As part of an audition for CBC’s Dragons’ Den, Harald Tomesch demonstrated his patented invention: QikVin, a wine preservation system that eliminates air exposure without the need for external pumps or gas cartridges. In the video, Tomesch pours wine into the QikVin bottle and uses a built-in piston to remove air from the container. As he serves multiple glasses, the self-adjusting piston keeps the remaining wine sealed and protected, showcasing the system’s simplicity and effectiveness. This inventive solution reflects Tomesch’s broader passion for blending design, science, and everyday utility.
