Wine aromas, especially those in Pinot Noir, are very similar to human sex pheromones. An article published by Wine X Magazine details the connection.
They state: “All those smells you get in the pinot noir grape - spices, earth, musk and the slightly feral, barnyard notes - are very similar smells to those associated with the principal male smell, androstenone. Truffles and the sort of oaky smells in so much wine fermented or matured in new oak barrels are similarly androstenone-like.”
Combine these strong subconscious messages with the effect of wine’s alcohol, and all bets are off.
