Grapefruit bitters add brightness to your cocktails
When I started behind the bar, some 20-plus years ago, there was always one constant, no matter where I worked — one dusty little bottle of Angostura bitters.
Nobody ever used it. Few probably knew why they even had it. Bar owners must have bought it as a talisman or in accordance with some long-standing bar tradition. But then, somewhere in the early years of the new millennium, a few curious souls dusted off the bottle and decided to see if a Manhattan could be improved by following its original recipe and adding a dash of bitters.
It was nothing less than a transformation and, it turned out, wasn’t even the only application. Bitters add a much-needed dimension of flavour to a range of cocktails, from sturdy, spirit-forward numbers that need a little perking up to sweet tiki drinks, in which sugar spikes are corrected by a dash of bitters.
Angostura is hardly the only brand anymore, either, with hundreds of new craft bitters companies producing esoteric flavours such as jerk spice, chocolate mole and cranberry bog. Seriously. Sometimes it seems as if a crazy new label is being launched daily. Rather than trying to keep up (an impossible task), most bartenders buy the old standards and pick a few aromatic concoctions that really speak to them.
In Toronto, few brands can boast the loyalty that Coster’s Prescription Bitters have garnered. It’s a boutique bitters brand with a clutch of devotees who love the signature flavours: Burnt Citrus, Coffee and Smoke and Blackstrap Ginger. Mark Coster, founder, started making bitters to learn more about the taste elements he was adding to his cocktails.
“When you make your own, you think of flavours in a much more visceral sense than when you’re just buying off the shelf,” he explains. “It’s good to understand the process.”
Coster warns, though, that it took time and a fair bit of trial and error to figure out how to balance some of the more complicated flavour profiles he works with. His extremely popular Burnt Citrus bitters was a happy accident. He forgot to take his citrus peels out of the oven and discovered he liked the flavour better anyway.
Coster is kindly saving our readers a little trouble by passing on his tried-and-true formula for grapefruit bitters, perfect for adding a touch of brightness to both gin and tequila cocktails.
