Oloroso ("scented" in Spanish) is a variety of fortified wine (sherry) made in Jerez and Montilla-Moriles and produced by oxidative aging. It is normally darker than Amontillado. Oloroso is usually dark and nutty.
Unlike the Fino and Amontillado sherries, in Oloroso the flor yeast is suppressed by fortification at an earlier stage. This causes the finished wine to lack the fresh yeasty taste of the fino sherries. Without the layer of flor, the sherry is exposed to air through the slightly porous walls of the American or Canadian oak casks, and undergoes oxidative aging. As the wine ages, it becomes darker and stronger and is often left for many decades.
Oloroso Sherry is also the base for many of the sweet sherries developed for the international market, such as Bristol Cream, in which Oloroso is sweetened and sometimes has the color removed by charcoal filtering to achieve a desired effect.
Olorosos are dry, not sweet. Wines labelled as "Rich Oloroso", "Sweet Oloroso" or "Oloroso Dulce" were formally banned by the Andalusian regional government on 12 April 2012. They will have to re-labelled as "Cream Sherry: Blend of Oloroso". The rules applicable to the sweet and fortified Denominaciones de Origen Montilla-Moriles and Jerez-Xérès-Sherry are:

Oloroso should be served at 12-14°C, and can be served as an apéritif with nuts, olives or figs, with game and red meats, or after a meal with rich cheeses. Sweetened Oloroso can also be taken as a long drink with ice. Cream Sherries which are sweetened Oloroso, (produced by blending with Pedro Ximénez wine), should also be served at 12-14°C and are usually served after a meal as a dessert wine. They can also be served with certain dishes, such as foie gras.
