These complex vinegars come from the Bai Penedes region near Barcelona in Spain. They are made from a high-quality wine base and slowly acidified using an artisanal method similar to the one used in the Spanish solera system for making sherry.
The cabernet variety has a bittersweet quality and marries well with freshly shucked oysters, vinaigrettes and in reductions for sauces.
The chardonnay style has a smooth, sweet-sour flavour that is particularly good as a flavouring for fish and shellfish and in vinaigrettes.
