i think this core thesis might be inherently flawed. It’s overwhelmingly not subjective through the lens of “what do the most knowledgeable and experienced drinkers expect from this wine at peak and when?”
For example, if you’re serious about Burgundy, then you’ll either know or defer to the most knowledgeable people that have experience with Burgundy and you’ll not drink most of your wines at age 4. Though some may choose to, that’s not the goal of this exercise, and isn’t useful data.
I think where CT can provide real value here is notes-based sentiment analysis on an individual wine and then perhaps expand that more generally to a region, vintage, producer, etc., to eventually say something like “volnay from ripe vintages peaks around 13 years from the vintage.” That’s a very actionable statement.
Consumption data from CT, from this POV, is a lagging indicator which isn’t what you’re after. To say nothing of the very reasonable argument that public consumption data will actually drive more consumption by other CT users.
The consumption curve for every wine will have the same shape because reasons, but the slopes will differ; to what extent is the goal here.
