The Rieslings of Jamesport Vineyards on Long Island's North Fork are quite concentrated and baroque in style. No doubt that they are amongst the best Riesling of New York state.
Jamesport Vineyards was founded in 1981, farming 40 acres (16 ha) of vines with sustainable farming practices.
If you bring empty Long Island wine bottles to the winery they will reward your recycling effort with a free tasting and with discount on their wines (see winery website for more info).
