Gonzalez Byass, a family company, now has international renown as wine and brandy de Jerez producing vintners. The company is proud of the quality and variety of its range of products, emphasising the sherry Tio Pepe (the world leader in sales of Fino), the brandy Soberano (the leader in Spain, its country of origin) and Lepanto, with its characteristic flask, designed by the Royal Factory at La Granja. The reason for the success of Gonzalez Byass is due to its undertaking to provide quality, the axis of the corporative philosophy of the firm that has led it to invest considerable amounts in wine growing, vinification and aging. Palomino grapes are from the Jerez Superior area, where the best "albariza" land is (very limy white earth). The company own 700 hectares of vineyards located in the best spots in the zone: Macharnudo, Carrascal and Burujena. Gonzalez Byass was the first firm in the area to set up a modern programme to research winegrowing, in which it studies clonal selection and implements scientific quality control methods. It has its own nurseries and is the first and only company in the area to make this undertaking as to its vineyards. Gonzalez Byass is not known as a company that loves its wines in vain.
