I recently noticed that the bottle of Kedem Kosher grape juice that I purchased has a notice on the label which reads 'FOR SACRAMENTAL PURPOSES ONLY'.
I assume this means that it's being sold to be used only for Kiddush, Havdalah or the Four Cups at the Seder.
Why is it in the company's interests to sell it in this way? Does it confer some legal, regulatory or tax advantage?
[Tangential bonus question: What happens if I want to drink it for other, non-sacramental purposes?]
