Cellartracker works together with many professional reviewers and thus integrate reviews from 23 publicators of wine tasting and reviews.
All the above mentioned is really just a product of what the site originally intended to be, a cellar inventory tool to help you keep track of your wines, when to drink them and to keep track of the value if you are trading.
They have lately extended with apps for iPhone, iPad and have scaled versions of the site for mobile phones.
The site is free to use and almost all features are available to the nonpaying user.
If you decide to pay an annual, from 36$, you can get access to a diserable automatic cellar valuation tool that values your cellar inventory based on auction and community pricing data. You also get access to more professional reviews and there is no longer advertising on the page.
