All base spirits of the company are imported from the French "EAU-DE-VIE GROUP," located in Charente-Maritime, the core producing region of Cognac. It is one of the oldest château systems in the area, with nearly 500 years of winemaking heritage. Its raw materials use premium white grape varieties such as Ugni Blanc, grown in calcareous clay soils and a mild maritime climate, forming a high-acidity, pure, and distillation-friendly base structure that provides an elegant and stable flavor foundation for Cognac.

This partnership system ensures:
- DIRECT SOURCING OF BASE SPIRITS FROM THE ORIGIN
- AOC REGIONAL QUALITY ENDORSEMENT
- TRACEABLE DISTILLATION AND AGING SYSTEM
- LONG-TERM STABLE SUPPLY CAPACITY
