Hi Jose. Well this is a nice little obscure grape which seems to crop up in lots of places. My notes tell me it may have been used on Madeira, is grown in the Languedoc and north as far as Muscadet as well as Corsica and Sicily. It also crops up in Italy and the Douro and Rhone valleys!
On Corsica it has a DOC Vermentino de Gallura but I definately haven’t tried it!
Jancis Robinson MW suggests it may be a Malvasia and goes on to suggest ’those who have tasted the varietal Vermentino know that the wines are big and ripe-fruit flavoured with genuine interest - rather like the most serious white wines of the rhone’.
It may well therefore be a small constituent of a number of wines in all the above areas without being specifically identified.
I hope this is helpful
I had a further look through the books last night, I like a challenge, and I was reminded that in the Languedoc vermentino is known as bourbolenc. It is a major constituent ( at least 50% )of Minervois AOC dry white for example. I have tried these wines when travelling there and remember a complex spicy full wine. Well worth the effort of a deviation if travelling that way.
