how much is the guinness family worth

The Guinness family is currently worth approximately £856 million, which is around USD 1.13 billion as of 2025. This net worth places them as one of the wealthiest families in the United Kingdom. Their wealth comes not only from the brewing empire they originally built but also from diversified investments including property, agriculture (notably the Elveden estate farm which produces about 10% of the UK’s onions), and significant holdings in the multinational drinks company Diageo, which owns the Guinness brand among others. The family's fortune is primarily held by the Iveagh line, headed by Arthur Edward Rory Guinness, the Earl of Iveagh. Despite not having sole ownership of the Guinness brand since it merged into Diageo, their retained stake in the company remains a key source of their wealth.
