The eleventh edition of WineOS, taking place on January 16 and 17, 2026, in Osijek, once again confirms the fair’s status as one of the most important wine and gastronomy events in this part of Europe. Alongside its strong exhibition program, WineOS has spent years building its reputation through education, with its masterclass workshops becoming one of the event’s most recognizable and highly regarded features.
This year’s WineOS by Graševina Croatica will feature seven exceptional masterclass workshops over two days. The program has been designed to meet the expectations of wine professionals, hospitality experts, sommeliers, and experienced wine enthusiasts, as well as those looking to deepen their knowledge through structured, expert-led, and inspiring educational experiences.
The masterclass program will be led by two distinguished European sommeliers, Darko Lugarić and Mario Meštrović. Both are respected names in the wine world, renowned for their expertise, experience, and exceptional ability to interpret wine. Their approach combines knowledge, practical experience, and storytelling, transforming each workshop into not only an outstanding tasting session but also an unforgettable wine experience.
The program explores some of the world’s most important and fascinating wine regions and styles, from Champagne, a symbol of elegance and celebration, through the Mediterranean, to the exceptional red wines of Bordeaux. Masterclass participants will also discover the terroir of Herzegovina, tasting indigenous grape varieties and learning how vineyard location and altitude influence wine styles.
Saturday’s program features workshops dedicated to Riesling, one of the world’s most complex and highly regarded white grape varieties, and concludes with a comparative tasting of two iconic wine regions, Burgundy and Piedmont, representing two distinct yet equally passionate approaches to exceptional winemaking.
WineOS masterclass workshops have consistently sold out in advance for years, clearly demonstrating their quality and relevance. They are not merely an addition to the fair; they form its intellectual and educational foundation. Through this program, WineOS continues to establish itself as a leading reference point for wine education in Southeastern Europe, bringing together knowledge, experience, and the highest professional standards.
So, if your travels bring you to Osijek this January, there is still time to reserve your place at one of these outstanding educational workshops. You will leave with valuable knowledge and an enriching experience that every true wine enthusiast deserves.
