William Chase, Founder of the Williams Chase Distillery
William Chase is the founder of the Williams Chase Distillery, producing vodka and gin made from potatoes.
At the age of 20, William bought his father's farm, and having supplied supermarkets with potatoes, he wanted to diversify the business. He went on to build a potato crisp factory, founding Tyrrells Potato Chips, which he sold in 2008 for £30 million.
William set up the Williams Chase Distillery in 2007 and started producing a premium vodka made from the potatoes that were too small to be made into potato crisps. Today the distillery makes a range of vodkas, gins and liqueurs.
