“Pickleback” is a drink of whiskey and pickle brine. The drink was invented by Reggie Cunningham in 2006 at the Bushwick Country Club in Williamsburg, Brooklyn. Cunningham used Old Crow whiskey and McClure’s pickles.
   
 
Wikipedia: Pickleback
A pickleback is a type of shot wherein a shot of whiskey is chased by a shot of pickle brine. The pickle brine works to neutralize both the taste of the whiskey and the burn of the alcohol. The Pickleback is sometimes also called a Piskey.
 
History
While the origins of a pickle brine chaser are unknown, the term “Pickleback” was introduced to the patrons of The Bushwick Country Club bar in Williamsburg, Brooklyn by Reggie Cunningham in 2006. Also the name of a Facebook petition to see if a Pickle could gain more fans than Nickelback.

International Reach
The “pickleback” has since spread from Brooklyn to Europe, with many elite bars now offering picklebacks on their menu.

Called The Supersize, you get a PBR tall boy and a shot of rotgut whiskey for $6. My advice is to ask for the “pickle back” which is a shot of pickle juice to chase the whiskey. I know.

Littrell, meanwhile, has an interesting (though merely conjectural) theory about the drink’s possible origins. As the manager for a touring band, he spent a lot of time crisscrossing Texas. He says long-haul truckers there are known, when they stop for a drink, to take a shot of pickle juice to keep the alcohol’s diuretic effect tamped down. “Central Texas, it’s pickle culture: they drink the juice and that salt retains liquid. It’s an old Texas driver thing.”
 
Others point out a possible connection to the Russian custom of consuming pickles with vodka, or a similar ritual with tequila in parts of Mexico. Reggie Cunningham, who’s now widely credited with the drink’s invention at the Bushwick Country Club, was quick to set the record straight, while possibly supporting Littrell’s theory. “We were storing pickles for the McClure’s guys in the basement when they first started their Brooklyn operations,” he said. “I was just munching on some one night when this gravelly-voiced Southern chick asked for a shot of the juice alongside her whiskey. I said, ‘No way,’ but she made me have one with her, and I think I had, like, a dozen that night. Totally cured a cold I had, and no hangover. It took off like hell from there. That one drink totally cemented the bar.”

11 THINGS YOU DIDN’T KNOW ABOUT PICKLEBACKS

1. People have been chasing whiskey with pickle brine for God knows how long, but the term “pickleback” wasn’t coined until 2006. As wordsmith/ Brooklyn bartender Reggie Cunningham tells it, in the year of our Lord 2006, he was approached at the Bushwick Country Club by a gold-toothed woman who, in a “filthy redneck voice”, made the barman do a series of whiskey shots followed by brine. He fell in love and dubbed it the pickleback.
 
2. Aliases for the pickleback include “Piskey Whickle” and “Bartender’s Handshake”.
(...)
5. Old Crow was the first whiskey served with a newly named pickleback. Currently, Jameson is outpacing Old Crow as the whiskey of choice for a pickleback.
(...)
8. The original pickleback used McClure’s pickles, which are manufactured in Brooklyn and Detroit (you may remember it from such pickles as “Spicy” and “Garlic Dill”). It is generally frowned upon to use mass-produced pickles for a pickleback.
