A nossa metodologia

Our customers are wineries with a great innovative spirit, wineries with a vision of the future, capable of accumulating knowledge and new experiences; and sensitive to their workers and environment.

All consultancies are established after a preliminary analysis of the winery, a study of the problem and the definition of the specific objectives and needs of the winery.

Consultancy plans have a start and end date for the project.

Our consultants have a working methodology transferred to the customer through regular reports. The consultant establishes a dynamic that helps the winery establish new methodologies and processes.

Our working system allows us to coordinate the different strategic departments of the winery: general management, viticulture department, enological department, and commercial department, involving them all in the same project and with the same common objectives.

In order to achieve the objectives of these consultancies, the participation of the manager, production, commercial, technical and financial directors is necessary in most projects.
