Using low frequency full bottle diamagnetic screening to study collectible wine

A low frequency ν < 30 MHz spectrometer capable of noninvasively and nondestructively screening the diamagnetic properties of full intact bottles of wine is described, and along with principal component analysis, used to compare and contrast sealed bottles of wine. The sensitivity of this approach to various ionic and molecular wine solutes is established by analyzing standard solutions. The successful application of this full bottle method to a library of collectible wine is discussed and suggests that the method can be used to identify counterfeit wine without violating the bottle.
