title: Using low frequency dielectric absorption to screen full intact wine bottles.
abstract: A ν<25 MHz low frequency spectrometer capable of noninvasively and nondestructively screening the dielectric properties of full intact bottles of wine is described, and along with principal component analysis, used to screen rare wine. The sensitivity of this full bottle method to various ionic and molecular wine solutes was established by analyzing standard solutions. Application of the approach to a library of collectible wine and the identification of counterfeit wine are discussed.
