Over the past year and a half I've watched this application grow better and better with each release. I use it to manage my 500-bottle collection, and it's the best wine manager I've found for the Macintosh.

The amount of data that can be kept on a bottle is staggering. I mostly use the basic information (type, region, year, best-drinking dates) and ratings from my favorite wine reviewers. The built in cellar reports do everything I need them to do, but they're also customizable via templates.

One nice feature that the author added is that winery & wine supplier information is stored in the Mac Address Book, so that they're available through that application as well.
