The Discovery Tasting, on May 2 at London's Barbican, will include medal winners, trophy winners and some champion wines. Last year, wines from 25 countries, including 38 gold medal winners, were on show.
Trade buyers will have a "rare opportunity to taste at their leisure" and find new wines to add to their portfolios.
Wines will be laid out by country, region, grape variety and style. The free tasting is open to buyers, agents, wholesalers, somme liers and journalists. E-mail firstname.lastname@example.org, or check www.internationalwinechallenge.com.
