Just a sample of the net and mucatel
GENERICS California Muscatel This wine varies from light to dark amber and from sweet to very sweet. In order to achieve its full muscat character it should be made from a considerably higher percentage of muscat grapes than the required legal minimum of 51 per cent. For the purpose of this Guide the wine is generic in so far as the particular muscat variety from which it has been produced is not indicated.
The Muscat of Alexandria, pre-eminently a raisin grape, is the variety most generally used for producing the wine labeled "California Muscatel:" The grape does extremely well in the San Joaquin Valley and in Southern California, particularly in the Escondido district in San Diego County. The more aromatic Orange Muscat yields higher quality muscatels, as do the delicate Muscat Canehi, or Frontignan, and the Malvasia bianca, the latter two being marketed under their varietal names.
Black Muscat or Black Muscatel The name given to high-quality red muscatels, derived from various grapes, depending on the grower. It is produced notably in Santa Clara County from Muscat Hamburg grapes and in Southern Alameda from a blend of Muscat Hamburg and Aleatico.
Use and Service-Muscats and muscatels are most appropriate when served in the afternoon and evening with cookies, cake, or sandwiches, or at dinner with a sweet dessert. The white types are also used in cooking, especially with ham, and make a refreshing drink when served in a tall glass with ice and a slice of lemon, the acidity o$ which perfectly counterbalances the sweetness of the wine.
