Ellsfarm and Sheep Dairy on the top of Clarry Hill in Union has taken 15 years to reach the milestone of producing a value-added dairy product from its flock of sheep. Plain, blueberry and maple flavored yogurt, made at the 63-acre farm, will be offered to visitors to sample at Open Farm Day on Sunday, July 25 from 10 a.m. to 6 p.m.

For the last 10 years, Ellsfarm has produced lamb for local stores and restaurants, but this new product will launch a diversification and make the farm more sustainable. Sheep traditionally provide wool and meat, but sheep milk products are more rare in the United States; only about 100 sheep dairies exist. Maine has two sheep dairies and Ellsfarm is the oldest — seven years to date. In the past, Ellsfarm’s sheep milk was sold almost exclusively to Appleton Creamery where it is made into award-winning cheeses.

At this annual event the yogurt will be offered for sale along with many other farm products. There also will be refreshments and free children’s activities. For more information call Perry Ells at 542-3941.
