wine is fragile, you should be buying what you want to drink this year, unless you have a good storage facility (basically a basement or a temperature controlled cupboard), some extra money and a little knowledge. If you do have a basement (and are not planning on moving evry couple of years, cause that can ruin wine, too), you can seriously consider buying good new wine by the case and storing it for future drinking. unless you can document your storage facilities, you can't really sell wine that you stored yourself, so don't think of it as a possible source of profit. What can happen is that you can find that your $1000 investment today became 24 $300 bottles of wine, 7-10 years from now. if you have children, you can put away wine for them, which could put them in a position to drink really expensive wine when they are older. but be warned, often the wine can turn, if you move it too much, if the temperature fluctuates too much, if you don't rotate the bottles the right way, or a variety of other influences, can leave you with some very expensive vinigar. this is the type of thing that warrents a trip to the library or amazon, if you want to try it. I have poured literally hundreds of bucks worth of bad wine way, over the years.
