IMO if you go looking for Barolo or Barbaresco, then the Northern Piemonte wines will disappoint, just like seeking Burgundy in the new world.
They are subtly different, leaner and often a little lighter, yet often with proper tannin and acidity - which can be more appetising to me with food, especially vs. the darker/richer Barolos. On top of that, many of the appellations allow/dictate a blend, including Vespolina, Croatina & Bonarda along with Nebbiolo, whereas (barring the odd unsubstantiated allegation) Barolo and Barbaresco is 100% Nebbiolo by (wine) law.
For me they are worthy in their own way, but for those absolutely set on B&B then there isn’t going to be as much to appeal up there.
I am sitting on some 2006s from Antoniolo. Anyone have a read on how those are doing these days? Think it has been at least 3 years since I opened one.
