Abstract

Vinjak je jako alkoholno piće koje se dobiva destilacijom vina i dozrijevanjem u hrastovoj bačvi. Vino se dobiva od bijelih sorti koje imaju veći prinos što rezultira većom koncentracijom kiselina. Kiseline utječu na pH vrijednost koja bi trebala biti oko 3. Niski pH omogućuje proizvodnju vinjaka bez sumporenja što utječe na bolju kvalitetu i kakvoću vinjaka. Destilacija se može obavljati na jednostavnim destilacijskom uređaju, alambicu, s time da se radi dvostruka destilacija ili se može raditi jednostruka destilacija na složenom destilacijskom uređaju s kolonom i deflegmatorom.

Abstract (english)

Brandy is a strong alcoholic drink obtained by distilling wine and maturing in oak barrels. Wine is obtained from white varieties that have a higher yield, which results in a higher concentration of acids. Acids affect the pH value, which should be around 3. Low pH enables the production of brandy without sulfidation, which affects the quality of brandy. Distillation can be performed on a simple distillation device where double distillation must be done or on complex distillation device with column and dephlegmator performing single distillation.
