These days, grapes are cultivated almost exclusively on the slopes of the Moselle river. The grapes that do grow on this soil, known for its acidity, are taken to the wine press. There are seven typical wines: Elbling, Rivaner, Auxerrois, Pinot Gris, Pinot Blanc, Riesling and Gewürztraminer, plus a small quantity of rosé wines: Elbling Rosé, Pinot Rosé and Pinot Noir. Not to mention the large quantity of sparkling wines, known as 'Schampes', which are very popular with locals and visitors alike.
There is a significant difference between a grape festival and a wine festival. Grape festivals are usually held in October, as a thanksgiving for a good grape harvest. A 'grape queen' is usually elected and, to the accompaniment of music, paraded through the local town wearing sumptuous clothes and handing out wine to onlookers, as in Grevenmacher, for instance. In Schwebsange, the grape festival boasts the unique feature of a town fountain supplying wine instead of water.
Wine festivals are village events usually held in spring, on the premises of local wineries or outdoors under large marquees. They feature live music and traditional food accompanied by wine (and beer).
On 'Proufdag' (tasting day), the grape harvest and wine marketing take on a more professional tone. Between May and June, each winery can open on its cellars on a scheduled day, during which it organises tastings of its latest products. Even though the top varieties have not reached maturity by this stage, connoisseurs are able to make a few educated forecasts which wine, by autumn, will have become a Grand Premier Cru!
