Marqués de Terán Winery is located on a hillock in the upper part of the Town of Ollauri. It has been conceived to take the maximum advantage of gravity in the reception and transport of the grape, avoiding the use of pumps. Its architectural structure is integrated in the landscape thanks to its cellars, that have been excavated into the slopes. Constant investment in Research and Development is one of its hallmarks and is present throughout all the winemaking process, with pioneering technologies in Rioja like prefermentative criomaceration and pissage fermentation tanks. Innovation also lead us to be the World's first winery in using clean geothermal energy as a main source for winemaking.
