Hello Brewer
Thanks for the encouraging response and tip re the Poulter book!
When we 1st started looking at buying property in Slovenia it wasn't really with a view to getting into viticulture, however, in the area we are buying (Prekmuje, near the Hungarian & Croatian borders) almost all of the houses we saw had vineyards as it's a real local obsession. If you are interested in buying Slovenia you could look at the Slovenia For Families website (this is just a personal recommendation, I have no business links with them or with anyone else, actually!).
