Before the war and after the war, varieties mainly made in Kagoshima. It seems that it used to be used for shochu before, but now I can hardly see it.

It can not be harvested about 60% compared with Kogane-sengan, it is watery, it seems to be difficult to process. While many sweet potato ingredients have white skin, chicken sweet potatoes are red skin and characterized by hardness.

We have more and more sweet potato in Japan. But please compare main potato ‘’Kogane-sengan’’ to red or purple potatos. So that you can easy to understand of sweetness from each potatos.

Shimon-imo , Genchi-imo is rare potato for using Shochu .

I understand you want to try all , but first, try Kogane-sengan and red , purple potato.

Vibes Point

Why Shochu maker use so many kinds of potato? Of course they decide the ‘price’ , but some of reason why some of maker don’t use without kogane-sengan.

Red and purple potato are really sweet so when we make Shochu , the tank and cray pot will be so sticky , it is so beautiful color but hard to clean all.

When distilling , inside of Distiller become sticky as well . and more , the aroma is different from kogane-sengan, so maker afraid the aroma will transfers to distiller.

My favorite potato for Shochu is kogane-sengan cuz of strong taste but sometime when I’m weak but wanna drink shochu , I choose red purple potato because it tend to have smooth taste.
