ST. LOUIS — Anheuser-Busch is continuing to blur the line between beer and cocktails. The brewer’s latest addition to the popular Ritas family is Bud Light Lime Cran-Brrr-Rita, a limited-edition winter offering. Cran-Brrr-Rita hits store shelves in November, and will be available in 12-packs, 8-oz. cans and 25-oz. cans. Straw-Ber-Rita has been a huge hit this summer and is the largest share gainer in the beer industry this year, according to A-B.
