Colavita's range of Balsamic vinegars are deep, rich brown in colour and originate from Modena in Italy, made from the concentrated sweet juice of white grapes. It is then fermented in a succession of barrels for between five to 30 years. Colavita 25 Gran Riserva is considered as precious as the finest liqueurs and thanks to its strong flavour, it only needs to be used in small amounts.
