Answer: LIVES TRUNK
there are several factors that can lead to cracks in the trunk of a very old vine.
It could simply be an excessively long and cold winter season, followed by very hot and dry periods, in which case the plant will now hold cracks, which should not however lead to any effect on the vigor and production of the plant.
It could be a fungal disease, such as loved ones that occur on the olive tree, in this case it is good to check the wood around the cracks: if it changes color or if it becomes soft or spongy, then it is good to intervene, removing all the weathered wood and covering the wound with pruning mastic, with an antifungal inside.
In principle it should not be something of concern, but it depends a lot on what will happen in the coming weeks: clear that if the plant is suffering, if the foliage has spots, if some branches perish, if from the wounds an unpleasant exudate emerges, then it is a disease.
But knowing only that a plant has cracks on the trunk is not enough to make an overall diagnosis.
In any case, I advise you to supervise the development of the plant and to control the cracks, "disinfecting" them with a copper-based product, since, even if the cracks were to originate from the climate, they are now a kind of door to diseases fungal of all kinds; then clean the wood with an antifungal and / or cover the cracks with mastic for pruning.
