Key Takeaways
Johannes explains that master sommeliers train their brain’s sense of smell just as many people train physically when they go to the gym. The key is to make it challenging. What we can train most about smell is its connection with language. It’s important to talk about the smells we detect with each other. It's not enough just to have odors go by. You have to actively try to identify them.
Smelling is difficult for humans Johannes observes. We can oversee a visual scenery very quickly. With smelling, we don't have these abilities. When we smell something in our environment, it is much more work for us to identify the particular odors, and we have to concentrate. We don't do that a lot. So you need to have the mental spare time to focus.
Johannes says that retronasal olfaction is not only when you swallow wine, it's also when you have it in your mouth. When sommeliers swish the wine around their mouths, the molecules heat up and get pushed up into the nasal cavity, which is also part of the retro nasal component. You can test this by just pinching your nose. You won't smell because it's blocked in the front, the air cannot enter. Then as soon as you release the nose, then you will have this additional smell dimension. Retronasal olfaction is really the key player when it comes to smell and flavor perception.
