The wine auction sites LastHammer works on
LastHammer draws a badge under a lot wherever the same wine and vintage sold at auction in the last 24 months, on the fourteen sites below and nowhere else. The badge shows the last hammer price per 750 ml bottle, the house and the date, and the average of the last three sales; a click opens the sales behind it.
Hammer price, not the price with the premium
Every house adds a buyer's premium on top of the hammer price, and most publish their results with the premium already in. A lot that hammered at $1,000 at a 25% house is shown as $1,250; at a 17% house, $1,170. Comparing those numbers across houses compares the premiums as much as the wines. LastHammer removes each house's premium and divides by the bottles in the lot, so every price is the same thing: what the wine itself fetched, per bottle.

Premiums are those the houses published or charged on the sales in our data as of September 2026. A house that publishes its results at hammer needs nothing removed. Lots in other currencies are kept out of the published prices, so every number is US dollars.
Hammer price, buyer's premium, and what a wine really sold for and how to read a wine auction catalogue, two short guides.
What the extension reads on a page
Only the lot titles, with the vintage and bottle size where the page shows them. It never reads your account, your bids or any other site, and it talks only to api.lasthammer.com. The privacy policy says the same in the same words.
Not on the list
Wine shops with an auction arm (Benchmark, Wine Exchange, Leon & Son, K&L's retail pages) get no badges: a shop price is not a hammer price. A house you would like added: [email protected].
