title: Mass-spectrometric study on<sup>13</sup>C/<sup>12</sup>C carbon and<sup>18</sup>O/<sup>16</sup>O oxygen stable isotopes distributions in grapes and wines from the Black Sea regions
abstract: The present study continues the 2015–2016 research project on biological characteristics of stable isotopes fractionation in grapes taking into account the agro-climatic growth conditions of this representative of the C3-pathway of photosynthesis group of plants in different geographical Black Sea regions. The first parts of the project were presented at the 39th and 40th Congresses of OIV in Bento Gonçalves (Brazil) and Sofia (Bulgaria). The scientific data on compositions of 13 C/ 12 C carbon
