I've tried just "28 Black Açaí" and am disappointed it totally. While the refreshing effect can be felt and tasted the drink is of higher quality than many a competitor, but the name Açaí is a joke. The flavor missed the intense note of acai berry perfect. Anyone who has tried in Brazil before the famous Açaí Sorbet will attest to that. Taste the drink looks more like a cough syrup for children.
