I bought a sort of sugary grape syrup in Hong Kong that, mixed with water, makes a refreshing summer beverage. It was ubiquitous at supermarkets there, but if I remember correctly, most of the writing on the label was in English. It could be a British thing.
Does anyone know what this stuff is called, and where it might be available around LA? I've checked Ranch 99's and other Chinese SGV markets, but haven't seen it.
