| Cold winters in Niigata allow long fermentation that leads to a clean, pure sake |
The Japanese aesthetic is responsible, and I mean this mostly about food, but not exclusively. Expensive works of Japanese art traditionally are breathtakingly simple. Think about the Zen rock gardens of Kyoto: how we're supposed to feel from looking at three rocks in a field of sand.
Japanese food is the same way. If you really want to drop serious coin on sushi in Tokyo, you don't get 49er rolls -- you get a single piece of pristine fish on a log of vinegared rice. You are to appreciate the cut, the delicacy. The taste should be clean, not complex: simple.
Naturally, the right sake for that kind of food is also clean, simple, pristine. But it's anathema to the wine and spirits world. Expensive spirits generally taste of longer time in oak. And from a sake point of view, I can divide the world's wineries by their goals: power, or complexity.
I can't think of a high-end winery that pursues the goal some Japanese breweries are after, particularly in Niigata.
