Hi Joyce, there’s no proper glass for sparkling wine, it’s up to you and down to personal preference. But I find that flutes do not allow to swirl the wine and to smell the Champagne properly. Flutes are made to allow to see the flow of bubbles coming up but not really to appreciate the aromas of a wine before tasting, that’s why I prefer standard wine tasting glasses. I talk a little bit about it here in this video, around minute 6:30 https://www.youtube.com/watch?v=zKqfBGnMQfQ and I talk about it quite often on my YouTube channel when I have sparkling wine videos. I’m actually going to be releasing a video talking about wine glasses soon, so stay tuned 🙂 Hope this helps. Cheers
