Looking to explore the world of cocktail bitters? These brands, which range in price from $2 to $8 a bottle, are available at LeNell’s (416 Van Brunt St., between Coffey and Van Dyke streets, Brooklyn, 718-360-0838), and elsewhere as noted.

ANGOSTURA AROMATIC BITTERS (also available at many supermarkets): Classic bitters brand, and deservedly so, with a complex mix of spice notes. “It’s very good for Manhattans or Old Fashioneds,” cocktail historian David Wondrich said. “And it’s excellent with rum, like in a Mojito – not traditional, necessarily, but it works.”

PEYCHAUD’S AROMATIC COCKTAIL BITTERS (also availble from buffalotrace.com): The classic New Orleans bitters, a crucial ingredient to a Sazerac, and the only brand aside from Angostura to survive from pre-Prohibition days. “It’s very distinct from Angostura,” Mr. Wondrich said. “More anise, black cherry, things like that. It blends very well with brandy, or any cocktail using cognac.”

FEE’S OLD FASHION AROMATIC BITTERS: “More of a Christmas spice flavor than Angostura, a little less complex,” Mr. Wondrich said. “But it’s great with old-fashioned whiskey cocktails.”

FEE’S WEST INDIAN ORANGE BITTERS: A classic orange bitters. Fruity and not too spicy, it’s ideal for a martini.

REGANS’ ORANGE BITTERS NO. 6 (also available at buffalotrace.com): Developed last year by cocktail maven Gary Regan, this orange elixir is less orange-y, more complex, and spicier than Fee’s orange product, with lots of cinnamon and clove notes.

STIRRINGS BLOOD ORANGE BITTERS (also available at stirrings.com): Unlike all the other bitters on this list, this new product has no alcohol, and is therefore more like a juice, or even a punch, than a classic bitters concoction. Very interesting flavor profile, though – lots of potential here.

FEE’S PEACH BITTERS: Pleasantly fruity and extremely aromatic, this product was developed by Fee’s about 15 years ago at the urging of Ted “Dr. Cocktail” Haigh, a mixology enthusiast who’s been on a long crusade to revive bitters culture. “I haven’t found much use for it,” Mr. Wondrich said, “but there are some nice Art Deco drinks that call for it.”

FEE’S MINT BITTERS: Disturbingly similar to Scope – use real mint in your cocktails instead.

UNDERBERG BITTERS: Packaged in a tiny, beautiful 20ml bottle (about two-thirds of an ounce), the full contents are meant to be poured into a bitters glass and consumed in one gulp, as a digestif. But according to the LeNell’s proprietress, LeNell Smothers, it also can be used in cocktails. “It’s such a nice little size, you can slip it into your purse, take it with you to dinner, and take a nip of bitters,” she said.
