I don't understand anything about wines and my tastes are as plebian as they get. My buying process is very simple. The price should be "competitive", the bottle should have some aesthetic appeal that separates it from the crowd on the shelf. The label should be interesting or quirky. Since I don't know wines it should not be a brand I am familiar with.
That is a pretty wide net and more often than not the results are good. I have a few friends who "get" wine and over the years they have attempted to educate me but I am not a willing or able student. I love and work with data for a living - unlike wine, I do "get" data. So it was fun to read how this wine model was built and to arrive at a pretty obvious conclusion that alcohol content being the most important variable by far. Would make sense to most people
Alcohol appears to have the biggest impact on Quality, followed by Volatile Acidity and the amount of sulphates in the wine.
Reminds me a great deal of conversations I have had with customers over the years. A big name strategy consultant firm was hired to lay out their business transformation roadmap. The output is super-secret and only a select few have read the report and none of them are willing to share. So some not so fancy consultants show up, take stock of their data and propose a recommendation identical to what they paid millions for. This second opinion is usually free because the lower-tier firm wants to earn the business. As if that were not enough, just about everyone in the company with an operations or delivery role could have come up with the right answer without any help from any consultant. That is the equivalent of alcohol being the most significant quality indicator of wine.
