It was a Thai invention originally, and these days you can still find it anywhere.
Good chances are there is a can in the mini-bar of your hotel. The name "Krating Daeng" is on the T-shirts with the Red Bull logo, but they pronounce it in another way, and it is written in Thai, in fact, it is the only Thai I can read...:-)
They have many different names now, just ask for "Lippo" when you're in a bar.
