Whiskey does not improve once bottled. Unlike wine. It only improves in the barrel. Not the bottle.
Due to the recent discovery of a forty year old bottle of Dewars 90 proof Scotch Whiskey by my Dear Neighbor Lady gifted to me, we’ll just have to agree to disagree. I’ve never had smoother scotch. At any price that bottle was the finest
scotch I’ve ever had.
Correct. And yet my local liquor merchant refuses to sell whiskey in barrel format.
That theory does not play out in real life. It does get smoother in the bottle. Charred wood will age the spirits but glass can still allow separation of chemicals especially if one opens the container for a short period of time periodically to let the lighter more volatile gases escape. of course generally the glass should be stored in a cool dark location.
