Is there a halachic reason that there is no Kosher boxed wine on the market? Is there something about a boxed wine or the plastic container that prevents kosher wine from being stored in there?
I couldn't find any available, and I couldn't come up with a Halachic reason that it wasn't possible. The basis of the question is storage, and I can advise on how to prolong that, but I can't answer the basic questions. I appreciate any insight.
