My Glass….

My glass is half empty,Yet, I have been getting free wine at work.  What gives?
It is too young, I say, tooooo young to be drunk properly,
So, after a few beers, I can escape into the acidity and the harshness of the too young Nebbiolo,
The childlike Barbaresco,
But the Prosecco,
Never too young.

Glass-where?
