ASUNCION - UNESCO recognized Japan's ancient process of sake brewing as an "intangible cultural heritage" on Wednesday, which producers hope will boost global interest in the traditional rice wine that dates back centuries but has waned in popularity at home.

Naturally, Japanese representatives at a UNESCO meeting in Paraguay marked the occasion by sampling some sake.

The beverage is made over several weeks by fermenting a mixture of rice, water, yeast and a colorful mold known as koji, in a process more akin to making beer than wine. The end results can be served hot, cold or at room temperature.

While sake plays a significant role in Japanese society and tradition, often served during ceremonies and special meals, demand has ebbed for the drink domestically even as international demand grows.

Sake producers hope UNESCO's recognition accelerates their exports and reinvigorates enthusiasm for the beverage at home.

"We are very happy," said Japan's permanent representative to UNESCO, Takehiro Kano.

"Being recognized internationally by this mechanism will renew the interest of Japanese people in this area, and that could lead to more momentum for transmitting these skills and know-how to the next generation."
