In the early 1990s, Chile was just emerging into the international world of wine. However, Eduardo Chadwick, who had joined his father in the family wine business, Viña Errázuriz, in 1983, already knew from his extensive travels to the wine regions of the world that Chile's land and climate were particularly suited for producing fine wines and had great potential. And when family friend and vintner Agustín Huneeus asked him to spend some time showing Robert Mondavi and his wife Margrit around the Chilean wine country, he was delighted to have the opportunity.

Robert Mondavi found a kindred spirit in young Eduardo Chadwick, who spent a week showing him around central Chile in 1991. They visited many wineries in the Aconcagua, Maipo, and Colchagua valleys.

Seña needed a vineyard of its own, and Tim Mondavi and Eduardo Chadwick began searching for just the right terroir. Tim was ahead of his time in insisting they seek out a cooler site in order to make a fresher, more elegant wine than was the norm in the mid-1990s. And because they agreed that the use of sustainable practices was a key element from the beginning, they also looked for a site that was relatively self-contained for better environmental protection and to prevent cross-contamination from neighbours involved in conventional agricultural practices.

Today, although the road has begun, there is still much to do and go. Eduardo Chadwick's daughters, María Eugenia, María Magdalena, María José and Alejandra, not only give joy and meaning to the life of Seña's founder because of their family ties, but also because they are venturing into the wonderful world of viticulture.
