Gonzalez Byass was founded in 1835 by Manuel Maria Gonzalez and remains in family hands today. Their first product was the iconic Tio Pepe, and they now present a full range of Superior and V. O. R. S. (wines aged for more than 30 years) sherries. With holdings and contract managed vineyards, all in the Jerez Superior area of the Jerez DO, they control over 10% of the DO sherry production. 90% of the grapes are Palomino and 10% Pedro Ximenez. They are the only winery in Jerez to grow their own PX. The vines are planted in the white Albariza soil, rich with clay and a high chalk content which is excellent for retaining moisture. These soil conditions, combined with over 3,000 hours of annual sunshine, fresh, humid breezes from the west and warm, dry breezes from the east and the proper amount of rainfall make ideal growing conditions for the grapes. All of the sherries have a distinct character produced by either the “Flor” or “Oloroso” methods and are all aged in the solera system.
