The grapevines go through different stages during their annual growth cycle, one of them is the “bleeding”

When the temperature surpass 9-10º C and the soil begins to warm, hormones contained in the roots activate the plant metabolism.

The grapevine comes out of its dormancy period and the “bleeding” occurs.  By osmotic forces the water is pushed upwards,  containing a low concentration of organic acids, hormones, minerals  and sugars and it is expelled from the wounds left over from pruning the vine.  This is the beginning, the grapevine awakes and it is renewed from within.

The bleeding stops when the wounds are covered  by rubbery substances caused by bacteria  and dissolved salts that seal them.

The bleeding marks the beginning, the next harvest is on its way
