The mirabelle is a speciality of the
French region of
Lorraine, which has an ideal climate and soil composition for the cultivation of this fruit. This region produces 15,000 tons of mirabelle plums annually, which constitutes 80% of global commercial production. There are two main
cultivars grown for fruit production, derived from cherry plums grown in
Nancy and
Metz. The Metz type is smaller, less hard, and less sweet, and has no small red spots on the skin. It is very good for jam, while the Nancy type is better as fresh fruit as it is sweeter. Since 1996 the
mirabelle de Lorraine has been recognized and promoted by the EU as a high-quality regional product, with a
Protected Geographical Indication (PGI). This label guarantees a minimum fruit size (22 mm) and sugar content, and can only be used in a specific geographical zone of production. The city of
Metz dedicates two weeks to the Mirabelle plum during the popular Mirabelle Festival held in August. During the festival, in addition to open markets selling fresh prunes, mirabelle tarts, and mirabelle liquor, there is live music, fireworks, parties, art exhibits, a parade with floral floats and competition, and the crowning of the Mirabelle Queen and a gala of celebration. == Appellation protection ==
