Brandy is made from early grapes in order to achieve higher acid concentration and lower sugar levels. Base wine generally contains smaller amount (up to 20 mg/l) of sulphur than regular wines, as it creates undesired copper(II) sulfate in reaction with copper in the pot stills. The yeast sediment produced during the fermentation may or may not be kept in the wine, depending on the brandy style. Brandy is distilled from the base wine in two phases.
