Nuclear Magnetic Resonance spectroscopists have finally crawled down off their crosses and condescended to the application of their technology to something really useful- the study of wine NMR spectra. If you believe the attached article, a restaurant in NJ has purchased an NMR spectrometer for the purpose of determining the quality of wine. Evidently, the contents of a cork-sealed bottle can be examined by proton and 13C NMR.
Jeepers. I wonder if it is hard to get boxed wines to spin inside the magnet? \;-)
One question. Does the rotating frame turn the opposite direction for Australian wines?
Lamentations on Chemistry 
Does the wine arrive in high quality NMR bottles free of paramagnetic impurities that color cheap soda lime glass? Uncle Al would go for EPR, too, or maybe a big Gouy balance. How ’bout the 1 tesla magnetic wine cozy, big budget Hollywood or off the shelf for little people?
Scam in kind used laser light scattering for particle size distribution in red wine. Folks got over it.

I understand there is quote a shortage of Neodymium- even China is a little short of it.
