Overview
Wine Sell-Through & Liquidity Index (WSLI): wine market data
The Wine Sell-Through & Liquidity Index (WSLI) measures how liquid the fine wine market is, the sell-through rate and how hammer prices land against estimates, rather than price level alone. Liquidity is a factor academic wine economists identify as central to wine as an illiquid alternative asset, and one that price-only indices ignore.
The index is built on ALT/FNDATA's fine wine sales data (over 940,000 sold and 120,000 unsold lots across 290+ auction houses since 1998, with 890,000+ lots carrying both a hammer price and pre-sale estimates), letting it compute sell-through and hammer-to-estimate ratios by segment. Values come in JSON, CSV and SQL formats and update daily.
What you can do with this data
- Liquidity assessment: measure sell-through rate (sold versus offered) across the fine wine market.
- Demand signals: track how hammer prices land against pre-sale estimates over time.
- Risk and timing: gauge tradability before buying or consigning, an input academic research flags as central to wine as an illiquid asset.
- Market health: monitor sell-through and estimate accuracy by region, producer and vintage.
