During a trip to the fruit drink heaven of Florida, Miami, we stepped into Time Out Market and spotted a frozen cocktail with some of our favorite fruits. The combination of tropical fruits with berries, acidic lemon and dehydrated banana just was down our alley. This Tiki Inspired Sour is our take on this cocktail but with ingredients that makes more sense, both in a beer and to our climate. We layer tropical guava over a rustic raspberry base. Our house culture provides some extra acidity to break through the soft addition of banana and fragrant vanilla.
