Pure Cool Pear Ginger-Ice

This should be something I love. Over the past year or so I've fallen in love with low sugar "dry" sodas. They provide the bubbles and the flavors that I need without being anything more than liquefied sweetener. The thing is I think that a very small amount of sugar may be needed when drinks are carbonated. I still don't understand it after 32 years on this planet; if you drink a glass of water it's cool refreshing and tasty (in a tasteless kind of way), but if you take that same water and carbonate it the flavor changes. It acquires this taste that is borderline bitter. Is it the CO2 that I taste? I can only assume it is, and it can ruin drinks for me. If that added taste wasn't there this drink would be perfect. It has a light pear taste and there is a nice mellow ginger aftertaste. This is the kind of drink that you could enjoy after a nice meal. It's just too bad that I can't get over the "seltzer water" taste it has. Seriously, if this were uncarbonated I would probably be raving about it. Dear taste buds, please start liking the taste of unsweetened carbonated water. There is a world of drinks out there that are way better for us that we are just not enjoying because of it.
