To our Island Community,

For more than a decade, this little winery has been a labor of love. What started as a small family venture grew into something far more meaningful—a place where neighbors gathered, friendships formed, celebrations were shared, and memories were made.

From the very beginning, this space was never just about wine. It was about community.

Over the years, we’ve made the decision to keep the winery open not because it was a strong business model—it hasn’t been—but because it felt important. On a small island like ours, places to come together matter. And it has meant everything to us to be able to offer that.

That being said, we’ve decided that this will be our final season.

While this may no longer work for us, it could still have a future. If there is someone in the community who feels inspired to step in and carry it forward in their own way, we would be open to that conversation.

In the meantime, we are looking ahead to one last season—business as usual, doors open, glasses full. We hope you’ll come out, spend time here, and help us celebrate everything this place has been.

To everyone who has supported us over the years—our patrons, friends, neighbors, and family—thank you. Our staff has been dedicated & has poured their hearts & souls into this place. Thank you to everyone who has worked, volunteered, and contributed. This list is long, and you know who you are.

We’re incredibly grateful for the memories, and we’re excited to make a few more with you this season.

Cheers 🍷
