The new company was named Apaltagua to exploit the positive value of the valley's name and at the same time connect to the Chilean origin.

A production plant with a total capacity of 2.5 million liters was built in a short time before the first harvest in 2000. The premier vintage of wines in the three different quality levels was warmly welcomed, later vintages have also received good ratings.
