Name (pronounced Proschek) for a branded wine from Croatia, which is produced in Dalmatia (where it is also produced on the two islands of Hvar and Vis) and Istria. The etymological meaning of the designation is not certain, but the name is probably derived from the Croatian adjective prošli (last, last), which indicates the late harvesting of the grapes used for this wine. There are several varieties of these mainly sweet dessert wines, which can vary greatly in colour, aroma and quality. Mostly these wines are characterised by a high content of residual sugar, but also fresh acidity.
The white varieties Bogdanusa, Maraština(Malvasia Bianca Lunga), Pošip Bijeli and Vugava, but also red varieties such as Plavac Mali (especially on Hvar), as well as in mixed form, are mainly used for this purpose. Depending on the varieties used, this results in amber to brown-red wines. High quality products are produced from dried grapes according to the method of a passito, some similar to a port wine. By adding grape must concentrate and, more rarely, sprites, a relatively high alcohol content of 15 to 17% vol. is usually achieved. Some large wineries in Sibenik and Split market these wines under the name Dioclecijan after the Roman emperor Diocletian (243-316), who was born in Dioclea on Dalmatia.
