Abstract

Stem contact maceration is a technique used in red winemaking for wines poor of phenolic constituents (tannins) in order to improve organoleptic characteristics and ensure color stability over time. This article investigates how the presence of different amounts of de-stemmed bunches affects stilbenoids, known for their nutraceutical properties and biogenic amines (BAs), known for their adverse physiological and toxicological effects, at racking and after 24 months of storage in Primitivo wine. Stilbenes found in Primitivo were not influenced by the stems during maceration/fermentation. The ageing period resulted in isomerization phenomena of trans forms of piceid and resveratrol to the corresponding cis forms. The presence of stems during the winemaking did not induced the production or enhanced BAs content. Therefore, this enological practice does not represent a limit in terms of food safety and product quality.

Practical applications

Red wines poor in proanthocyanidins are subjected to color loss and decrease of organoleptic properties over time. Stem contact maceration is a technique used in red winemaking in order to enforce structure and stabilize color over time. Since food safety and product quality are of paramount importance, this study for the first time examines the presence of dangerous biogenic amines (BAs) and potent antioxidant stilbenoids throughout the production and aging of red wines produced with this technique. Results may benefit the winemaking industry and researchers who are striving to improve the processing and marketing of red wine.
