Food pairings: dry versions go well with fish, chicken and pork dishes. The crispiness of a Riesling works very well with tuna and salmon while the acidity level intermingles with the slight smokiness of the eel and cuts through the layers of spicier Japanese foods.
Districts: the classic German grape of the Rhine and Mosel, riesling grows in all wine regions. Germany's great Rieslings are usually made slightly sweet, with steely acidity for balance. Riesling from Alsace and the Eastern U.S. is also excellent, though usually made in a different style, equally aromatic but typically drier (not sweet). California Rieslings are much less successful, usually sweet without sufficient acidity for balance.
Typical taste in varietal wine: Riesling wines are much lighter than Chardonnay wines. The aromas generally include fresh apples. The riesling variety expresses itself very differently depending on the district and the winemaking. Rieslings should taste fresh. If they do, then they might also prove tastier and tastier as they age.
