Adega Entre os Ríos is a small familly owned vineyard located on the slopes of the Barbanza peninsula, in the Rías Baixas. The orientation of the vineyards towards the south-west, the natural viticulture, the granite and schists soils, and the use of the most modern technologies in the cellar are the key components towards higher quality wines. The vines are primarily albariño that comes from the old plants of the Merced convent, and were selected and recovered more than 35 years ago. In the making of wines, Jose Crusat respects tradition to the maximum, but subjects it to the criticism of the current oenological science.
