I don't drink many soft drinks. Once in a while I'll have a ginger ale or root beer and, on those rare occasions, I look for the drinks with all natural ingredients. My brother-in-law came across some fizzy drinks I have to tell you about (if you haven't already discovered them). I think he found them at Big Lots. My father-in-law then went searching for them and found some other flavors.
Some are made by Santa Cruz; these are all organic. They found Ginger Ale, Lemon Lime, Raspberry Lemonade, and Root Beer. So far I've tried Ginger Ale, Raspberry Lemonade, and Root Beer.
The others are made by R. W. Knudsen. These aren't organic, but they have natural ingredients and no added sugar. They found Lemon Lime (80% fruit juice), Orange Passionfruit (85% fruit juice), Jamaican Lemonade (90% fruit juice), Ginger Ale (80% fruit juice), Boysenberry (100% fruit juice), Cranberry (100% fruit juice), and Raspberry (100% fruit juice). When the can says "100% fruit juice" they've added enough sparkling filtered water to reconstitute the juices. Of these I've tried Orange Passionfruit and Raspberry.
I particularly enjoyed the drinks with fruit flavors. The ginger ale and root beer were good, but if you prefer a bite to your ginger ale or a LOT of fizz to your root beer, you might be disappointed.
All the drinks I've tasted were mildly fizzy with a light flavor. They also didn't feel heavy in my stomach, if that makes sense. Another bonus: each 6-pack was $2.00. That's only $0.33 per can!
