情け嶋 is my favorite Shochu, a type of Japanese spirits, and I have knows it is a Mugi-Shochu (made from barley). However, I recently discovered an Imo-Shochu (made from sweet potato) version at Takimoto liquor shop in Kyoto, and I feel its taste is ideal for me. Good flavor of barley and the heavy taste of sweet potato. All for only JPY 1,200. Bon Appétit!
Bought at Takimoto (one of the very best liquor shop for me)
