As a low yielding grape, it's not that profitable, and the Di Avellino DOCG (higher quality) wines aren't widely available.
Jancis Robinson indicates that historians speculate Fiano may have been the grape behind the Roman wine Apianum that was produced in the hills above Avellino. A historic provenance indeed, though a recent tasting of Orange Wine has me in no hurry to experience the ancient version.
At £7.25 I wasn't expecting much, but there were hints of complexity, some floral and nutty notes along with what Mr Purple Teeth described as a pleasing red grapefruit note.
The Purple Teeth verdict is buy again.
If you enjoy a crisp and dry white with some minerality, give it a try. Look out for peach and fruit flavours, and some hazelnut if you're lucky. If you're not a Wine Society member, you could try this Fiano I wrote about a while back from Majestic. I wouldn't recommend the one from M&S I wrote about here.
