Named after the Montilla region of Spain, where the style originated in the 18th century,
Amontillado Sherry is unique due to its dual aging process where biological ageing occurs first under the veil of flor (also typical of Fino and Manzanilla), followed by a period where the wine is exposed to oxidation.
While there is a wide range of Amontillados, the result of this dual process tends to make sherries that are darker than a Fino but lighter than an Oloroso.
