This is a 14 minute vid on Nicolas Joly
Around 8 minutes in he discusses swirling wine in a glass.
Clockwise incarnates the wine, counter-clockwise opens it up.
Around 10:50 his son talks about and shows wave shielding window treatments.
He also makes the comment that non biopdynamic wine is a Stalinist wine.
I would hope he would at least use unnatural.
