Finding the Optimal Age of Wine

For this project, I attempted to characterize how the perceived quality of wine relates to its age. To do this, I performed analysis on the Cellar Tracker data set of wine reviews. Through exploration of the data set I found that wine does not age consistently. There was a noticeable shift in the trend of review scores as the wines’ age increased. I performed various forms of regression analysis in an attempt to characterize this shift. Most importantly, I tried to determine the point at which this shift takes place, as it could be considered the optimal time to drink the wine (or the point of diminishing returns on quality). I came up with a model to this end and was able to obtain reasonable estimates for this value.
