The news:
Before this, the vodka is stored for three years in cognac barrels, and the bottles in which it is locked are covered with 24-carat gold.

The discussion:
Why should vodka last for 3 years?
yyy: so that it absorbs the strength of the material from which the barrels are made.
Why does vodka have a tree?
Zzz: to get drunk in the board.
