You make an excellent point.

A wine tasting portion is a sip, that you slurp up and then spit out. No-one (I imagine) thinks of that portion as a real serving size!

I never spit out when tasting wine, that seems pointless to me :) Then again, I'm not a professional or even in any manner advanced taster, I just do it for fun.

Why would you do that, I never even heard of this before.
