This time of year, there is certainly no shortage of holiday cocktails, from eggnog to glögg and Hot Toddies to Tom & Jerrys. But there’s also a canon of tried-and-true, year-round classics that can easily shape-shift into holiday pinch hitters. Here, a few tips and recipes for adjusting the flavors of classic cocktails into cozier, festive drinks.

Manhattan

While the Manhattan in its pure form is already holiday-ready, some subtle tweaks can lend it an extra holiday appeal. This can be as simple as selecting certain vermouths: For spice and vanilla, go with Carpano Antica Formula; for a cooling herbal note, Tempus Fugit’s Alessio Vermouth di Torino; for a rich, bitter bite, Punt e Mes. You can also exchange the vermouth for another modifier altogether, like Amaro Averna, to make the Black Manhattan, or coffee liqueur, for a Revolver. Or split the vermouth portion with herbal yellow Chartreuse to stir up a Greenpoint.

Daiquiri

No other drink, aside from perhaps the Piña Colada or the Mai Tai, is more synonymous with summer than the Daiquiri. A simple combination of lime, rum and sugar, it is stripped-down, poolside perfection. But the Daiquiri need not be shunted to the warm months. In fact, the simplicity of its formula and the availability of excellent citrus in winter make it the perfect template for holiday entertaining. One way to easily usher it into the winter is to up the richness with sherry; turn to raisiny Pedro Ximénez sherry to make Chantal Tseng’s PX Daiquiri, or nutty oloroso sherry for Matt Piacentini’s Sherry Daiquiri. Or, turn the Cuban classic into a pre-dinner drink with a dose of Campari or a dash of absinthe or pastis, as in the Greta Garbo.

Margarita

“More an idea than a cocktail,” as Alonso Ruvalcaba writes, the shape-shifting Margarita can easily transform for the colder weather. Ruby red juice and rosemary-infused Cointreau meet in the Blood Orange Margarita, while herbaceous génépy puts an alpine twist on the classic in the El Pepe. One of the most notorious riffs on the Margarita, dubbed the Jägerita, calls on Jägermeister for a surprising take that, with its clove and ginger notes, fits well into the season.

Negroni

An easy party-starter, the Negroni has the ability to transform itself by swapping in a gin that’s heavy on the botanicals; the West Coast is where to look. But for something more brooding, do as Brian Evans does in the Winterized Negroni and add a half-teaspoon of Islay Scotch, or make it smoky with a mezcal base, like Sarah Morrissey’s Negroni Absinthe, which pairs the spirit with crème de cacao. The fairer Negroni can put on a winter coat, too; simply introduce génépy, crème de menthe and Cocchi Americano to the mix, as in Naren Young’s Alpine Negroni.

Whiskey Sour

The Whiskey Sour has spawned an array of riffs to choose from year-round. To make the drink a little more celebratory, add a float of red wine to make a New York Sour. For more richness, swap out simple syrup for maple syrup and add a hit of Angostura bitters, as Erik Adkins does in his Filibuster. Andrew King, in Charleston, South Carolina, takes the bitters to the next level, adding a hefty 12 dashes of Peychaud’s to the Thirsty Monk, which gets an alpine twist by way of herbal génépy and Bénédictine. Finally, with Meaghan Dorman’s Whiskey Business, echo the spiciness of rye with smoky-spicy Ancho Reyes chile liqueur. The result is comforting and familiar while also bringing something new to the table.

Gin & Tonic

The refreshing, breezy Gin & Tonic template is one you’re much more likely to encounter in the warmer months, but the bubbly drink can transcend seasons with just a few tweaks. Mexico City’s take on the G&T, the Salmoncito, spotlights winter citrus, for instance, while in Marshall Minaya’s Tart Gin & Tonic, an herbal shiso garnish and bracing Suze dress it up for any occasion. For something extra celebratory, turn to France’s answer to the G&T: Calvados & Tonic, built on a base of the French brandy.

Martini

As with many stirred classics, the Martini isn’t bound to one particular season. But that doesn’t mean you can’t turn the template decidedly more winter-ready. For added richness, look to sherry once again, like in the Tuxedo, or chocolatey mole bitters, as in Jack Schramm’s Silent Night, which can easily be prepared ahead of time. In fact, pre-batching and -freezing may be the best hack for preparing to host a holiday party. And if you’re going to make a freezer Martini, you might as well make it the very best one.
