Verjus was one of the main cooking base in the middle ages. Up Until recently, it was a common sight on the countryside of south west France. Verjus are the aborted grapes which never ripened as well as the juice obtained from them. Just after the WWII, lemon was still uncommon as well as a luxury, Verjus on the other hand was easily available and, if not for the women of the farms, would have been dealt with by the birds or vine workers in search of a few more liters of 'wine'.
Our Verjus du Périgord is made of pasteurized unriped grapes juice, and therefore needs to be kept in the fridge once open. No acidification or E number is added to the Verjus. It is traditionally used to deglazed Foie Gras and in dishes involving game and duck. In truth, its use is endless as well as it being a very healthy product.
