The Kalecik Story
Ancient Winemaking Tradition
The Kalecik region of Ankara has been producing exceptional grapes for over 2,000 years. Our vineyards sit on the same soil that once supplied the ancient civilizations of Anatolia with their finest wines.
Today, we honor this heritage by transforming grape pomace—once considered waste—into valuable ingredients that serve modern beauty and wellness industries worldwide.
