Shiraz is a cool name, but it's a Red Wine... great for a Red poodle maybe?
Here are some more champagne names...
Alfred Gratien, Billecart-Salmon, Bollinger, Charles Heidsieck,De Venoge, Henriot, Gosset, Jacquesson, Ruinart, Salon, Taittinger, Veuve Clicquot.Krug, Lanson, Laurent-Perrier, Moet et Chadon, Pol Roger, Pommery
Pommery is kinda cute for a female.. Clicquot is really cool too, I just usually steer away from names that you always have to tell people how to pronounce or spell!
What about the name, Journey, I've always loved that for a female dog name... not a champagne I know but pretty, and has the eee sound...
I was also thinking about White Wine names instead of champagne, they're more recognizable to people ... I LOVE
Pinot for a name (pronounced Pee-no), I would just spell it Pino and eliminate people pronouncing the t... I think it's adorable!
Riesling would work too... Sauvignon Blanc, call her Savvy for short?
Anyway, just throwing some ideas your way...I love naming puppies!!
