Rhine wine refers to dry white wines produced along the Rhine valley in Germany. Also, it is important to note that based on the US law, any white wine with an alcohol level lower than 14 percent is also considered Rhine wine.

WineFrog explains Rhine Wine
Grown in the temperate weather along the rocky soil of Rhine valley, Rhine wine derives its characteristic mineral essence from the regional soil. With variations in the type of white grape used for fermentation, there are quite a few types of popular Rhine wine. Some of the well know names include: Riesling, Kabinett, Spätlese, Auslese, Müller-Thurgau and Gewürztraminer. The variation in taste of each Rhine wine is achieved by an arduous viticultural process. Things like the timing of grape harvesting and period for which the grapes are allowed to grow on the vines, greatly determine the taste of the wine produced. Rhine wine can be identified by a signature bright, crisp and sometimes sweet flavor. Similar techniques are used while producing Rhine wine elsewhere.
