I am fully aware this question is not suitable for AC Aeroplan here, but since I am 90% flying AC and only want to learn from fellow AC flyers, just post it here (I will not get mad if someone removes this question to another area, and I may never find it).

Can any wine expert teach me any knowledge of the best Italian red sparkling wines? I am familiar with most champagne/white and rose sparklings, but know nothing about the most recognizable red sparkling, such as asti spumante or any shiraz or cabernet sparkling.

Years ago had a chance to taste some in Tokyo in a private dinner, and I was really impressed by that one time experience, but could not recover the label of the red champagne of that particular bottle which was from Italy (I jotted it down but the paper went to laundary).

I am sure there are some food/wine experts here, and much appreciate any tips.

thank you
