Tempted by the world of auctions but not sure where to start? Intimidated by the specialist language used, or unfamiliar with how bidding works? We’re here to explain what happens behind the scenes and how to navigate this niche but exciting way of buying fine wine!

How do iDealwine’s auctions work?

As an auctioneer, we differ slightly from others in the industry; even though our sales follow the same model as a traditional, in-person auction house, they are all organised electronically via our website. We should stress, though, that every bottle up for auction is subject to the same assessment, verification, authenticity checks, and payment security as a more classic auctioneer. Indeed, we have a whole team of experts dedicated to this very task, and they make up around a quarter of our in-house workforce.

But where do we get these fine wines from in the first place? Before appearing on our website, the bottles belong to wine enthusiasts and collectors from France and other European countries. Anybody who wishes to sell their wine with us gets in touch with our selling team, who estimate how much the wine is worth and how much it is likely to auction for.

If the seller/consignor is happy with the estimate given, they send their bottles to our warehouse in Colombes (just outside central Paris), where the wine is assessed and verified. If they’re selling a large quantity of wine, our Logistics team can even go and collect the bottles directly from their cellar! In either case, the wine is appraised by us (we check the cork, level, label, colour, etc.), then kept in an adapted warehouse until the closure of the sale.

At iDealwine, an auction generally lasts ten days. This is the window during which bids can be placed by interested buyers. When a collector wishes to sell a large portion of their collection of all of it, the bottles can be put up for auction as “Private Collection” or if there are not enough bottles to make up a full auction, they can be added to other bottles we have going up for auction at the same time to form a “Special Catalogue”.

Most of the wines on our site will have a starting bid (also known as a reserve price), which is the lowest bid you can place on the bottle. You can find this information on the right-hand side of the product page, along with the amount of time remaining and the number of bids already placed:

Other bottles, however, have a starting bid of just €1, giving you more freedom to bid however you see fit. You can filter these bottles using the menus on the left-hand side by Advanced search > Auction status > Without reserve price.

You must already be fully registered with an iDealwine account before you can place any bids. This includes filling in your chosen payment details. Once you have placed a bid, it cannot be revoked! And if you are outbid by another client, we’ll let you know by email so you can decide if you’d like to place another bid.

There are useful functionalities on the site, such as setting your maximum bid on a bottle. This means that the system will automatically increase your bid if it is overtaken, without you having to log in and do it manually each time. You can also choose to track a lot, which means we’ll send you an email half an hour before it closes in case you’d like to place a last-minute bid!

Lot page overview on iDealwine

You can bid up until the very last second, which is thrilling if two or more people have their heart set on a particular bottle! Once the auction is closed, we’ll send you an email summarising the results of the sale and detailing any bottles you’ve won!

Overtime bidding

Sometimes a lot has a lot of interest with wine enthusiasts placing bids right up to the final seconds of the auction. To allow people to have more time to place counter bids, we have added overtime bidding to our website. This is a system whereby the auction end time is automatically extended by 3 minutes when a bidder places a bid in the final 3 minutes of an auction (the time and date of closing are listed in the “Our Auctions” menu).

If another bidder places a bid in the 30 seconds before the new closing time, the catalogue is automatically extended by 30 seconds. This system of extending the auction closing time by 30 seconds can be repeated 9 times, meaning that the maximum time auctions can be extended by cannot exceed 7 minutes and 30 seconds.

Auctions: A glossary of iDealwine terms

Alert: An alert you can place on any bottle that you are looking for in our auctions. You can manage your alerts from the “Alerts / Watch” tab on the My account menu.

Auction report: The monthly reports published by iDealwine detailing all recent auction outcomes and an analysis of the results.

Bidder: The client placing a bid on a lot.

Bidding increment: The minimum amount needed to make a higher bid. For example, if a lot is priced at less than €50, the minimum bidding increment is of €3; if the bottle is priced at between €50 and €100, the minimum bidding increment is of €5. The bidding increments are preset:

Catalogue: A document summarising all the lots featured in a given auction, including their provenance, the amount of wine in the bottle, the price estimate, and the reserve price.

Commission: The successful bidder must add the cost of the buyer’s fee to the hammer price of their purchase. At iDealwine, this is 25.2% including VAT (as of 1 March 2023).

Estimate: How much a bottle of wine is worth, according to our sellers’ team. They base their decision on a comprehensive database of market data and previous auction results.

Hammer price: The highest bid placed on a lot by the time the auction closes. This phrase comes from the idea of the hammer used by an auctioneer to confirm the sale of a lot.

Licensed auctioneer: Even with an entirely digitised platform, iDealwine has a licensed auctioneer! This is a civil servant outside the company who ensures the smooth running and regularity of our auctions.

Lot: The bottle or set of bottles in question. It can be made up of one bottle or several, and these can be bid on by clients.

Maximum Bid window on the iDealwine website

Maximum bid: To increase your chances of securing the lot you are interested in, and to avoid the risk of going over your budget, you can set a maximum bid on your account. This maximum bid price is the price you are willing to pay to obtain the lot (not visible to other bidders) which will only be reached if others bid against you. Your bid will be increased automatically until the maximum bid is reached.
In order to set a maximum bid, click on the “Maximum button” button below the “current bid”Place bid” button. This will open a new window which allows you to choose your desired maximum bid by clinking on the + and – buttons. Then press confirm, but don’t worry, you will not have bid this amount straight away. Your maximum bid will only be reached if there is competition for the lot.

Reserve price/starting price: The initial price that can serve as a starting bid; it is usually set below the value of our lower price estimate.

Successful bidder: The client who has placed the highest bid at closure and who has thus ‘won’ the lot.
