Casino
The Casino belongs to the Aviation's family tree and arrives with a named author: Jacob A. Didier printed it in his 1909 The Reminder, Old Tom gin with maraschino, orange bitters and lemon, one of the era's great sweet-gin sours. It shares three ingredients with the Aviation and predates the violet fashion entirely: this is the branch without the sky. Old Tom is the load-bearing choice: the lightly sweetened gin style rounds the maraschino's dry cherry funk and lets the spec run without added sugar, the drink balancing on the spirit itself. Orange bitters, the period's house seasoning, bridge the lemon to the liqueur, and the whole reads brighter and drier than its sweet-gin base suggests. It survives as the connoisseur's Aviation, ordered by drinkers who want the maraschino conversation without the crème de violette's cameo, and it gives the Old Tom bottle its best showcase in the sour family.
Glassware: Coupe Glass
Garnish: Lemon Twist and Maraschino Cherry
Ingredients
40ml
The load-bearing spirit: its gentle sweetness balances the whole spec without added sugar. London Dry needs a syrup correction and makes a different drink.
10ml
The Aviation family's signature, in a deliberately supporting measure. Ten millilitres perfumes the drink with dry cherry and almond without ever taking it over, which is what the 1909 balance assumes.
10ml
A short, sharp line by sour standards: the 1909 spec runs aromatic rather than tart.
2 dashes
The period seasoning bridging lemon to liqueur: the same dashes the era put in its Martinis.
Instructions
Add the Old Tom, maraschino, lemon juice and bitters to a shaker with ice.
Shake for 10 to 12 seconds.
Double strain into a chilled coupe.
Express the lemon twist, drop it in, and add the cherry.

Expert Tip
Old Tom is the recipe, not a preference. The spec contains no syrup because the gin brings its own sweetness, so a London Dry leaves the drink sharp and hollow. If dry gin is all you have, add 5ml of simple syrup and accept that you have made something closer to a violette-less Aviation. Ten millilitres of lemon is period-gentle. The 1909 palate wanted these drinks aromatic rather than tart, and modern drinkers often find it soft. Pushing the lemon toward 15ml is a defensible modernisation that breaks nothing; going further starts fighting the Old Tom. Two dashes of orange bitters, not Angostura. Orange bridges the lemon to the maraschino, which is exactly the seam this drink needs closing.
Flavour Profile
The Origin
Jacob A. Didier’s The Reminder of 1909 preserves the Casino with its author attached, a rarity for the era: an Old Tom sour built on maraschino and orange bitters at the height of both ingredients’ fashion. The Aviation appeared within a few years sharing three of its four parts, and the two drinks have been compared ever since.
The Old Tom Question
Old Tom is the gin style that sits between genever and London Dry: botanically similar to dry gin but lightly sweetened, which is how most gin was drunk before the dry style took over late in the nineteenth century.
That sweetness is structural here. The Casino has no syrup in it at all, and the balance depends entirely on the gin supplying what a sour would normally take from sugar. Substituting London Dry does not make a drier Casino, it makes an unbalanced one, sharp at the front with the maraschino left exposed.
Patch it with 5ml of simple syrup and you will get a perfectly good drink, but it will be an Aviation without the violette rather than a Casino, and that distinction is the whole point of the recipe.
Against the Aviation
The two drinks split on one bottle: the Aviation adds crème de violette and dry gin for its sky-coloured reading, the Casino keeps Old Tom and lets the maraschino lead unpainted. Tasting them in sequence is the fastest lesson in what each signature bottle actually contributes.
How to Serve It
Up, cold and aromatic, in the Aviation’s slot for drinkers who prefer their cherry conversation undecorated. The 1909 spec is period-gentle on citrus: sharpen the lemon toward 15ml if your palate lives in this century.
The Maraschino
Ten millilitres is a supporting measure and it is deliberate. Maraschino is distilled from whole marasca cherries including the stones, which gives it a dry, faintly funky almond character rather than the sweet cherry flavour the bottle's appearance suggests.
At this volume it perfumes rather than flavours. The drink smells of cherry and almond and tastes mostly of gin and lemon, which is the effect the 1909 spec is after. Push it to 20ml, as some modern versions do, and it takes over: the almond turns medicinal and the Old Tom disappears underneath it.
Luxardo is the standard bottle and Maraska the usual alternative. Avoid anything labelled cherry liqueur, which is a different product entirely.
The 1909 Palate
The Casino runs 60ml of gin against 10ml of lemon, which by modern sour arithmetic is barely citrus at all. A contemporary sour would use 22.5ml or more.
The Spirit
Old Tom GinA lightly sweetened gin, rounder than London Dry and older than it. The Victorian classics were written for this style, which is why some of them read drier today than their authors can have intended.
Frequently Asked Questions
What is the difference between a Casino and an Aviation?
The Casino keeps Old Tom gin and no violette: maraschino, lemon and orange bitters on a lightly sweetened gin base. The Aviation swaps to dry gin and paints the sky in with crème de violette. Same family, one bottle apart, and quite different in the glass.
Who created the Casino?
Jacob A. Didier, who printed it in his 1909 bar book The Reminder. That makes it one of very few specs from the period to arrive with a named author attached from the start, rather than being credited backwards by later writers.
Can I use London Dry gin?
With a small syrup correction, yes, but the drink changes character. Old Tom's built-in sweetness is the only sugar in the spec, and the balance it provides is the point. What you get with dry gin and syrup is closer to a violette-less Aviation.

Aviation
The Aviation is a gin sour with a sky in the glass. Hugo Ensslin published the original recipe in his 1916 Recipes for Mixed Drinks, the first known printed source: gin, maraschino liqueur, crème de violette, and fresh lemon juice. The crème de violette gives the drink its defining characteristic, a pale lavender colour between blue and grey, the colour of an early morning sky at altitude. For most of the twentieth century crème de violette was virtually impossible to source outside specialist suppliers, and the ingredient disappeared from most published versions. Bartenders made the drink without it for decades, a perfectly good gin sour with maraschino that lacked the colour and floral dimension the original was built around. When Rothman and Winter relaunched their crème de violette for the American market in 2007, the original recipe was restored and the drink found a new generation willing to seek out the correct ingredients. The Aviation with crème de violette is a different drink from the one without it. The violet brings a floral softness no other ingredient replicates, sitting between the maraschino’s cherry complexity and the lemon’s tartness. The colour alone is worth the effort of finding the bottle.

Last Word
The Last Word is one of the great equal-parts cocktails: gin, green Chartreuse, maraschino liqueur, and fresh lime juice in identical measures, shaken and served up. No component leads and no component follows. Each of the four is assertive enough to dominate a lesser recipe, and the fact that none dominates this one is the drink’s central achievement. It originated at the Detroit Athletic Club around 1915, documented by Ted Saucier in his 1951 book Bottoms Up and attributed to vaudeville performer Frank Fogarty, who allegedly introduced it to the club. It disappeared almost entirely during and after Prohibition and was rediscovered in the early 2000s by Seattle bartender Murray Stenson, who found it in Saucier’s book and put it on the menu at the Zig Zag Café. From there it spread through the craft cocktail world and has not left. The revival was deserved. Green Chartreuse brings herbal intensity, maraschino brings cherry sweetness and a faint bitter almond note, fresh lime brings tartness, and gin holds it together. Each sip reveals a different component leading depending on where in the glass you are. It is a drink worth paying attention to.
Gin Sour
The Gin Sour is the sour family’s plainest statement and one of its oldest: spirit, lemon and sugar, the template Jerry Thomas codified in 1862 applied to the botanical spirit, predating most of the famous gin drinks that descend from it. Every White Lady, Bee’s Knees and Clover Club is a Gin Sour that learned a second language. Its plainness is the point. Three ingredients expose the gin completely, which makes this the sour that teaches botanicals: a juniper-led London Dry gives the classic spine, while a citrus or floral gin turns the same spec into a different afternoon entirely. The optional egg white borrows the Boston Sour’s silk without changing the argument. It sits in the canon as the missing link drinkers skip past, ordering its descendants without ever meeting the ancestor. Made with a good gin and honest lemon, it explains in one glass why the template conquered the world.
