What do Arnold Schwarzenegger and Sesame Street have in common? Meet Ernst "Erni" Loosen, the global powerhouse of German wine who took over his family estate in 1988 and transformed Mosel Riesling into a household name. Alongside his long-time cellar master, Bernhard "Berni" Schug, this dynamic duo has spent decades crafting wine's ultimate gateway drug. From high-octane, muscular single-vineyard masterpieces born on 130-year-old ungrafted slate slopes to incredibly accessible bottles enjoyed from Houston to Bangkok, step inside the iconic world of Dr. Loosen to see why these high-acid, energetic wines promise, "I'll be back."

According to 14th-century German lore, a dying Archbishop was completely cured after drinking a cup of wine grown on the steep, sun-drenched slopes of Bernkastel. That legendary 3.25-hectare parcel became known as the Berncasteler Doctor—and its wines were once so prized they rivaled Bordeaux and sold in apothecaries as medicinal tonics. Step into the history of Weingut Wwe. Dr. H. Thanisch (Erben Thanisch), an estate defined by nearly 400 years of family heritage and an extraordinary five generations of female leadership, to discover how they craft elegant, ageworthy Rieslings on borderline terrifying 65-degree slate slopes.
