Personally, I only water a new vine if it shows physical signs of needing water. That is I let the plants tell me if it needs water or not. Else, I do not add water. That is, I check them twice a day, but I do not over think it. If they have signs of wilt, they get water. Plants are not damaged by the some water stress wilt (as long as you do not let it persist for more than one day) and they always "spring back".
By letting the vines "tough it out" means they will make better deep roots for long term heath. Which is why I also do not drip irrigate or water on top as that may stimulate shallow roots. When a vine needs water, I use a deep probe and inject water into or even below the root zone, so the roots dive deep for soil water. For adult wines, that is where the water will be, so the young vines need to set roots into that zone as soon as possible**.
I also only plant vines in the fall. That lets them settle in during the winter, and easily can tap soil moisture in the spring to build healthy roots, reducing root stress.
**Which of course is also the question to ask: Your area. Because soil type alone is not enough. Local climate also matters. As I live in a temperate climate, with plenty of winter rain and snow and summer rain I do not have to irrigate my adult vines at all. Despite my clay soils, above the vine root zone, getting very dry and turn to concrete between summer rains. But some climates do not have water in the soil to keep vines alive even to a depth of 2 meters which a vines roots can extend (ergo, those areas requires irrigation even for the adult vines). So your water pattern now is dictated by your local climate.
