US-based dairy business Butterworks Farm has been acquired by Anthony Calderaro, Ania Kuniej and Joseph Calderaro.

Financial details were not disclosed.

The Vermont dairy farm, which produces organic dairy products from the milk of its 76 Jersey cows, had been run by founders Jack and Anne Lazor for 48 years, along with their daughter Christine Lazor and her husband, Collin Mahoney.

The Calderaro family “have ambitious plans to expand Butterworks Farm’s reach, aiming to offer their healthy, grass-fed organic products to more customers across existing and new markets,” according to a statement.

The farm itself is comprised of 400 acres of pastures and hayfields as well as a processing plant, with around 15 employees. Butterworks Farm produces yogurts, kefir, heavy cream and buttermilk products from its on-farm creamery all year round.

“We are very excited to become the new owners of this 100% grass-fed organic dairy farm and to continue the cherished tradition started by Jack and Anne Lazor. We share their passion and vision for people, animals and nature living in balance,” said the new owners.

Butterworks is capable of on-farm processing of 4,000 to 5,000 quarts of milk weekly in the form of organic, grass-fed yogurt, buttermilk and kefirs all with live and active cultures, according to its website.

These products, and a small amount of heavy cream, are available throughout Vermont and most of the US north east.

Meanwhile, another US kefir maker has seen its largest investors make another push for the resignation of its chief executive.

Ludmila and Edward Smolyansky, the largest shareholders in Lifeway Foods, filed a consent statement to unseat the company’s current board of directors, including CEO Julie Smolyansky.

The shareholders announced the filing with the US Securities and Exchange Commission yesterday (13 August).
