This was different and interesting.  One of the better Lambrusco's Tasted.  It is a blend of 30% Lambrusco Marani, 30% Lambrusco Salamino, 20% Lambrusco Maestri, 10% Lambrusco Grasparossa, and 10% Ancellotta.  It is made utilizing the Charmat-Martinotti method in which the secondary fermentation takes place in stainless steel tanks. The carbonation occurs from the decomposition of sugar by added yeasts.  The bottle is sealed with a crown cap.  Purple in color with purple foam.  The nose is a bit grapey with some black cherries and a slight sauerkraut note that faded after about 30 minutes of air (reduction?).  Full bodied and fizzy.  The palate is a combination of raspberry and black cherry soda.  A slight sweetness.  Served with a slight chill, it is refreshing with enough acidity to cut the sweetness.  Each glass seemed better than the prior one or perhaps my palate was adjusting.  For around $20, this is not cheap but fairly priced.  It would work well of course, with pizza, but this would work with a wide variety of foods although seafood is a stretch.
