The novel “Wine-T₁” NMR pulse sequence, which consists in a saturation-inversion recovery scheme to compute proton spin-lattice relaxation values of metabolites in wine. It consist in three main blocks: A) (90^∘−τ) Multipresaturation of intense water-to-ethanol signals with a home-made shaped pulse (see Methods). B) (180^∘−τ_var) an inversion recovery module applied with a variable delay list (vd) going from 10 milliseconds to five seconds that produces all experimental points representing signal attenuation due to the saturation-inversion recovery process of the magnetization. C) (90^∘− acq) Detection of attenuated signal promoted by the spin-lattice relaxation delay, point B.
