Amontillado is a kind of dry sherry which is darker than Fino but lighter than Oloroso, maturing with a cap of flor and then expose to the air for further oxidation due to the loss of flor. Toasted almond and hazelnut are the classic aromas for Amontillado casks.
Colour: Brilliant juglans nigra
Nose: Very rich and fruity. Good sweetness with notes of walnut and almond. Slight toffee and a touch of oak.
Palate: More exotic and soft sherry with a hint of caramel. The finish is gently long with nutty and pepperiness
