Vines that grow at high altitudes are exposed to more ultraviolet light. This makes the grapes develop with thicker skins, it increases their anthrocyanin concentration and implies higher tannins levels, all of which result in the creation of more colored wines, more softness and less astringency.
The poor soil full of rocks and pebbles that is found on the slopes of the Prades Mountains causes a varied effect on the vines, as each stone reflects the sun in different ways, producing fruit with higher levels of natural acidity when compared with the grapes grown at lower altitudes. Good levels of acidity in the fruit benefits the later production of high quality wine, with intense concentration, body and flavour. These wines are particularly suitable for long aging.
Grapes grown  at altitude have greater sun exposure and have a higher amount of Resveratrol and Procyanidin, the antioxidants found in thicker grape skins. These have antiviral, neuroprotective, anti-aging and anti-inflammatory effects.
The high altitude in CARA NORD gives grapes a high content of polyphenols. Recent research suggests that red wines with higher levels of polyphenols may lower the risk of heart diseases.
