MISSION IS TO TRANSFORM

"Twenty years ago, meaningful steps were taken to revive Kalecik Karası — a treasured local grape variety that was on the verge of disappearing from its homeland.

In the vineyard, I got synchronized with the rhythm of the earth, tuned with patiently growing grapes, and embraced the value of hard work.

After having years of experience in the technology sector, this time I listened to the call of the earth. It originated from a vineyard again — but now to create a transformation in harmony with nature."
