Amontillado is a variety of sherry wine. It is named after the Montilla region of Spain, where the style originated in the 18th century. Amontillado is a Fino or Manzanilla that started with biological ageing under flor for the first three to eight years or so, and matured further (usually longer) in an oxidative way, without flor. It is characterized by nutty aromas, tobacco, aromatic herbs and often ethereal, polished notes of oak. The fusion of two different aging processes makes Amontillado wines extraordinarily complex and intriguing.
