Good White German, or better from ....

[hotwine]

Tell your local wine merchant that you would like to buy at least two bottles of a good quality Mosel-Saar-Ruwer Auslese. Chill them both thoroughly before offering a glass to your lady. You'll go through the first bottle quickly, and can pause to slowly enjoy the second.
The MSR is made from the Riesling grape, along the banks of the Mosel River and its tributaries in SW Germany. The Auslese is made from selected clusters of grapes, and tends to be sweeter than an ordinary Riesling made as a table wine. Beerenauslese and Trochenbeerenauslese and Eiswein are sweeter still, much more expensive and best suited to serving as dessert wines, in my opinion. You can learn more about the wines of Germany by checking the postings on this Board under Rieslings, and by searching on the Internet under the keyword Riesling.
