Shochu refers to the Japanese low-class distilled spirits, made from rice, corn or wheat. It is distilled as compared to Sake which is brewed. Moreover, as compared to Sake (12 - 15\% alcohol volume), Shochu is much stronger, usually about 35 or 40\% alcohol volume. It is the cheapest drink in Japan as measured by its alcohol content, only about the same as price or cost of Sake
