You know your man, PB.

Luca should have smelled a rat when Philip Tattaglia offered him some Scotch--"prewar." The fact is, the only Scotch available in late 1945 would be from prewar stocks. Scotch, like all brown spirits, gets its color and mellowness from wood ageing. The first Scotch made after the end of WWII wouldn't hit America for at least three to five years, if not more.

He probably said that to Luca to impress him (and FFC tried to impress us). Another little fact: unlike wine, spirits do not improve in the bottle--only in the cask before bottling. Their higher alcohol content stabilizes the maturing process once they're in glass. So, even if Tatt had offered Luca a drink of Scotch from a bottle that his father broght over in 1910, it'd taste the same in '45 as it did in '10.
