Okamura Honke is a small artisanal brewery founded in 1854 in the castle town of Hikone. It is the brewery with the most radical but simple way of categorising its products. All sake are merely named by a colour and a number ranging from 40 up to 90. The former is nothing more than the colour of the bottle, the latter corresponds to the polishing rate. Thus the official name of this sake is ‘White 80’, although there are often two versions of each sake, the one pasteurised and diluted, the other unpasteurised and undiluted.
