The supplier for Tanners’ impressive own-label Mosel Riesling Kabinett is none other than the Max Ferd. Richter winery, which is something of a coup. The result is delicious. It’s at the lower end of the sweetness scale (at 27 grams per litre), showing 11% alcohol and a comparatviely “dry” finish. Youthful and zingy, with a touch of carbon dioxide and racy, palate-tingling acidity.
