Perhaps the most comprehensive app out there, CellarTracker – which has an equally comprehensive website to complement it – is renowned for its huge database of wine reviews. The app connects wine consumers with more than eight million tasting notes, for three million-plus wines, by a community in excess of 600,000 users.
Detailed information on grape varieties, wine regions and food pairing comes from an active community of consumers and professional users (including pro reviewers Antonio Galloni and Allen Meadows) that can help you with almost any recommendation.
