Beautiful, thank you for this Chateau Vin, but I have a problem with single vineyard nebbiolos. I just don't think the terroirs is distinctive enough to justify the premium in price. As opposed to Burgundy where Grand Crus and 1er crus were designated a few hundred years ago, Barolo and Barbaresco only started designating Single Crus about 40-50 years ago, the cynic in me thinks it is just a way to jack up prices.
Now, obviously some terrain is better than other, the top of a hill will have more concentrated wines than the bottom, older vines planted in some areas will of course produce more complex wines than younger vines but for me, Barolo and Barbaresco, even more than Burgundy is about producer and vintage first and foremost.
That said there are exceptions

Santo Stefano di Neive, Sori San Lorenzo, Cascina Francia, Faletto, and a few others, but for wines that will not cost your first born I still would go for the regular wine (the normale in the case of the Produttori)
And please let's go ahead and debate this but for me, and I said this before, I find single vineyard Barolo and Barbaresco to be more of an intellectual exercise, trying find the strengths and flaws in each vineyard. I personally prefer blends which, when properly done, are more enjoyable and are a better reflection of the area and the winemaker as whole.
