TY - JOUR T1 - Effects of Acetaldehyde and Tannins on the Color and Chemical Age of Red Muscadine (<em>Vitis rotundifolia</em>) Wine JF - American Journal of Enology and Viticulture JO - Am J Enol Vitic.

Morris Y1 - 1986/01/01 UR - http://www.ajevonline.org/content/37/2/163.abstract N2 - A red muscadine wine treated with 300 or 600 mg/L acetaldehyde had less browning, greater color intensity, and greater chemical age (levels of anthocyanin-tannin polymerization) than an untreated wine. Tannic acid had no major effect on browning or chemical age, but increased color intensity as compared to the control. A commercial "tannin" increased browning slightly, but did not affect color intensity or chemical age. ER -
