Williams & Humbert was founded in Jerez de la Frontera in 1877 by Sir Alexander Williams and Arthur Humbert. The relationship between the founding families was both commercial and personal: Arthur Humbert’s sister Amy married Alexander Williams. From its beginnings, the company developed a strong international orientation and played an active role in the commercial and institutional development of Sherry. Dry Sack was introduced in 1906 and became the house’s most internationally recognised brand. The current Dry Sack Medium is based on Oloroso Yema made from Palomino and blended with Pedro Ximénez, undergoing oxidative ageing through the criaderas-and-solera system for a minimum average period of six years.
After a period under Rumasa ownership, Williams & Humbert was acquired by the Medina family in the early 1990s. The Philippine beverage group The Keepers entered the shareholding in 2018 and increased its participation to 50% in September 2022. The company is therefore jointly owned by the Medina family and The Keepers.
The principal winery complex was built in the mid-1970s outside central Jerez, covering more than 50,000 square metres and housing approximately 60,000 American-oak casks — one of the largest winery facilities in Europe. The building is included in the recognised Andalusian immovable heritage inventory; this designation should not be confused with the separate legal classification of Bien de Interés Cultural. The house owns vineyards in the historic Jerez Superior pagos of Balbaína, Añina and Carrascal.
Jalifa is currently marketed as an Amontillado VORS made from Palomino with a certified minimum average age of thirty years. Dos Cortados is currently presented as a Palo Cortado VORS, also with a certified minimum average age of thirty years, produced from Palomino originating in Añina, Balbaína and Carrascal. Older releases and commercial listings may describe Dos Cortados as VOS, but that classification relates to previous bottlings. Williams & Humbert also preserves an extensive collection of vintage Sherries dating back to 1920.
