The River Stones sector of Adrianna is planted in the path of a dried river filled with white stones covered with lime - limestone.  These stones make for optimal drainage and extreme temperatures because the stones absorb the heat and moderate the nights but also function like ice cubes after a very cold night.  Stony soil Malbecs tend to be extremely aromatic, rich and luxurious, just like the River Stones Malbec from Adrianna.
