Fat-washed cocktails utilize a simple technique that makes an impact, so it’s not surprising innovative bartenders employ it and experiment with a wide range of flavors and textures. Fat-washing brings richness, body, and weight to a drink without the need for excessive spirits, liqueurs, artificial flavors, or sugary components. 

Instead, it allows umami to take its rightful place on the bartender’s flavor wheel next to bitter, sweet, sour, and spice. A fat-washed spirit is a spirit transformed, enriched with a fat’s flavors without its calories. Its essence without its overt presence.

The History

Most fat-washed cocktails before, say 2018, there’s a solid chance came bacon-washed and with bourbon. Invented in New York City in 2007 by legendary bartender Don Lee at PDT, the Benton’s Old Fashioned launched the trend. According to mixology lore, Lee took inspiration from the enfleurage method developed by 18th century perfume makers to concoct the now famous cocktail. 

When the fat-washed cocktail trend first began trickling out of NYC and into forward-thinking mixology markets far and wide, bacon grease was the fat of choice. Pioneering mixologists found that infusing its essence into a barrel-aged dark spirit not only soaked in the flavor of bacon, but also improved the texture of the spirit. Bacon-washing bourbon results in a subtle, smokey-salty undertone and rich texture that sings of the breakfast meat without an overbearing thickness or heaviness. Today’s culinary-driven bartenders realized bacon is just the beginning. 

The Process

“You can basically use any fat you want, butter, beef tallow, pork fat, whatever,” said Mason Nack, a bartender at the brand-new Le Forêt, a cocktail-forward French spot in the former Beatrice & Woodsley space on South Broadway. Fat, he added, becomes soluble in alcohol, so when it’s infused into a spirit the aromatics and flavors of the fat come through, but not the unctuousness. 

At its core, the method consists of a simple trick of the trade. Nack advised, “Add the fat to a spirit, mix it together, and let it infuse at room temperature for a bit, then stick it in the freezer.” As it freezes, the fat separates from the liquid, forming a cap on top of the spirit that’s easy to separate from the liquid below. Remove the fat cap and strain the liquid to filter out any solids. What remains is a spirit transformed. 

At Le Forêt, the process employed to make the Duke of Mirepoix, which Nack describes as a blend of fat-washing and milk punch. On the menu, the drink is described as “gin, celery cordial, lime acid, whey, carbonation.” 

What Makes a Spirit Fat-Washed

Just how Champagne is sparkling wine but not all sparkling wine is Champagne, all clarified cocktails technically are fat-washed (with whole milk for the most part), but not all fat-washed cocktails are clarified. 

Nack explained:  “When you mix whole milk into a cocktail with any kind of citrus in it, the citrus causes the milk fat to curdle, and those curds act as a filter that pulls out heavy particles and colors.” In the end only the whey remains.  

The whey contains water, milk sugars, proteins, and minerals, and it can act as a carrier for the cocktail’s flavors. This helps distribute the nuances evenly throughout the drink. The proteins and sugars in whey binds with other flavor compounds, potentially altering the drink’s taste profile in subtle, complex ways. 

Also, says Nack, “What the process does is take away most, if not all, of the color from a cocktail. It makes it completely transparent but maintains all of the flavor while enhancing its mouthfeel—makes it a little richer while still having that acidic punch to it. So if you were to do, say, a margarita, it;s still gonna taste just like a margarita, but it’s going to be a lot silkier, a lot smoother.” 

On the other hand fat-washing is a technique where a spirit becomes infused with a fat in order to add depth and flavor. “It kind of does the same thing as the milk wash without the clarifying part of it,” says Nack. “It infuses the flavor and improves the texture of the spirit. This makes it a little richer, a little smoother while infusing all that flavor, too.” 

Meat-Forward Cocktails

Why stop at bacon? In Denver, creative bartenders forge fatty new paths of culinary-driven cocktails that push the boundaries of mixology. At Honey Elixir Bar, a pancetta fat-washed rum comprises allspice dram, pineapple, cherry, brown sugar, and saline to make the Freyr’s Brew. At Welton Room, duck fat-washed whiskey meets maple syrup and rhubarb bitters for a savory old fashioned. Williams & Graham’s Flabbergasted uses chicken fat-infused Balvenie DoubleWood 12. Moving on to Retrograde, that hidden bar inside Sweet Action Ice Cream in Uptown, the Voyage Into Space features a base of chorizo-washed mezcal. 

Choose Your Fat (Vegan Too)

While rich animal fats complement the flavor profiles of barrel-aged whiskeys, it doesn’t always work well in lighter spirits. When washed with a gin or a vodka, animal fat tends to dominate the resulting flavor. Plant-based fats on the other hand prove easier to work with. They tend to be more shelf-stable so the prep is less extensive and the result less likely to spoil. Enter a whole line of vegan-friendly fat-washed cocktails. 

A full range of oils can be used to fat-wash spirits, including those sourced from olives, sesame, peanut, coconut, and avocado, among others. At The Family Jones Spirit House, a sesame-washed gin offers a nuanced foundation to the Cold Lovers Waltz. The cocktail’s botanical sharpness is mellowed out by the nutty, toasted depth of sesame. 

At Room for Milly, My Dearest Pike becomes anchored by the grassy, earthy tones of coconut-washed Rhum Agricole. Head to Deviation Distilling, for an entire menu dedicated to fat-washed cocktails featuring the distiller’s own spirits. For example, hazelnut-washed Citrus Rosé gin in the Hasel & Spice. There’s also a feta olive oil-washed gin, in the Deviate From the Norm. The Mango Lassi, the pistachio-washed blood orange gin creates nutty and bright citrusy nuances. 

Taste for yourself what a big difference it can make at the aforementioned spots and other venues around town.
