thank you for all the suggestions
Thanks for all the wonderful suggestions. As luck would have it, at Cost Plus last night I saw Cristalino (I think it was on sale for $6.97?). Having my first drink of it now -- quite nice, good flavor (not cloying); not quite as bubbly as Freixenet but a damned good drink at this pricepoint. ^^
Thank you all for the suggestions. Salut!
