The scene at Pindar Vineyards Friday was a little out of the ordinary. Instead of out-of-towners sampling chardonnay and pinot grigio, a health care organization was offering a free clinic in the Peconic tasting room, where bilingual employees took health histories, tested blood pressure, gave nutritional consultations, handed out specialty referrals and scheduled follow-up appointments for about 40 local agricultural workers and their family members.
