The practice of wine tasting is the sensory testing and evaluation of wine and ancient traditions like wine itself. Wine tasting and how wine tastes to smell wine are based on the physiology of the process, according to Jordan Ross, an oenologist. Mr. Ross will quickly point out that in wine tasting, taste and smell are often confused, and when it comes to the taste of wine, we mean sweet, sour, salty, bitter, and umami – all of which are picked up by the taste receptors on our tongues. You can consider the wine tasting course to taste different kinds of wines like a professional.
- Retro nose smell
When they smell the wine, it spreads through the nose to the wine-tasting olfactory receptors, which are an inch square and located at the top of the nasal cavity. But the smell also comes in an alternative way – an internal chimney called the "retro-nasal duct" that connects the mouth to the nose. When you swallow, your mouth is closed and you have to breathe in through your nose.
- Smell, emotion, and memory are intertwined and affect the wine tasting experience.
The wine taste buds process smells, memories, and emotions in the brain. The primary olfactory cortex receives information about the smell from nerves in the nose and is directly connected to the amygdala, which controls the expression and experience of emotions, and the hippocampus, which controls memory consolidation.
- Why don't we like the taste of the same wine?
In general, people do not like the same food and also do not have the same taste in wine. Could it be that different people feel things differently? Experiments show that people perceive things differently and some of these differences are genetic. This may explain why some of us like certain smells and tastes while others cannot smell them.
