Can one drink Scotch whiskey without Kosher supervision?
• ANSWER: Single malt scotch may be used without concern if it was not aged in sherry casks. The permissibility of Scotch that was aged in sherry casks is the subject of differing opinions among later Poskim (Rabbinic decisors). One cannot always tell, based upon the label if a particular bottle of scotch was aged in sherry casks. Blended Scotch – Rabbi Moshe Feinstein ZT”L ruled that blended scotch is permitted, but it is noteworthy that in issuing that ruling he also gave reasons why a “ba’al nefesh” (loosely translate as: a person who cares more for his soul than for satisfying his earthly desires) should not drink blended whiskies. You should consult your local Orthodox Rabbi about what to do with regard to both single malt and blended scotch.
