RT Journal Article SR Electronic T1 The effect of Concentration Conditions and Storage Temperatures on Grape Juice Concentrate JF American Journal of Enology and Viticulture JO Am J Enol Vitic.

Ough YR 1965 UL http://www.ajevonline.org/content/16/3/129.abstract AB To produce concentrate of the highest quality obtainable from any given lot of grapes, the degree of heat damage must be minimized during its manufacture. Having accomplished this, the concentrate must be stored at a temperature that provides optimum "storage-life". Storage-life is just about doubled for each decrease of 10°F in storage temperature.
