Freisa is a semi-aromatic red grape variety native to the Piemonte and rarely seen outside of it. It has a family resemblance in flavor profile to Ruche' and Brachetto, and also to Nebbiolo, the last of which I think it is a parent of.
In the non-ripasso form of Freisa, one would expect lifted rose and red fruit aromatic character, as well as some noticeable acidity and sometimes also there are grape tannins. The color of the wine can be more purplish in youth than one might expect from the flavor profile. The wines can age tremendously over 10-15 years from the good producers, and I have had life changing wines with age on them from both Vajra and Coppo (the Mondaccione bottling). Regarding the ageability thing, it is kind of like Gamay, as the wines age they lean up a bit and seem to mimic Nebbiolo more, just as Gamay can mimic Pinot Noir with some age involved.
Other producers to consider if you want to get a handle on the grape variety besides those already mentioned would be Cavallotto, and in the much different ripasso of nebbiolo skins style, Bartolo Mascarello. The version of Bartolo Mascarello is perhaps the outlier today, and is extrememly dense and deep, with dark fruit and unabated mineral character. It is not for the faint of heart, nor is it imported.
If you like Freisa I would point you also in the direction of still Brachetto, perhaps by someone like Corregia, or Ruche' by the likes of Crivelli or Luca Ferraris (specifically the Opera Prima bottling). You might also try a Pelaverga.
Supposedly there is a style of making Freisa in which the result is similar to Brachetto d'Acqui, that is to say somewhat sweet and also frizzante, but I have never encountered an example.
Freisa is blended at times. With what other grape variety tends to be related to where you are in the Piemonte. There is an appellation for Freisa and Gringolino blended together that I would like to try someday. So far, I don't think I have had the opportunity.
I would specifically like to thank Joe Salamone for introducing me to some of the benchmark Freisa bottlings.
