ムッシュ
Purchased as a souvenir from Kusatsu. It seems to be a limited edition product only available here.
It is sharp and dry. Slightly acidic. It has a moderate umami flavor, which is not bad, but Yumomi Musume, which I bought together with it, was better. The label is written in English, so I thought it might be a product for foreign tourists.
