The first Gutiérrez Colosía bodega was built in 1838 and it has been preserved almost as such to this day. Towards the beginning of the 20th century it was acquired by Sr. José Gutiérrez Dosal, the late great grandfather of the current Gutiérrez Colosía family. The Gutiérrez Colosía wines are produced in bodegas, or wine cellars, with an architectural style known as Nave Cathedral or cathedral-like warehouse. These arched buildings of significant height, help to expose the wines to the influence of the local climate. Its cellars are the only ones on the Puerto riverside, giving Gutiérrez Colosía a unique microclimate that offers the perfect humidity level to grow flor, and age their unique tasting Fino del Puerto. These Puerto-variation wines are traditionally lighter in oxidative flavour than those from Jerez. Juan-Carlos Gutiérrez Colosia believes his fino is best drunk fresh and chilled, so it is therefore available after only three or four years in solera. His amontillado and oloroso are bottled with greater age and are also perfect for chilling.
