Question 1

What is Koshu FOS?

Accepted Answer

F.O.S. — 'Fermented On Skins' — was first made in 2004 to highlight the distinctive character of Koshu through skin fermentation. 
Inspired by wines encountered in Friuli, Jura, and Georgia, Coco Farm has continued to evolve F.O.S. through experimentation each vintage. The similarity between Koshu and Georgia's Rkatsiteli eventually led them to ferment the wine in custom-made Mashiko-yaki clay vessels from Tochigi. 
Bright amber in the glass, with persimmon, yellow peach and mandarin over black tea, clove and toast, with gently acidity, soft umami and a long, savory finish.
