vinegar
Question
Suppose someone has a sandwich at Subway. Is it okay to have mustard even if the mustard has vinegar? If the vinegar in the mustard is made from grapes, does it render the mustard non-kosher? This question applies to other condiments and products that contain vinegar that may be made from grapes. Thank you.

Answered by Aaron AbadiIf it just says "vinegar," it is OK. If it contains "wine vinegar," stay away from it. If you want to be sure, email the company. AA
