The International Wine Challenge (IWC) is undertaking the most significant restructuring in its 42-year history, launching four regional competitions across the Americas, Asia Pacific, Europe and the United Kingdom as it seeks to bring judging closer to producers while maintaining a single global benchmark. The new structure, announced this week, will see regional competitions held in Argentina, Australia, France and the UK, replacing the traditional model under which wines from around the world were shipped to London for judging.
