| Abstract | Vino je poljoprivredno prehrambeni proizvod, dobiven potpunim ili djelomičnim alkoholnim vrenjem masulja ili mošta, od svježeg i za preradu u vino pogodnoga grožđa. Bolestima vina smatraju se promjene do kojih dolazi uslijed djelovanja mikroorganizama koji razgradnjom pojedinih sastojaka stvaraju nove štetne sastojke vina. Vino je osjetljivo prema raznim faktorima i sklono kvarenju. Neki od faktora potječu od grožđa, ali najčešće se javljaju za vrijeme čuvanja vina. Kvarenja dijelimo na bolesti i mane vina. Bolesti su zarazne i prenose se sa vina na vino. Osnovne bolesti vina, koje nastaju djelovanjem raznih bakterija i gljivica, su vinski cvijet, octikavost, zavrelica i manitno vrenje, oksidacija, sluzavost te gorčina vina. Najčešće mane vina, koje nastaju djelovanjem raznih kemijskih procesa i enzima ili stranih tvari su miris vina po sumporovodiku, miris po drvu (na bačvu), miris po plijesni, bakreni, crveni, smeđi (posmeđivanje), crni (plavi), sivi i bijeli lom. |
| Abstract (english) | Wine is an agricultural food product, obtained through full or partial alcoholic fermentation of fresh grapes or grape grape juice from fresh processable grapes. Wine diseases are considered the changes that occur through the action of microorganisms which create new harmful ingredients through the degradation of the individual wine ingredients. Wine is sensitive to various factors and prone to deterioration. Some of the
factors come from grapes but most develope during the storage of wine. Deteriorations are classified as diseases and defects of wine. The diseases are infectious and are transferred between wines. Basic diseases of wine, which are caused by bacteria and fungi, are the wine flower, acetic tinge, lactic acid and mannitic fermentation, oxidation, wine mucus and bitterness. The most common defects of wine, which are products of various chemical processes and enzymes or foreign substances, are hydrogen sulfide smell, wood smell (barrel smell), the smell of mildew, copper, red, brown (browning), black (blue) , gray and white fracture. |
