Frozen Yogurt, Ice Cream and Chilled Salads! Plas Farm came into existence when David Williams started to diversify his farm business in the early 1980’s to produce chilled yogurts and cheeses using the milk from his herd of Freisian cows. Since then the company has developed, and has gone from producing on a small farm to a purpose built factory in Gaerwen. Plas Farm have now established themselves as one of the leading frozen yogurt manufacturers in Europe, with over 20 years experience in the market. Zero fat, probiotic frozen yogurts are currently taking Europe by storm, and Plas Farm are working hard to improve the market with top quality products, and innovative new flavours.
