The above text is a little confused. Here is the Wikipedia reference: “In 1920, following the fall of the Austro-Hungarian Empire, a small part of the Tokaj wine region (approx. 1.75 km²) became part of Czechoslovakia due to the Treaty of Trianon, while the rest remained part of Hungary.” I am not sure that the date of 1920 is correct (de facto it was 1918), but I have printed references to two villages, Kistoronya and Sz?l?ske, and 175 hectares of land within the wine region being ceded to Czechoslovakia. There is another reference in Wikipedia to this being only 120 hectares. The adding in 1959 of four villages to the Czechoslovak wine region was nothing to do with the Treaty of Trianon.

“The situation with Slovakia where about 10 per cent of the Tokaji region resides”. This is incorrect. The historical Tokaj wine region consisted of 9,829 hectares of vineyards rated Class I in the cadastre. So the 175 hectares ceded to Slovakia was less than 2% of the total. The current Slovakian wine region of Tokaj is larger because surrounding land was added to it, but these additional vineyards were never part of the historical Tokaj wine region. In any case, the figure of 10% is wrong because the size of the current Slovakian wine region of Tokaj is 998 hectares, while the Hungarian wine region of Tokaj-Hegyalja has 7,000 hectares of classified vineyard. Just do the maths!
