Liv-ex data is based on the activity of over 400 fine wine merchants based in 41 countries worldwide. Their activity accounts for an estimated 90% of fine wine turnover globally. Trades, price updates, bids and offers are standardised, verified and published as tens of millions of historic lines, with thousands of daily updates of reliable, independent and trusted data.
This makes it the only source of data based on real merchant transactions, rather than advertised prices which can be inaccurate and out of date. And this is why it’s relied upon by the world’s biggest fine wine players and quoted by media outlets including Reuters and Bloomberg.
