Surprisingly easy to drink. It rides on the tongue without any sticking. But when it goes down your throat, you can feel the alcohol. You want to enjoy it in your mouth. It tastes better when it hits the chin than on the tongue(?).
I'm not sure about the sour cream taste, but it's definitely refreshing.
The sweetness comes first, followed by a spiciness that is typical of alcohol, but the aftertaste is sluggish. After drinking, the nose smells like mangoes.
