A study has been completed to look at the ratio of stable isotopes of  δ18O, (D/H)I, (D/H)II, δ13C, δ15N and 87Sr/86Sr moving from the soil, through the cultivation of grapes and their preparation at different stages into wine.  The isotopic ratio of 87Sr/86Sr does not vary significantly from grape to wine, and δ15N has been proposed as further isotopic marker for the geographical characterisation of grape products.
