Scientific work in Tokaj

Antal Kneip, Lead Researcher of Viticulture

Tokaj Research Institute FOR VITICULTURE AND OENOLOGY

​ The rapidly changing natural and economical environment poses multiple challenges to our current grape-producers and winemakers – global warming and the quarantine caused by Covid-19 and its drastic changes in everyday life represent such challenges. Located in Tarcal, the Tokaj Wine Region’s Research Institute for Viticulture and Oenology handles several grapegrowing region’s research while also exclusively dealing with Tokaj’s wine related topics as well. In the following article, I’ll briefly describe the Institute’s activities and elaborate on more of them in the coming few months.

​The Tokaj Wine Region is home to a unique structure of varieties. Out of its six allowed the most dominant is Furmint, which – most likely originating from the region itself – is the most common plantation in Tokaj-Hegyalja. The multifarious Furmint’s „clones” – artifically propagated types – require constant preservation and research; the same can be said about Hárslevelű, a similar ’hungarikum’. Along with other older, hungarian grape varieties, the above two are preserved in a single hectare Variety Collection on the Szarvas-vineyard, located in Tarcal and available to analysation. In order to keep up the spectrum of variety, my colleagues located close to five hundred old, valuable vines across the Tokaj Region. These will eventually be reproduced to grow the collection – after years of research, of course.
Our plant protection expert utilises an automated meteorological station to help warn us against the dangers of insects and infections which could harm our vineyards; along the „traditional” illnesses, including powdery mildew and other types of mildew, each year presents new issues to our grapes, like black rot or even invasive ladybugs. Protection against these is one of our most important tasks. However, our region has a special connection to the so-called gray rot, since in the correct conditions, this fungus, called Botrytis cinerea can produce noble rot – which means the appearance of precious aszú.
The production of healthy and delicious grapes begins from the ground up and the original roots of our desired species – the subject – are also highly important. In order to protect against phylloxera, our European species are planted onto North-American species, which are located just below the ground under the vines. Certain rootstocks ensure protection against dryness, while others can speed up or slow down the process of ripening. Choosing the ideal rootstock variety is as important as the soil’s nutrient contents, the well-being of the soil-microbes’ community and preserving the structure of the ground, which is tended to by our colleague expertising in soil science and nutrient management.
We’re currently making our first moves in two vital areas: the highly resistant grapetypes’ newest generation is appearing today in several vineyards. In about 20-30 years, they will become a topic of much discussion and study regarding the evaluation of them as „Tokaji” wine and cross-breeding them with other types and species. Geographic information systems and automatisation represent the precision-based area of the winemaking field, although these systems are still not as widespread as the large-scale production of plants. Despite this, the sight of drones and harvesting machines might be an everyday sight in Tokaj’s future vineyards.

​Our new microbiology and wine lab serves the Tokaj Region’s winemakers with high quality instruments and tools, since every step in the process of winemaking requires the appropriate analytical studies, which are required high quality production. These studies include the research of different strains of yeast found in Tokaj’s cellars, the different treatments’ effects on the nature of wines and older grapes’ microvinification; growing these in extremely small amounts. Ecological grapegrowing and organic winemaking – producing organic grapes and wine – requires the thorough and precise study of all of the above fields and demands a sort of „system theory” from the winemaker. We consider not only the gathering of information on these topics to be important, but also passing them down to the next generation and providing them with experience and knowledge of the past.
