The joint research between the Hochschule Geisenheim University and Taras Shevchenko National University of Kyiv (Ukraine) is a successful example of such interdisciplinary cooperation in the fields of wine sciences and chemistry. The teamwork of the German scientific group (Dr. Andrii Tarasov, Prof. Dr. Doris Rauhut, Prof. Dr. Rainer Jung) with Ukrainian colleagues (Dr. Alexey Dobrydnev, Prof. Dr. Yulian Volovenko) started in 2016 from a project devoted to the synthesis and study of 1,1,6trimethyl-1,2-dihydronaphthalene (TDN). This interesting substance gives the controversial kerosene aroma to many Riesling wines. The first visits of Dr. Alexey Dobrydnev to Geisenheim University were supported by the Gesellschaft zur Förderung der Hochschule Geisenheim (GFHG) foundation, which allowed establishing a good basis for the teamwork. Later this led to the joint scientific publications [1- 3] and applications for further research projects in subsequent years. Among them are synthesis and study of Vitispirane, precursors of grape varietal thiols and other wine components. These investigations received support from the DAAD Leonhard-Euler-Program in 2017-2018 and 20192020. Currently we are continuing to work together on the deuterated wine aroma compounds in order to improve the accuracy of wine analysis.
