from a neewb...(me)
Of course it ages...1 year from now it is one year older, and so is the bottle...and yourself as well....and come to think of it, so is the glass, etc., etc
Seems the real question is ..."does it continue to improve/change"? Very little it appears is the consensus. I've had the same question. Thx. I have come to understand that most change (99.8%)...happens in the barrel/cask, and the age statement is the age of the youngest vat placed into the bottle?
