AMP Energy and racing superstar Dale Earnhardt Jr. are debuting a new sour grape flavor—Dale Jr. Sour—available for a limited time at participating 7-Eleven stores. The NASCAR circuit driver selected the sour grape flavor, and the can features a likeness of him and his No. 88 Chevrolet SS. Sampling events occurred at a handful of Charlotte, N.C., 7-Eleven locations during the launch.
