As a category, cocktail bitters are both venerable and novel, familiar and curious. While there are a select few that have stood the test of time uninterrupted (Angostura and Peychaud's have maintained an unbroken lineage), many bitters being (re)invented today are throwbacks to styles from the era when bitters were thought of as medicine. Consider the case of celery bitters.
Celery bitters have been produced since the 19th century by a range of bitters-makers, but they never achieved the prominence of, say, aromatic or orange bitters. There aren't a ton of classic cocktail recipes that call for celery bitters by name. (There's the Celery Sour, made with equal parts celery bitters, lemon juice, and pineapple syrup circa 1917, but there's no sign this drink ever really caught the public's imagination.)
However, the recent bitters renaissance has seen a proliferation of celery bitters, and in short order, bartenders have created a variety of cocktails calling for the stuff. Perhaps it's the rise of picklebacks and savory cocktails that's responsible for the return of celery bitters, or just the inherent curiosity of the modern cocktail movement, but it seems that celery bitters aren't going away any time soon.
Celery bitters have such a distinctive flavor that they're a little difficult to deploy correctly, let alone frequently. But when they work, they can be utterly transcendent.
Celery bitters lend an enticingly vegetal and citrusy edge that plays well with traditional savory drinks (Bloody Mary, anyone?) but is also lovely with the floral notes of gin (just one dash in a martini is a revelation, and 2 to 3 dashes takes the sweet edge off a G&T), as well as the grassy, herbal undertone of tequila. Vermouth and sherry can serve as a bridge. And while celery bitters can be successfully deployed with dark spirits, it often helps to bring in other bitters, as well, to achieve a blended effect. In the Fourth Regiment, for example, Angostura and orange bitters join the celery for a complex riff on a Manhattan.
I think part of the reason that bartenders have been in love with celery bitters recently is the novelty they bring to the table: nothing could be further from the old sour-mix-and-cranberry-juice drinks that darkened bars in previous decades. But maybe bartenders (and folks making drinks at home) are just excited about the challenge factor of finding that new combination to make the celery sing. Bottom line: if you're into savory flavors and willing to experiment a bit, celery bitters can put a completely new twist on a variety of drinks you thought could never surprise you. And if you're not quite so adventurous, there's absolutely nothing wrong with buying them just to make a truly excellent Bloody Mary.
So which celery bitters should you buy? Here are my favorites.
Bitter Truth Celery Bitters
Scrappy's Celery Bitters
These are also my favorite for mixing up a tall glass of home-made Cel-Ray soda.
