About the Challenge

The International Wine Challenge (IWC) owned by William Reed Business Media is now in its 34th year. The IWC is accepted as the world's finest and most meticulously judged wine competition which assesses every wine blind and judges each for its faithfulness to style, region and vintage. Throughout the rigorous judging processes, each medal-winning wine is tasted on three separate occasions by at least 10 different judges and awards include medals (Trophy, Gold, Silver, Bronze) and Commended and Great Value awards.

An overview of the IWC process

Tranche 1/Tranche 2

The IWC has two separate tastings to accommodate the different production and sales schedules across the industry. Tranche 1 wines will be tasted in November and Tranche 2 wines will be tasted in April, with wines tasted in the context of style, country and region.

There are two medal release dates, with Tranche 1 results announced in December and Tranche 2 in May. Wines that have won a Gold medal in Tranche 1 will be held in temperature-controlled storage until April. They will then be flighted with Gold medal wines from Tranche 2 for the Trophy tasting in April.

Now let's have a look at what happens to your wines after you've entered the Challenge. Please note that the process is the same for both Tranches. 

Wines from the depot are checked, given a unique code, repackaged and sent to the tasting venue in preparation for the judging.

Sorting and Photographing
On arrival wines are unloaded on to shelves in a temperature controlled storage facility. Wines are organised by style then country so that they are easy to locate. At this stage wines are also photographed for our website and App.

Picking and Flighting
Wines are picked from the shelves and put into 'tasting flights' – a group of wines with a similar style and from the same country and region. All flights are then put into blind tasting bags and tagged with their unique identifier to keep their true identity concealed. The wines are now ready for judging.

Round One
Round one of the judging commences. Wines are either marked as 'out', given a Commended award or progress to the next round. The IWC Chairmen then re-taste all 'outs' and 'commended' wines to confirm the mark. If the IWC Chairmen believe the wine is eligible it may be re-entered into round two to give it another chance.

Round Two
Round two of the judging begins. Wines are marked as 'out', given a Commended award or awarded Gold, Silver or Bronze medals. All wines are re-tasted by the IWC Chairmen to verify the results.

Trophy Tasting
Wines awarded Gold medals in both Tranche 1 and Tranche 2 progress to the Trophy round. The results are then combined and Tranche 1 and Tranche 2 wines put into new 'flights' for more blind tasting. Gold and Silver medal-winning wines that fall into the Great Value category are also tasted at this time. Regional and national Trophies and Great Value medals are awarded. All Trophy winning wines are re-tasted by the IWC Chairmen who then decide which wines should be awarded the Champion Trophies.

Once the judging has ceased all bottles, left over wine, packaging and corks all get recycled. In 2014 the IWC recycled 9 cubic metres of Wine and 55 cubic metres of polystyrene was transformed into insulation for houses.
