Florida Georgia Line Celebrates with 288 Bottles of Whiskey On the Wall

The guys from Florida Georgia Line are throwing the ultimate tailgate party Thursday, complete with tons of free booze.

It's all to kick off the launch of FGL's new Old Camp Peach Pecan Whiskey. We're told the folks at Old Camp are rolling in 24 cases for a VIP pregame at the group's New Jersey concert.

Sorry fans, it's not open to the public -- they don't have THAT much liquor ... the tailgate is strictly for Brian and Tyler's close friends and entourage.

Brian tells us ... "It's a ritual we've had since our first shows, toasting and celebrating with our camp before taking the stage."

Fireball whiskey, you're on notice -- FGL's pregame is gonna be a peach.
