Came across Kings County Distillery - "Licensed on April 14, 2010,
Kings County Distillery is New York City’s only operating whiskey
distillery, the first since before prohibition. Kings County makes
hand-crafted whiskey, bourbon,
and moonshine."

Looks like they only have 200 ML flasks of moonshine (corn whiskey)
available at present. List of NY stores where it's available plus a
couple tastings if anyone's gonna be in the area.
