The project of Mathilde Cousin, daughter of the infamous Anjou vigneron Olivier Cousin, Le Vinaigre des Cousines produces organic wine vinegars using old-vine Cabernet Franc and Chenin Blanc. Following a process that echoes the time and care required to make a great wine, the vinegars are produced entirely naturally. Observing the ancient Orléans method, the wine is aged in partially-filled, open-topped barrels for between three and six months, allowing it to oxidise and undergo a natural second fermentation, during which the alcohol is converted into acetic acid, giving the vinegar its piquancy. As with the Cousin family wines, nothing is added or removed at any stage. Full of depth, balance and complex flavours and aromas, they are a world away from their industrially produced counterparts.
