With this type of case, how can one know (or at least justify the assumption) that reinvestment of the proceeds should not be considered? It seems like it would be a good opportunity to grow the cellar and increase long-term revenue.
It also looks like the proposed solution reduces the number of investment-grade bottles by 192 at the end of year 5 when evaluating the cellar size, but when looking at revenue generated, only 120 bottles are sold at the end of year 5.
