freshly squeezed lemon juice, freshly squeezedBottled juice has a flat, metallic taste that ruins the drink.
1 oz simple syrup, 1:1 sugar to waterA 1:1 ratio gives you sweetness without the syrupy weight of a rich syrup.
5 leaves mint leaves, plus one sprig for garnishSpearmint is the classic choice; its oils release easily with a gentle muddle.
2 dash Angostura bittersAdds a subtle spice backbone that rounds out the citrus and mint.
ingredients
The gin matters most here. Pick a London dry like Beefeater, Tanqueray, or Bombay Sapphire. They're juniper-heavy, which is exactly what you want. For the lemon, roll it on the counter before juicing to get more juice out. And for the mint, look for spearmint with bright green leaves and no dark spots. Skip the muddled mint if you only have older, wilted leaves; they'll turn bitter and ropey in the shaker.
You need: jigger or measuring spoons, cocktail shaker, strainer, muddler, fine strainer.
Method
Chill your coupe
Fill your coupe glass with ice or put it in the freezer for a few minutes. A cold glass keeps the drink from warming up too fast after you strain it in. You can skip this if you're in a rush, but the drink will suffer for it.
Look for: The glass feels cold to the touch and frosts slightly on the outside.
Common mistake: Using a warm glass. The drink warms within seconds, and the mint's freshness fades fast.
Drop the five mint leaves into the bottom of your shaker. Add the simple syrup and a dash of the bitters. Press down gently with the muddler, just two or three twists. You want to release the oils, not pulverize the leaves into a green paste.
Look for: The leaves are bruised and darker in spots, but still whole. A thin film of syrup pools around them.
Common mistake: Muddling too hard. You'll tear the leaves and extract bitter chlorophyll, which makes the drink taste vegetal and harsh.
Pour in the gin and the fresh lemon juice. The lemon juice goes in after the syrup because it stops the mint from oxidizing further. The bitters join the party here too, the remaining dash.
Look for: The liquid in the shaker is a pale, cloudy yellow-green from the lemon juice and mint oils.
Common mistake: Adding the mint after the alcohol. The high-proof gin will 'burn' the leaves and make them taste bitter.
Fill the shaker with cracked ice. Not one big cube, but smaller pieces. Seal it and shake hard for 10 to 12 seconds. You're not just chilling the drink; you're aerating it and diluting it just enough to soften the alcohol burn.
Look for: The outside of the shaker frosts over. When you hold it, it's almost too cold to touch comfortably.
Common mistake: Shaking too long or too gently. Over-shaking over-dilutes and flattens the mint. A weak shake leaves the drink too strong and sharp.
Discard the ice from your coupe. Hold the fine strainer over the glass and pour the drink through both the shaker's built-in strainer and the fine mesh. This catches the tiny ice shards and any bits of mint leaf that would cloud the drink.
Look for: The liquid runs clear into the glass, a pale straw color with no visible particles or ice chips.
Common mistake: Skipping the fine strainer. Shards of ice will dilute the drink further as it sits, and mint fragments will float to the top and turn bitter.
Slap the mint sprig against your palm to release its oils, then rest it on the edge of the glass or float it on top. The aroma should hit you before the glass touches your lips.
Look for: A bright green mint sprig sits on the rim, and the drink smells fresh and herbal, not sharp or boozy.
Common mistake: Dropping the sprig in without slapping it. The oils stay locked in the leaf, and you lose the aromatic hit that makes the drink so good.
Tips from the bar
- 1Use a jigger, not a free pour. The balance of this drink is delicate, and a quarter ounce off on the lemon or syrup changes the whole character.
- 2If your mint is looking tired, soak it in ice water for five minutes before use. It perks right back up.
- 3For a slightly sweeter version, bump the simple syrup to 1.25 ounces. It's a small change that makes the drink more approachable.
- 4Try a navy-strength gin for a boozier Southside. The higher proof holds up even better against the lemon and mint.
- 5To make simple syrup, dissolve equal parts sugar and water over low heat. Let it cool before using.
Variations
- The Eastside: Muddle in a few slices of cucumber along with the mint for a cooler, more vegetal version.
- The Southside Royale: Top the finished drink with a splash of champagne or sparkling wine for a festive, bubbly twist.
- The Bourbon Southside: Swap the gin for a high-rye bourbon. The mint and lemon work beautifully with the vanilla and oak notes.
- The Spicy Southside: Add a thin slice of jalapeño to the shaker before you muddle. It infuses a gentle heat that plays well against the mint.
Substitutions
- No mint? Use fresh basil or Thai basil. The flavor is more peppery, but the effect is similar.
- No lemon juice? Lime juice makes a Southside that's closer to a gimlet, slightly more tart and floral.
- Only have a rich simple syrup (2:1)? Use about 0.75 ounces and add a teaspoon of water to make up the volume.
Serving, storing, batching
Serve the Southside well-chilled with nothing on the side. It's a cocktail that stands alone. If you're pairing it with food, think light: a summer salad with goat cheese, grilled shrimp, or a plate of oysters. The mint and citrus will cut through the richness without overpowering the seafood.
The Southside is a made-to-order drink; it doesn't keep. The mint will bruise and turn bitter, and the lemon juice will oxidize. If you need to prep ahead, make the simple syrup and juice the lemons separately. They'll both keep in the fridge for up to a week.
For a party, scale the recipe by the number of guests and mix everything except the mint in a large pitcher. When you're ready to serve, add the mint and shake each portion individually with ice. Pre-batching the full drink with mint will ruin it within an hour. For a large batch, consider making a punch-style Southside: combine all ingredients in a punch bowl with a large block of ice and stir until chilled.
Questions people ask

A sidecar is a different cocktail. It's made with cognac, orange liqueur (like Cointreau or Triple Sec), and fresh lemon juice, shaken and served up with a sugar rim. The Southside uses gin and mint instead.
Muddle mint leaves with simple syrup and bitters in a shaker. Add gin and lemon juice. Fill with ice, shake hard for 10-12 seconds, and double strain into a chilled coupe. Garnish with a slapped mint sprig.
The core ingredients are gin, fresh lemon juice, simple syrup, and mint leaves. A dash of bitters is optional but recommended. It's essentially a gin sour with mint.
The simplest is probably the Gin and Tonic or a Rum and Coke—two ingredients plus a garnish. For a classic cocktail with a bit more character, the Southside is still very simple, with just five ingredients and no special technique beyond shaking.
Last word
The Southside is proof that a classic doesn't need to be complicated. It's bright, herbal, and balanced—a drink that shows off good gin and rewards a light hand with the muddler. Master this one, and you'll have a go-to for every warm evening from now on.
