Yaegaki "Mu" Junmai daiginjou 八重垣 "無" was all gone but, for ankimo, we need sake. We did have several bottles of the US brewed sake called "Haiku" 俳句 (we keep it for emergencies), which is brewed from Californian rice and Sierra water in California by Ozeki 大関酒造. It is not too bad (in an emergency), and is a type of "Tokubetsu junmai" 特別純米酒 but it is a bit yeasty for our taste and we liked to have a better sake with ankimo. Then, we found the last bottle of "Nanawarai" daiginjou 七笑大吟醸 from Kiso 木曽 in our refrigerator, which we hand carried home last year from Japan.
This was good; a very gentle sake without assertive flavors. It reminded us of Dassai 23 獺祭 23. For a more clean fruity taste, we favor our house sake but this sake tasted better than I remembered it. I am not sure if I can get this sake here in the U.S. anyway. In any case, ankimo and cold sake went so well together.
