In California, Riesling lags far behind in popularity to Chardonnay and is not as commonly planted. A notable exception is the growing development of high quality Late Harvest dessert wines. So far, the Late Harvest wines most successfully produced are in the Anderson and Alexander Valleys where the weather is more likely to encourage the needed botrytis to develop. The Riesling that does come out of California tends to be softer, fuller, and having more diverse flavors than a "typical" German Riesling.

Riesling is a white grape variety which originated in the Rhine region of Germany. Riesling is an aromatic grape variety displaying flowery, almost perfumed, aromas as well as high acidity. It is used to make dry, semi-sweet, sweet and sparkling white wines. Riesling wines are usually varietally pure and are seldom oaked.

Riesling has a powerful and distinctive floral and apple-like aroma that frequently mixes in mineral elements from its vineyard source and is often described as "racy." Its high natural level of Tartaric acid enables it to balance even high levels of residual sugar.

Riesling gives wine lovers the finest example of the important complementary role that sugar and acid play in a wine’s overall balance. Indeed, a great Riesling is exactly that, a stunningly graceful contrast between the two. Rounding out the package are the signature floral fruit characteristics that combine perfectly with the grape's natural sugar-acid balance. This gives Riesling the potential to age gracefully for years, becoming more supple and luxurious, with petrol-like qualities.

The most expensive wines made from Riesling are late harvest dessert wines, produced by letting the grapes hang on the vines well past normal picking time. Through evaporation caused by the fungus Botrytis cinerea ("noble rot") or by freezing, as in the case of ice wine water is removed and the resulting wine offers richer layers on the palate. These concentrated wines have more sugar (in extreme cases hundreds of grams per litre), more acid (to give balance to all the sugar), more flavor, and more complexity. These elements combine to make wines which are amongst the most long lived of all white wines.
