About Grindstone Island Winery
When your route brings you through Clayton, Grindstone Island Winery gives you another way to experience the Thousand Islands: arrive with time, taste deliberately and pay attention to what makes this producer different. Set your map for 42811 Schoolhouse Road, Clayton, NY 13624. Then treat the rest of the day as flexible rather than stacking too many tasting reservations around it. Grindstone Island Winery is a small family winery on a St. Lawrence River island, with more than 2,000 vines planted across roughly three and a half hillside acres.
Reaching the tasting room is part of the experience, so boat or shuttle logistics deserve as much planning as the tasting itself. Wine travel in this part of New York is intentionally slower. Properties are spread across the region, and some operate seasonally or by appointment. Build the winery into a broader day around the river or nearby towns. For a first visit, let the winery choose at least part of the experience.
Staff can point you toward the wines that are drinking well now and explain how the current releases fit together. Access to Grindstone Island Winery is more seasonal or logistics-sensitive than a standard roadside tasting room. Confirm the schedule and any transportation details before departure so the winery can be the highlight of the day rather than a missed connection. Wino Notion would use Grindstone Island Winery as a conversation stop: a place to ask where the fruit comes from, how the wines are made and what the winery wants a first-time visitor to understand. If Grindstone Island Winery becomes one of your priority stops, leave enough time to enjoy the tasting rather than treating it as a quick check-in. The best wine-country memories usually come from the conversation, the pace of the day and one or two wines you understand better when you leave.
