Soft-feeling on the tongue, Oka’s transparency of flavour matches the clarity of the colourless liquor. It is floral rather than fruity, though there is a touch of pear, and perhaps melon.

Dewazakura is one of the most innovative sake-makers in Japan, using new yeast strains, rice varieties and brewing techniques to craft distinctly original sakes. The brewery’s "Oka" label, introduced in 1980, is credited with popularising ginjo sakes at a time when few people in Japan had heard of them. In the early ‘90s Dewazakura began storing unpasteurised sake at -4 °C to keep it as aromatic and flavourful as possible until bottling. New labels made from Dewasansan and Omachi rice have added to the brewery’s reputation as a creator of modern sakes that are fragrant, delicate and refreshing.
