Have had it from the NorthEast US - I want to say Rhode Island (not upstate NY) and from Vancouver, BC.
Drink it more like an after dinner liqueur, than a glass of white wine. Trust me.
I learned how to wine taste with Niagara Icewine and Cabernet Franc.
Like it very cold, small amounts. It’s very sweet.
I’m actually thinking of buying the shot glass ice molds for this.
