The Rhine River valley has vineyards on both sides along much of its length. In four countries, (five, if you include a mere 30 acres in the Vorarlberg region of Austria), vineyards cover select slopes of various geologies and topographies. Five sections of the Rhine have vines: The Alpine, the High, the Upper, the Middle and the Lower. The Alpine Rhine, from Reichenau to Lake Constance, mostly flows through a mostly wide valley lined by Alps on either side. The Graubunden Canton north of Chur, the tiny country of Liechtenstein, and the Sankt Gallen Canton, all have vineyards on the slopes facing onto this section of the Rhine. Since I had already visited some of those vineyards on a hike in the Graubunden Canton, (see here) I decided to visit the Sankt Gallen Canton to see some of their vineyards, and to learn about some of their wines.
