With most of the leaves now on the ground instead of on the trees, it might seem a little out of place to be talking about summer, but Newton, Mass.-based Restaurant Sciences LLC is keeping the summer season on our brains.

Last month, the independent firm identified the Top 10 adult beverage concoctions of the summer. After analyzing 50 million cocktail spirits purchases at bars, restaurants, nightclubs, sports venues, and recreation/leisure facilities from June through August, Restaurant Sciences found that Margaritas topped the list with 20.5 percent of the market share for the foodservice industry.
