“This cocktail was originally designed for our annual Blueberry Festival in August,” says Heather Ruhle, the beverage manager at Alyeska Resort in Girdwood, Alaska. “The Valley of Girdwood explodes with amazing blueberries every year, so we wanted to celebrate that and incorporate it in a cocktail. The drink comes out a beautiful deep purple. It was so popular we decided to keep it year round at Bore Tide Bar at the top of the mountain.” Plus, blueberries are an antioxidant superfood, so technically it's healthy.
