The challenge, which this year attracted more than 10,000 entries, is regarded as one of the most influential wine competitions in the world.
Seven gold medals awarded to pinot noir wines from New Zealand, sauvignon blanc wines picked up five, syrah four and chardonnay wines three.
Champion Trophy winners will be announced after an awards dinner in London in September.
Wines are not only entered by wine companies but also by distributors and supermarket chains, so it's possible for a wine to be in the competition, without the company that produces it knowing.
Over the past fortnight some 300 judges and associate judges have been tasting and rating wines from all over the world.
