It was not Rosa Regale, I like that one too and do purchase it locally. This is different in flavor from Rosa Regale and was listed as "Enchanted Rose Sparkling Wine" and was $5.75 a glass it is not a champagne, but a sparkling wine. It had Abbarazi(?) or something like that listed after the name of the wine.
The Tattangers Pink Champagne was $91 in the duty free shop onboard.
