Carl Loewen is a highly-regarded family winery that started in 1803. Farming is practicing organic. Alte Reben = old vines; in this case 50-70 year-old vines in the Leiwener Maximin Klosterlay vineyard's slate soils. This is terrific dry riesling from a top Mosel producer and a top vintage with several years of bottle age. 11.5% alcohol.
