Hugel & Fils produces its high-end wines from its own vineyards, and also operates a négociant business, which sources additional grapes under long-term contract from various growers. Hugel is highly export-oriented, with almost 80 percent of the wines produced being exported.
Hugel & Fils hold slightly over 25 hectares (62 acres), all located around Riquewihr and almost half in vineyards allowed the Alsace Grand Cru designation. In addition, grapes from over 100 hectares (250 acres) of Alsace vineyards are bought in for the négociant business.
For the top wines, Riesling is grown in the Schoenenbourg vineyard, Gewürztraminer in Sporen, and Pinot gris and Pinot noir in Pflostig.
Hugel & Fils does not use the Alsace Grand Cru designation for any of their wines, although most of their top wines come from Grand Cru vineyards. Instead, Hugel uses its own quality designations. Although Hugel was a pioneer in sweet Alsace wines, only wines clearly marked as late harvest wines or special cuvées have noticeable residual sugar; the wines of the regular range are always dry. For wines at the Tradition level and above, Hugel typically releases the wines when they are judged to be ready for sale. Thus, at a given time, different vintages may be in distribution for wines of different grape varieties, and the sweet wines are often sold with several years of bottle age.
