Adele and I remember vividly the summer of 1990 in Europe. We traveled through much of France in extremely intense heat. The temperature in the Loire Valley was in the upper 90s and reached 104 when we arrived in Bordeaux. A few days later, when we stayed in a hotel in Carcassone without air conditioning, some guests slept with their doors open. If the heat debilitated people and made sightseeing onerous, it was certainly beneficial for the grapes. 1990 was the sort of vintage that occurs only once every 20 or 25 years, in which outstanding wines are produced in nearly every European wine region. It was probably the best vintage of the 1990s for Red Bordeaux, a milestone in modern Red Burgundy, superb in Tuscany and the Piedmont, excellent in Rioja. Yet, perhaps no wine region had more exceptional results than the Mosel region of Germany. In 1990 its Rieslings had a purity of concentrated fruit combined with high but refreshing acidity that is more commonly associated with years of less extreme heat and sunshine. The balance of these qualities is what distinguishes most 1990 Mosels from those of other fine years. Excluding 1971, which for many lovers of German wines remains the standard by which great vintages and wines are measured, I consider 1990 my favorite Mosel vintage of the last half century (Verdicts are still out on 2001 and 2005). I was reminded just how wonderful these wines are last night. After dinner Adele and I shared a 1990 Erdener Teppchen Auslese from Meulenhof, whose wines have been imported to the US for many years by Terry Theise. Its color was deep yellow, almost orange, It had an enticing fruity bouquet (apricot?, peach?, pineapple?), a taste of very rich fruit allied with that strong streak of acidity, and a long finish that reminded us of citrus fruit. When I first tasted this wine, in 1992, it was exceedingly sweet. Now, over 16 years later, it tasted virtually dry. Adele remarked that it would have been perfectly appropriate to serve it with a meal.
