Why is new wine to be put in new wineskins and not old?

Mark 2:22 (ESV)

22 And no one puts new wine into old wineskins. If he does, the wine will burst the skins and the wine is destroyed, and so are the skins. But new wine is for fresh wineskins.”

The young wine ferments and the old wineskins cannot withstand this action. New wineskins are sufficiently supple to tolerate the strain of the young wine. In short, new wine is not meant to top up old wineskins!1
