Monsey is just over the NY State line from some super ritzy NJ towns like Saddle River, so unless the economic conditions change radically in 1/4 mile, I would suspect the store caters to wealthy people for the most part.
I had an Israeli wine last year, a white blend, that was excellent but I cannot remember the producer.
When I was in retail, we sold a ton of Kosher wine but the sales were nor for religious reasons, but to a clientele niche that loves sweet wine. Mani, Mogen D., etc.
Monsey has a Wikipedia entry - quite interesting. They have some Lenape Indian sites there but I could not spot them using Goggle Maps or Google Earth as Google uses summer photography in which the greenery hides anything of interest. Dopes. dc.
