Welcome aboard.
I did some Googling for ya in regards to where you can find the ST Chokolat
"In Manhattan, New Beer Distributors just off Delancey is a good place to start, as is the LES Whole Foods, with their whole "beer store" section. All the WF stores have reasonably good selections, too.
Out in Brooklyn, both Bierkraft and Thrifty/American (Park Slope and Carroll Gardens, respectively) should have it, or tell you when they'll have it."
