The white grape comes from the border area Italy / Switzerland, Synonyms are Großer Lafnetscha, Kleiner Lafnetscha, Lindauer, Malans, Malanserrebe, Malanstraube, Malansertraube, White Malanstraube and Zürirebe. The variety was mentioned in a document from Chur Cathedral in 1321 (according to another source, as early as 926). The name of the wine of the same name is derived from the “Completorium” evening prayer, after which the strong wine was formerly drunk by the monks of the Chur cathedral chapter during Lent.
The parents of the variety are unknown. Allegedly the variety of Benedictine monks of the Pfäfers monastery from St. Gallen from Italy to Malans in the canton Grisons introduced. The Italian origin is supported by the fact that there is a completer between the Italian varieties Marzemino and Pignolo Spano are related. In Switzerland, Completer becomes a group of grape varieties Old plants counted. Through several DNA analysis the lineage of some of these varieties has been clarified. From probably a natural crossing Completer x Humagne Blanche is Lafnetscha emerged. From crosses between Completer x Bondola are the varieties Bondoletta and Hitzkircher emerged.
The medium to late ripening vine produces an alcoholic, acidic wine with aromas of quince and orange blossom. It was almost extinct in the middle of the 20th century until a vine was selected and propagated from an old stock. This vine still stands on a wall at the "Completerhalde" in Malans. There are small areas of cultivation in the cantons Grisons (2 ha), Ticino and Zurich, In 2002 Visp Wallis discovered a stock together with the Lafnetscha variety. In 2010 only three hectares of vineyards were shown (Statistics Kym Anderson ).
