Meaning of words
Gen = whole, shu = alcohol
whole in alcohol, this means that the sake is unreduced, the producer has not added water (warimizu) just before bottling to lower the alcohol content and make the sake more tender.

The sakes GenshuGen = Integral
Shu = alcohol
Genshu = Integral in alcohol
This means that the sake is unreduced, the producer has not added water (warimizu) just before bottling to lower the alcohol content and make the sake more tender. are mainly Namazakes (unpasteurized sakes also called just "  NamaNama is short for Namazakeunpasteurised raw sake, unpasteurised raw sake " but also often sakes called KoshuKo = vieux Shu = alcool Koshu = vieux sake les sakés koshu sont des sakés longuement maturés (old pasteurized sakes) which need a high alcohol content to age well, some koshu in our catalogue are almost 40 years old!

genshu sakes can have an alcohol content of up to 20° or even more in theory, which is a lot for a fermented drink but not much compared to a spirit.

I like to say that a good Genshu Nama ( unpasteurised undilited raw sake) sake should have a great drinkability like a wine and the explosion and length of a spirit without the fire (of the alcohol).
