Welcome. Hungary is a beautiful place with interesting people, amazing history great wine. We did a two week crossing from Budapest to Kosice, via Igar a few years ago. Hopefully I'll make it again this year, work of course.
The southern route is the way to go, especially via
Villány, for red wines. Going north of Lake Balaton is mostly white wines.
As others have asked, what are you growing/making? Great web link btw.
Of the varieties I have in the ground, most are new plantings.
Currently only making Welschriesling ("Italian Riesling") in any significant amounts from one hundred fifty, 50 year old vines (they came with the first vineyard). The Pinot gris are the oldest new plantings (5 years old this year) and should surpass the Welschriesling this year or next year. What they lack for in age, they should make up for in sheer numbers.
Of course, also have Mulberry trees just hanging heavy with fruit each year, and so I do a bit of fruit wine to keep myself in practice. Even tried dandelion wine this spring. Just out of curiosity how it would go.
