What it is:  Brandy
Brandy (from brandywine, derived from Dutch brandewijn—"burnt wine") is a spirit produced by distilling wine, the wine having first been produced by fermenting grapes. Brandy generally contains 35%–60% alcohol by volume and is typically taken as an after-dinner drink. While some brandies are aged in wooden casks, most are colored with caramel coloring to imitate the effect of such aging.
