Time-Intensity Methodology for Wine Flavor Evaluation

Traditionally, sensory methods such as quantitative descriptive analysis consider the sensory properties like a static phenomenon. However, due to the dynamic nature of wine consumption, sensory dynamic methodologies provide us with more specific information about the evolution of the flavor perception of a wine, also considering the long-lasting perception experienced when the wine is already consumed. In this sense, the Time-Intensity methodology evaluates how the intensity of an attribute varies over time. The purpose of this chapter is to provide the necessary steps to perform a Time-Intensity analysis for wine flavor evaluation, also showing how to train the panel and how data should be collected and processed.
