Help! Trying to find a comparable wine.

[Lucky13csa]

I have a friend and his wife who were very impressed with an Italian sparkling wine Rosa Regale. They are having fun trying to find a comparable wine. Some say that there isn't anything close to it. Hogwash, I say....LOL. Can anybody make any suggestions as to what might come close? Can anybody tell me something about that wine? Like history, vineyard, or process? Anything would be appreciated. Give me some ideas and let them be the judge of whether it's close or not after all, it's their tastebuds that tasted that Rosa Regale and everybody tastes some things differently. Besides it's fun trying out different wines. Well, thanks in advance.
