 So, I heard there was a test that literally you put in multiple different pieces of paper, if I understand correctly, in your mouth, and it can give you a very good idea of what kind of preferences you have in wine, what you'll probably not like and what you will like. And it has to do with basically the distribution of sweetness and bitterness, and it's an actual science. Is that true? Yeah. So, what we've released is called being at a taster. So, what the test is, is it's measuring your specific taste sensitivity or your phenotypic expression of these taste receptors. So, what we did was we took the primary components of wine, the tannins, residual sugar, body, alcohol level, acidity, and you measure the specific taste receptors in your mouth, and then on the app, the algorithm curates a wine selection specific for your taste receptors.
