RENSSELAERVILLE — This Helderberg Hilltown will be abuzz with holiday cheer on Saturday, Dec. 5, including a greens sale at the library, an artists’ exhibition, a community beer party, a visit from Santa, and a tree-lighting.

From 2 to 4 p.m., the Carey Institute at 63 Huyck Rd. will host its annual eggnog beer party. Visitors can sample beers made by the institute’s brewer, Greg Hostash. The Helderberg Brewery was founded with the vision of brewing beer for the local community — using and ingredients grown by local farmers— and these are Hotash’s first farm-crafted beers; he has 15 years of home-brewing expertise.

In anticipation of the brewery’s official opening in early 2016, the institute will also launch its Growler Club at the party, with membership providing start-up capital for Hotash’s breweing.

Traditional eggnog will also be served at the party, adapted from P.L. Elmore’s historic recipe. Elmore was cofounder of the institute’s forerunner, The Institute on Man and Science, along with his wife, Katherine Huyck, and their friends Winifred and Everett Clinchy.
