Brachetto is different from other Northern Italian red wines that may spring readily to mind; it is neither big, nor bold, nor boozy. Instead it is slightly petillant and sweet with a very low alcohol level.
That is to say, it is not a Barolo.
In some ways you might think of lambrusco when drinking it--except that good lambruscos are often not sweet and also can have a higher alcohol level (some lambruscos, it is true, will have low alcohol and sweetness). But brachetto probably has more in common with birbet, another Italian grape that is used to make sweet, low alcohol wines.
This particular wine has slight bit of "vinegariness" beneath the surface and the sweetness. There is a honeyed quality to this wine and a bright berry flavor--think something ripe and sweet. This is definitely a wine to drink as an aperitif or for dessert. Any sort of cake with berries would be a good match. Any pastry with blackberries, elderberries or similar things in it would work well with this brachetto.
If you are a fan of Moscato this is a nice alternative to that that serves basically the same purpose--except it is a red. Pour your "Roscato" down the sink and grab a brachetto.
