There comes a time when you need to decide what to do with your wine cellar. It is easy if your child or children are interested. They will be delighted to inherit your bottles. But what if you have no children or they express no interest in your wine?
There are then essentially two options. Option 1 is to at some point sell the cellar to an auction house or retailer who acquires wine cellars. It is a little sad though, if you move from 100 to 0, or say 5, in one foul swoop.
Option 2 is to reduce the cellar while still buying wine. This is how you do it. Say, you consume on average 20 bottles per month. If you are then disciplined enough to buy just one case per month, you reduce your cellar by 100 bottles per year. Instead of buying one case, you may decide to buy 2 6-packs or 3 bottles of four different wines. This still allows you to keep up with a lot of variety if you wish. And you may decide to buy better quality.
In this way, I have reduced my wine cellar from 1500 to 700 bottles in the last eight years. When I get to 200 or 300 bottles, I need to work out how to still have aged wine. Maybe buy at auction from time to time.
