I think the flavor I tried that first day was boysenberry, but plum is now my new favorite. Every trip to the Asian supermarket (Fubonn, here in Portland) has me searching for the best brands. They tend to be popular, and sell our very quickly.
Just mix 1-2 oz. with some club soda, and you've got a fabulous non-alcoholic cocktail that doesn't taste like it'll rot your teeth or make you crave the hard stuff.
After photographing these bottles, I noticed the little slogans for each flavor:
"Plum aroma, sweet and sour taste that moisture your throat and quench your thirst."
"Lemon keep youth, beauty and maintain healthy."
"Scent of strawberry is just like the scent of happiness and sweet love."
Each label ends with:
"Sweet and sour, refreshing taste, it gives you a new experience in love."
