Reply To: Is Sherry Cask Scotch kosher?

Super, super over-simplified: If treif wine, especially fortified wines with a high sugar content (remember all that yayn nesech stuff) soaks into the wood barrels in which it was aged and those barrels are subsequently used to age schnops and the wine in the wood is released and mixes with the schnops, the schnops is arguably “contaminated”. Again, over super simplified analogy.
