Shows the highest and lowest price a wine has traded for since being listed on BordeauXchange. The arrow/green bar represents where the last traded price sits on that range.

The difference between your price and the opposing bid or offer price.

Example:
You have placed an offer to sell for £1,000 and the highest bid is £800, the difference is 20%.

The percentage change from the previous trade.

Order book is a real-time, electronic list of buy and sell orders, used to match buyers and sellers. It consists of bids (highest prices buyers will pay) and offers/asks (lowest prices sellers will accept).

Each dot represents a vintage of this wine. Its horizontal position shows the critic score; its vertical position shows the market price per bottle.

The green dashed line is the fair value line — the price you would expect a wine to fetch at each score level, based on how this producer's other vintages are priced.

Above the line = priced higher than the score alone would suggest (relatively expensive).
Below the line = priced lower than the score would suggest — a potential value opportunity.

The R-squared figure shows how strongly critic scores predict prices for this producer. Closer to 1.0 means scores are a reliable guide to value; closer to 0 means other factors — rarity, age, availability — are driving prices more than the score.

This chart shows how much each vintage is priced above or below its fair value — the price the log-linear regression model predicts based on its critic score relative to other vintages of the same wine.

Green bars = priced below fair value (potentially underpriced relative to its score).
Red bars = priced above fair value (commanding a premium over what the score alone would suggest).

A bar near zero means the market is pricing this vintage very close to where the model expects it to sit.

Each line shows how the price of a single vintage has changed over time. Because vintages have very different starting prices, all lines are rebased to 0% at the start of the selected time window — so you are comparing performance, not price level.

A line rising above 0% means that vintage has appreciated in the selected period; a line falling below 0% means it has lost value.

Use the range buttons to change the time window. Use the All Vintages dropdown to show or hide individual vintages, or quickly select the last 5 or 10 vintages.

Each dot represents a vintage of this wine. Its horizontal position shows how old the wine is; its vertical position shows how its price has changed over the selected time window.

The dashed trend line shows whether age correlates with recent performance — a rising line means older vintages have appreciated more over the period; a flat or negative line means age is not driving recent returns.

Use the range buttons to change the time window and the £ toggle to switch between percentage and absolute price change. The R² figure shows how strongly age explains the variation in returns for the selected period.

This chart shows how much each vintage is priced above or below its age-based fair value — the price the linear regression model predicts based solely on how old the wine is.

Green bars = priced below what their age would suggest (potentially underpriced relative to their age).
Red bars = priced above what their age alone would suggest (commanding a premium over age-predicted value).

Compare this with the Score vs Price Fair Value chart to see whether mispricings are better explained by score or by age.

The blue line tracks the average performance of all vintages of this producer combined — each vintage is treated equally so the index reflects the producer as a whole rather than being dominated by the most expensive bottles.

The orange line shows this specific wine's market price performance over the same period. When the orange line is above the blue line, this vintage is outperforming the rest of the producer's range; when it is below, the broader range is doing better.

Both series reset to 100 at the start of the selected time window, so you are comparing relative performance, not price level. Use the range buttons to zoom in on different periods.

This chart shows the month-on-month percentage price change for both the market price (blue) and the average traded price (orange).

Each bar represents how much the price moved compared to the previous month — a positive bar means prices rose, a negative bar means they fell. Months with no trades will have no orange bar.

Use the range buttons to zoom into a specific period.

This chart overlays four data series to give a complete picture of trading activity over time.

The orange line shows the market price each month. The blue line shows the average price at which trades actually occurred — months with no trades carry forward the last known traded price. The candlesticks appear only in months with actual trades — the wick shows the full high/low range, and the body shows the open (first trade) to close (last trade). A green body means the last trade of the month was higher than the first; red means lower. The light blue columns show the number of trades in each month (right axis).

Hover over any point to see the market price, average trade price, the high/low range, open and close prices, and the trade count with total £ volume. Use the range buttons to zoom into a specific period.

Each bar shows the average percentage by which actual trades were above or below the market price that month.

Green bars mean trades executed above the market price — buyers were willing to pay up, signalling strong demand.
Red bars mean trades executed below market price — sellers accepted less, signalling weak demand or urgency to sell.

A persistent discount may suggest the published market price is overstated relative to what buyers will actually pay.
