The third annual Metrowest Brewfest will be hosted by the Holliston Historical Society on Thursday from 6:30 to 9:30 p.m. at 747 Washington St. Participants will be able to sample microbrews from more than 40 suppliers, according to an announcement on the age-21-plus event. Sponsored by Fifth Avenue Liquors, the brewfest’s proceeds go to the Holliston Business Association’s Community Action Fund, which helps local residents in financial distress. The evening will also feature two bands and food from local vendors. Tickets are on sale for $30 at Fiske’s General Store and Fifth Avenue Liquors, and will cost $35 at the door; both of the previous events sold out, the business group said on its website, www.hollistonbusinessassociation.com.
