There are many cellar management software programs available on the market, which can either be purchased as a CD-ROM or downloaded from the internet. All are based on a spreadsheet format with fields for recording information about your wine, with an explanation of how to complete the fields. Some are linked to vintage charts and tasting notes from well-known critics. You can also buy regular vintage updates and incorporate them into your system. It is a good idea to download a trial example from the internet before buying.
