We have one of the world's most comprehensive databases for pricing fine wine. For over ten years, we have manually entered every auction sale price into our system and tracked sale prices on our ecommerce platform. We also generate live pricing data from Wine-Searcher. All of this and more feeds into our proprietary pricing algorithm, and the result is our Value price. This is the price used to calculate your Cellar Valuation and to determine many of your personalized recommendations.
