Blackberry Juice from Ecuador

I tried this blackberry juice for the first time at my hotel in Guayaquil, Ecuador. In Spanish it's called Jugo de Mora. It's maroon or magenta in color, and sweet, not bitter or sour at all. I'm not sure that it had such a strong blackberry flavor though. It tasted a bit like it had pineapple juice in it as well. It also had slight flavors of strawberry and raspberry. Blackberry juice is very refreshing and went well with my breakfast.
