The things you find in a kitchen drawer...

Foodie,

I would love the information if you can remember it being that I grew up just miles from there.

Here is what I found using "Oldest Winery in the US" as search:

Winemaking is an ancient and honored art, and nowhere is this more evident than at Brotherhood, America's Oldest winery, located in the picturesque village of Washingtonville, NY. The winery was established by a European emigre, John Jaques, who produced the first commercial vintage in 1839.
Brotherhood has been in continuous operation since that time - making the winery the oldest in the United States!

You won't believe our underground cellars!
In 1886 the winery changed hands. Mr. Jesse Emerson and his son expanded the facility, adding the "landmark" stone building with additional underground cellars that are the largest in the country.
Having survived prohibition by the sale of sacramental wine, the winery again changed ownership around 1921. During the "Farrell" era the winery underwent dramatic changes - major expansion, the beginning of a visitor tour operation and the creation of a broad range of award-winning wines. Brotherhood remained a "family business" until a change of ownership in January of 1987.

Brotherhood Winery is listed in the New York State Register of Historic Places and is listed as a National Historic Landmark.
