I don't like the taste of champagne
Is there something specific about champagne that you don't like?
I think it tastes like warm and sour sweat
I can understand that being your reason for not liking it. Everyone is entitled to their own opinion. Maybe you could try a different brand of champagne in the future, you might find out you like the new one.
Yuck, never drinking that shit again.
You can drink what you like. I do think it sounds like you probably got a bad bottle though. What is your favorite alcoholic beverage?
