Hi guys! I have a bottle of Lambrusco sparkling wine sitting around in my fridge, it’s kasher lemehadrin, and I’m considering bringing it over to my grandparents for Rosh Hashanah (they’re frum, I’m secular).
I know regular corked wine is perfectly ok, but this wine has a sort of waxy cover over a little metal cap with wires you need to twist off, and then you can pull the cork and let it pop. Which part of this, if any, could be ok on Chag, or on Shabbat for that matter?
Thanks and Shana Tova!
