Mountain Lion is the Food Lion equivalent to Mountain Dew. It is available in cans and PET bottles. Like all Food Lion diet drinks, Diet Mountain Lion is no longer sweetened with Splenda, and they now use aspartame. Mountain Lion tastes very similar to Mountain Dew and Mello Yello. Diet Mountain Lion is sweeter than Diet Mountain Dew. Mountain Lion contains about the same amount of caffeine as Mountain Dew. Mountain Lion can be found at Sweetbay Markets.
