More about Ca di Rajo Treviso Extra Dry Prosecco Ca di Rajo is a nearly century-old producer who has been in the forefront of the Valdobiaddine DOCG development, winning awards in blind tasting panels including Decanter. The winery still farms a selection of their vines in an ancient, spectacular version of a pergola called Bellussera, which from the top looks like a big diamond grid. Ca di Rajo's diamond-shape label is an homage to this Bellussera tradition and a symbol of their quest to make the best Proseccos available. When it comes to QPR, their Treviso DOC Proseccos overdeliver. Both are made in an extended Charmant (tank) method to produce a creamy rounded mousse and bright floral aromatics.
