Both Arthur and I preferred Jones Cream Soda to the other three brands. It wasn't really a close contest. For me, Shasta was the runner-up, with IBC and Sioux City clearly in third and fourth place. Arthur, however, liked Sioux City as his second-best sodas. Arthur liked all four brands, but I clearly preferred Jones and Shasta, and I wasn't too crazy about IBC or Sioux City.
The problem with this taste test is that we were missing two very good brands that I think I would have liked. Sprecher's and A&W Cream Soda weren't in the mix. I think these might be comparable to Jones and Shasta, but I won't know until we've tested them. And of course, I know that how well people like a food or drink in a taste test isn't really an indicator of what they will like if they are sitting and sipping a drink or eating a food over an extended time. Some foods that make a good initial taste impression in a taste test have flavors or other qualities that make them less enjoyable if you're taking your time and consuming them over a longer period.
We actually very rarely drink any soda. In our family we drink water mostly, and milk as well. Our family goes through about a gallon of milk each day. We sometimes have orange juice, grape juice, or apple juice, and on special occasions we'll get some other sort of juice like berry juice or one of the blends that has pineapple or mango in it. I'd estimate we might have an average of two soda cans or bottles per month, if even that much.
