Stonyfield Farm

Stonyfield Farm, also simply called Stonyfield, is an organic yogurt maker located in Londonderry, New Hampshire, USA. Stonyfield Farm was founded by Samuel Kaymen in 1983, on a 19th-century farmstead in Wilton, New Hampshire, as an organic farming school. The company makes the number-one selling brand of organic yogurt and number-three overall yogurt brand in the United States, according to Fortune magazine. It owns brands including YoBaby, YoToddler, YoKids and Oikos.

In 2001, Groupe Danone, a France-based food product company whose brands include Evian bottled water and Danone/Dannon yogurt, purchased an initial 40% of Stonyfield shares. This was followed in late 2003 with an additional purchase such that Group Danone now owns about 85% of Stonyfield shares.

Gary Hirshberg is chairman and former president and CEO of Stonyfield Farm.

Through its Profits for the Planet program, Stonyfield gives 10% of profits to environmental causes. Its milk comes from New England and Midwest dairy farmers through the CROPP (Organic Valley) cooperative.

In 2003, Stonyfield Farm acquired Brown Cow.

In 2006, Stonyfield entered the French market with its Les 2 Vaches (The Two Cows) brand. It also expanded to Canada, with yogurt produced in Quebec. In June 2007, Stonyfield Farm launched its first brand in the UK, Stony, Yogurt on a Mission, though the line has since been discontinued. An organic yogurt brand named Glenisk was also successfully launched in Ireland.

Stonyfield Farm supplies much of Trader Joe's yogurt on the East Coast.
