The Berecz family house has a two centuries old cellar partially carved into the rock where the wines ferment and mature in oak casks. The winery produces around 11,000 bottles annually, including dry and semi-dry Furmint and Hárslevelű, some from single vineyards or dülős, late harvest wines, Szamorodni, and hand-picked aszú wines.

The grapes are whole cluster pressed. Fermentation occurs with native yeast without going through the secondary malolactic fermentation. The must is then racked and put into French and Hungarian oak barrels. Aging is on the lees. Most of the barrels are about 4 to 10 years old with a few new Hungarian for the Furmint. The Hárslevelű has no new oak to preserve the fruity flavors of the grape without being overwhelmed by oak.

In 2014, Stéphanie has been awarded by her fellow winemakers the prestigious title of „winemaker of the winemakers”.
