In Marcus' absence this week, we're throwing back to an earlier chat with Japanese Master Bartender Hidetsugu Ueno. Owner of the world renowned Bar High Five in Tokyo, Ueno is the most revered of anyone behind a bar in Japan, which is astounding when you consider the fact he doesn't even drink.

We asked about the gruelling master & apprentice style of bar tutelage that's ever present in Japan, his meticulous ice-carving and dilution techniques, and the subtleties of making conversation with customers. He's as fascinating as ever.
