Beer After Pesach in New York
As is well known, many brands of beer sold in New York City and surrounding counties are distributed by a Jewish owned company. Although a number of Rabbonim have worked with the company to affect a mechiras chometz, long standing STAR-K policy has always been not to rely on a mechira in these types of situations. Each individual should consult his Rav for guidance.
