Muscat Blanc à Petits Grains is a white wine grape of Greek origin that is a member of the Muscat family of Vitis vinifera. Its name comes from its characteristic small berry size and tight clusters. It is known under a variety of local names such as Moscato bianco, Muscat blanc, Muscat Canelli, Muscat de Frontignan, Muscat de Lunel, Muscat d'Alsace, Muskateller, Moscatel de Grano Menudo, Moscatel rosé and Sárgamuskotály.
While technically a white grape, there are strains of Muscat Blanc à Petits Grains vines that produce berries that are pink or reddish brown. The same vine could potentially produce berries of one color one year and a different color the next. These strains are more prevalent in Australia, where the grape is also known as Frontignac and Brown Muscat. South Africa's Muskadel strain tends to show the same darker characteristics. Variants where the differing grape colour is stable are typically classified as separate grape varieties Muscat Rouge à Petit Grains for red skin colour and Muscat Rose à Petit Grains for pink skin colour.
In Greece, the grape is found on the island of Samos and near Patras in the Peloponnese. On Samos, it produces a Vin Doux Naturel, aromatic dry white wines and a Liastos or straw wine. The high quality wines come from vineyards between 500 and 1000 metres above sea level. Near Patras it is used to produce a Vin Doux Naturel.
In Italy, the grape is the most widely planted member of the Muscat family and is most commonly known as Moscato Bianco. It is the oldest known variety grown in Piedmont and is the primary component of the Asti and Moscato d'Asti wines, as well as for the aromatized and fortified vermouths. It is also commonly used for fortified dessert wines as well as the semi-sparkling Frizzante.
In France, the grape is used as a blending grape with Grenache blanc and Muscat of Alexandria in vins doux naturels wines from the Frontignan area such as Banyuls, Côtes d'Agly, Grand Roussillon, Rivesaltes and St-Jean de Minervois.
