OK, that was of no help, I know that. But the truth of the matter is there are many factors that affect the price of a wine. Chief among those factors is scarcity: nothing like unbridled demand coupled with a fixed, and hopefully limited, supply to drive a wine’s price into the stratosphere!
Other factors include the prices of comparable wines, competing wines from around the world, as well as a wine’s track record for quality and ageing. Counter-intuitively, one of the factors that contributes to a wine’s high price is the likelihood of that price increasing further in the future. Thus the wine’s ability to improve over time plays a big role in how expensive a wine gets.
