The height of the winery's wines is the Tokaj Aszú, the free run wine of Tokaj.The Tokaji Aszú is the noblest sweet wine in the world. Its development involves the benign influence of noble rot. It is the wine for which Tsar Peter the Great of Russia sent legions of Cossacks to watch over the wineries of Tokaj and the roads through which it was transported to St. Petersburg, where it was served at the table of Catherine the Great. Voltaire said of this wine, "This wine invigorates every fibre of my brain and, deep in my soul, produces a charming glint of intelligence and good humour”.
