I recently tried the Black Chook sparkling shiraz, and I'm hooked! After that success, I decided to keep myself open to other sparkling reds, and ended up getting a bottle of a Trevor Jones(?) sparkling grenache. I don't remember liking the sparkling grenache as much, but keep in mind that I hadn't re-tried either since then and my memory of the experiences might just favor the initial tasting. Could anyone suggest other interesting sparkling reds with specific vintners and perhaps even vintages? Thanks!
