A bottle of wine goes through many steps before it reaches the glass. Starting from the grape, it is monitored, barrelled, bottled, registered, regulated, stored, moved, and sold. At each stage, people rely on trust instead of checking every detail. This can lead to issues such as counterfeit bottles, lost records, and questions from buyers about the wine’s origin. The main challenge is making wine traceable without adding cost or slowing down the process. Prof. Joshua Ellul and Prof. Gordon Pace at the University of Malta, and their team, are working on this problem.
