In general, I do not take much notice when people describe a vintage as great or poor. Hot or cool, yes, because this can be objectively verified. But in terms of quality, there is so much variation that you can find great wines in so called poor vintages, and poor wines in great vintages. The odds are perhaps against it, but I prefer to look at the individual wine.
2012 was regarded as a pretty good vintage in Piedmont, although dwarfed by 2010 and 2013. So when I opened the 2012 E. Pira Chiara Boschis Via Nuova I was pretty confident this should be a good wine at a good time to drink. The Via Nuova is a blended Barolo. The number of vineyards varies between vintages. In 2012, it is a blend of six vineyards, two each from Barolo, Monforte, and Serralunga.
