Liqueurs can be and are made from any base spirit. Likewise, the range of flavours featured is as wide as the world of flavours itself. From one beautiful flavour (e.g., the cassis berry in creme de cassis) to complex harmonies of flavour (e.g., the 135 herbs in Chartreuse), liqueurs run the gamut. While traditionally liqueurs are sipped alone, bartenders rely on their ability to act as a spirits modifier in cocktails.
