The Casino: A Gin Old Fashioned in a Sour's Clothing

You shake it, and you shake it because of the lemon. A quarter ounce of citrus is barely a seasoning, but it's enough acid and enough aeration to ask for a hard shake over fresh ice. Build it cold: two ounces of a juniper-forward gin, a quarter ounce of Maraschino, a quarter ounce of fresh lemon, two dashes of orange bitters. The Maraschino is the trap. It is sweeter and louder than its low proof suggests, all almond pit and funeral flowers, and a heavy hand turns the drink into syrup. Measure it. Shake until the tin frosts and your knuckles complain, then double-strain into a chilled coupe so no ice shards survive to water it down on the way to your mouth. Garnish with a brandied cherry and a lemon twist expressed oil-side down over the surface. The peel does real work here, lifting the whole glass with bright citrus before the gin even lands.

Here's the thing nobody tells you. The Casino has lemon in it, so every instinct says sour, and every instinct is wrong. A sour is built on a real spine of citrus and sugar in balance, enough acid to define the drink. The Casino has a quarter ounce of lemon doing the job an orange peel does in an Old Fashioned, which is to say it's seasoning, not structure. Strip it back and what you've got is spirit, a sweetener that doubles as a flavoring agent, and bitters. That's the Old Fashioned template, full stop. Gin stands in for whiskey, Maraschino stands in for sugar, orange bitters stand in for aromatic. The drink belongs in the same room as the Benton's Old Fashioned, the Black Manhattan, and the Bitter Giuseppe because all of them are spirit foregrounded and lightly adjusted, with no mixer, no wine, no cream, and no proper sour balance to hide behind. The lemon and the shake are camouflage. The bones are pure Old Fashioned, and once you see it you can't unsee it.

The Casino dates to the early twentieth century and shows up in Hugo Ensslin's 1916 bartending guide, back when Old Tom gin and stiffer Maraschino pours were the norm. Earlier versions leaned sweeter and gentler, the kind of thing served at resort bars to people who wanted to feel sophisticated without tasting too much gin. Time and the dry-gin era sharpened it. It's a cousin to the Aviation, that other gin-and-Maraschino number, minus the violet liqueur and the Instagram lighting, and frankly the Casino is the more honest drink of the two. There's no parlor trick here, no color, no story about a flight to nowhere. Just gin given room to talk, with cherry and citrus murmuring agreement in the background. The Casino survived because bartenders who actually drink kept it alive, the same way a good cook keeps a plain omelet on the menu. It rewards restraint and punishes the heavy pour, which makes it a useful test of whoever is standing behind the stick. If they get the Maraschino right, they can be trusted with the rest of the list.
