Description

General description

4-Ethylphenol (4-EP) is a para-substituted phenolic compound. It is one of the important aroma compounds in red wine. The aroma associated with 4-EP in red wine has been described as ′′horsy′′, ′′leather′′, ′′medicinal′′, ′′smoky′′, ′′barnyard′′, ′′animal′′ and ′′sweaty saddle′′-like. Production of 4-EP from p-coumaric acid in synthetic media utilizing several yeast species associated with wine production has been reported.

Application

• Sorption Behavior of Volatile Phenols at the Oak Wood/Wine Interface in a Model System.: This research explores the interaction between 4-ethylphenol and oak wood in wine aging, contributing to the understanding of volatile phenol adsorption and its impact on wine flavor (Barrera-García et al., 2006).
