Three very different styles of natural sparklers that prove that it's not all just Pet-Nat. But, of course, we had to include a Pet-Nat for you: Tour des Gendres Petillant Nature, a fresh, grassy, zippy wine that drinks more like a funky dry soda than a Champagne. On the other side of that coin, the Tissot Cremant du Jura Rosé, from a Jura producer that we believe gives Champagne a run for its money. Finally, a funked-out, savory sparkling rosato with a fresh red-berry edge, the Corte Pagliare Verdieri "Ven Crud" is Lambrusco in every way but the region in which it is produced.
