Ben & Jerry's and the Bonnaroo Music & Arts Festival have collaborated to launch a new Ben & Jerry's ice cream flavor called Bonnaroo Buzz. Bonnaroo Buzz was introduced at an invite-only event to Bonnaroo fans, Ben & Jerry's Chunkmailers and Ozomatli mashers. The new flavor contains light coffee and malt ice creams with whiskey caramel swirls and English toffee pieces. You can find out more about the flavor here and here.
