362 that I could remember by looking at the chart but a lot of them are dupes and some aren’t even grapes, so it’s actually a bit less I guess.
But here are four more that aren’t in that CT database - Kéknyelű, Ezerjó, Zéta, Kövidinka.
BTW, I was surprised to see Turán, aka Agria, which is even more obscure than the ones I listed. It’s a red-fleshed grape with dark red juice that was often used to darken lighter colored grapes. I had an aszú wine from it, which is completely off the charts.
Anyhow, if anyone is interested, here’s some info on the grapes I listed.
Kéknyelű was once a pretty popular grape that reputedly made some of Hungary’s greatest wines. But it’s hard to grow and today you mostly find it in the western region near Austria.
Ezerjó is mostly found in Pannonhalma but some people have even made aszú wine from it.
Zéta is a cross of Bouvier and Furmint. Until just recently, it was called Oremus. However, when Vega Sicilia bought some property in Tokaj, they took that name for their winery. It would be a little like going to Bordeaux and starting a winery called Chateau Merlot. Actually maybe not, since the grape isn’t really that old, but they changed the name. It’s useful because it ripens fairly early and is easily affected by botrytis, but as far as I know, just like the Muscat in Tokaj or Petit Verdot in Bordeaux, it is usually just a very minor percentage of anyone’s blend.
There isn’t a lot of it but it is one of the earliest ripening grapes in Tokaj so can be useful. I don’t know that anyone releases a commercial aszú from it.
Kövidinka is a high-yielding grape so the communists loved it and it’s planted in the central plain region, where farming is easy but quality grape growing isn’t. Partly because of that, some people today don’t like the grape but a few are trying to make serious wine from it. We’ll have to see.
