The magic veil of yeasts

The most distinctive feature of Montilla-Moriles, what makes the region’s wines special, is the humble veil of yeast that covers the surface of the wine inside the oak butts. The famous flor. Formed by live yeasts, this layer of flor is responsible for the natural process known as biological ageing.

Ageing under the veil of flor takes time. It must be left to develop: the yeast protects the wine and at the same time imparts that genuine style and character. Pérez Barquero’s renowned finos and amontillados are born as a result of the flor and the passage of time.
