A Millie's all-time fan favorite, Concord Grape sorbet is back and better than ever: juicy-sweet Concord grapes are pureed and spun into a jewel-colored sorbet that tastes like the last gasp of summer. Our recommendations? Pair it with one of our peanut butter scoops (we have a few!) for some lunchbox nostalgia, or with seltzer for the most refreshing float you've ever had.
