Gutiérrez Colosía, 'Oloroso'

The product of the complete fermentation of Palomino grape must, Olorosos are unique in that undergo only oxidative ageing. An initial fortification to 17% by volume prevents the development of the film of flor, exposing the wine to oxygen. 

The wine slowly ages in constant contact with oxygen as it descends through the traditional criaderas and solera system. The gradual loss of water through the wooden walls of the cask facilitates a process of concentration which enables the wine to gain in structure, smoothness and complexity.

Oloroso comes from the Spanish 'scented',  this sherry variety is incredibly fragrant, typically displaying complex aromas of nuts that are complemented by balsamic, leather, and truffle nuances

Flor refers to film forming yeasts that grow on top of some sherries, preventing oxidization while still capable of fermenting the wine. The yeasts will only form in the narrow alcoholic range of 14.5% to 16%, and cannot be grown in stainless steel tanks.
