A sherry vinegar with the depth and complexity of the time honored tradition of solera aging - Palomino grapes grown near Jerez, Spain, and a series of barrels called criaderas. Each criadera contains vinegars with similar flavor characteristics aged for different lengths of time. When the solera, the barrel with the oldest vinegar, is tapped, it is never fully drained. The remaining vinegar is blended with the vinegar from the next youngest criadera, and so on until the youngest is topped off with fermented must. Cepa Vieja comes from a solera containing vinegar that is 25 years old with 7% acidity.
