Cornell Cooperative Extension of Delaware County will host its 89th annual Dairy Tour Tuesday.

Participants are expected to provide their own transportation between stops. Lunch will not be provided, but Polar Bear Homemade Ice Cream will serve refreshments.

The tour begins 10 a.m. at Sunny Alp Farm at 221 Wickham Road in Stamford.

Owned by Swiss immigrant Rudy Landolt and Nina Hade, the farm produces organic milk from grass-fed cows and ships to Maple Hill, according to a media release.

Two silos and a milking parlor were recently constructed, and a new grazing system established.

At noon, Dave and Carolyn Post and their daughter and son-in-law, Carolee and Allen McClure, will host visitors at Pineyvale Farm at 3949 Town Brook Road in Hobart.

Guides will discuss how the farm has transitioned throughout its more than 220-year history and eight generations of family ownership.

The dairy barn was updated in the aftermath of Hurricane Sandy, and the family has added an additional barn for dry cows and heifers since hosting the tour last year, according to the release.

Delaware County Dairy Princess Theresa Cerosaletti and her court will serve milk and ice cream discuss recent activities of the county dairy promotion committee.

The third and final stop of the tour is SRJF Inc., at 31850 State Highway 23 in Stamford.

Frank and Marc Albano and their families will host visitors at 1:45 p.m. to tour the farm’s recent expansion and new milking parlor, according to the release. They will also discuss how the cows transitioned from tie stalls to free stalls and how new cow-monitoring equipment keeps operations running smoothly.
