Thanks for the comments. I’ve never considered that part of the equation. I always guessed that winemakers only sold a certain percentage (50% at most) of any wine on futures. That way they wouldn’t get caught in the bind you mentioned.
A requested to the wine drinking world (which I assume will be ignored). When Mary, or other winemakers, do early releases and tell the buyers that the wine needs X amount of cellar time before being drank, Don’t post TNs on the wine before then!
I’m sure that will bring outrage and fury!
