Novice Seeking Answers&Advice

[Daniel B]

Hi Everyone
My name is Dan and im new here.
I have a couple questions and seeking some good advice.
I'm new to drinking Sparklers. I had some Martini and Rossi Asti yesterday, and I have to say it turned me off. Sooo sweet and it was highly carbonated. I had it at room temp.-should it be drank at room temp. or be chilled.
Another thing about Asti--I cant find the sugar content on the bottle anywhere. Is it Dec, Semi-dec or what? Just the residual sugar content would be helpful, also , if you knew that--i tried googling and couldn't find it anywhere.
Another question. What is a very good extra dry sparkler? I've found that it is a great balence between Dry and Sweet. I tried Andre from Cali. and it tasted pretty flat (could be old?) It was good though.
My last thing is that I would like some advice on a good sparkler for my wedding. It doesn't necessarily have to be a desert wine. But I dont want Brut--its too dry for me.
I know this is alot of questions, and I thank everyone in advance for answering them.
