A Journey Rooted in Passion
From family vineyard to sustainable innovation leader
The Family Vineyard Story
Hande's connection to viticulture began in her family vineyard over two decades ago. Growing up surrounded by grape cultivation, she witnessed firsthand the potential of grape pomace - the solid remains of grapes after pressing - that was traditionally discarded as waste. This early exposure to both the beauty and the waste of wine production planted the seeds for what would become Posamas.

Innovation Vision
The vision for Posamas emerged from Hande's unique combination of technical expertise and deep understanding of viticulture.
