In the US, Satoh Kuro is simply known as "Satoh" as none of the distillery's other product lines reach our shores. In Japan, their national premium labels are Satoh Kuro (black koji sweet potato, Satoh Shiro (white koji sweet potato), and Satoh Mugi (barley). All are delicious, but only Kuro comes Stateside.
The English language has hundreds of words to describe colors. Japanese has just a few. Contrarily, Japanese has hundreds of words to describe taste or aromas while English has relatively few. This reflects a profound cultural difference in which senses dominate the human experience. Westerners tend to concentrate very much on visual stimuli and rely less on aroma and taste in making decisions. On the contrary, Japanese culture is essentially obsessed with the aromas, tastes, and textures of food.
Sometimes it is best to rely on good luck than preparation. On our third night in Fukuoka, after visiting Kitaya Shuzo & Nishi Yoshida during the day, we met up with Seikai's friends from school for dinner at an organ meat izakaya (story on that experience coming soon). Afterward a few of us decided to have one more drink - shochu of course.
