Boosted by an earlier-than-expected seasonal transition and the return of the on-premise channel, sales of Leinenkugel's Summer Shandy have increased 13% year-to-date, according to the Molson Coors Beverage Company blog. "As we continued to excel with distribution and sales and the off-premise, we were able to quickly transition into Leinenkugel's Summer Shandy," Dick Leinenkugel, president and chief beer merchant of Jacob Leinenkugel Brewing Company, told Brewbound.
