Pickle juice is now available in a can, and I'm certainly not mad about it. Gordy's "Fine Brine" for cocktails is a described as a "perfect balance of salty, tangy, and sweet" brine, best served cold.
If you've never had a "Pickleback", you're doing yourself an injustice. Take a shot of Jameson and chase that with a shot of cold pickle juice and it will set you free.
Thought, I believe the mission of Gordy's is to elevate cocktails like a pickle martini or pouring some into a Bloody Mary. Either way, it looks like they are out of stock for now, so keep an eye on their official site.
