Cross-Modal association is the pattern of how our brains naturally integrate and simultaneously utilize sensory inputs from two or more of our human senses. The Wine Aroma Matrix is based on the cross-modal association of our vision and olfactory senses. For example, when you first tasted cinnamon toast not only did you learn the aroma of cinnamon spice but you also learned the ‘brown color’ of cinnamon spice. The cross-modal association of vision and olfactory senses naturally enhances our ability to recall and identify specific wine aromas.
