RE: Good places for bottle soda pop made with sugar
I tried the Popsoda site years ago. I was able to fill my need for Moxie (usually only available in New England, and even then it's with corn syrup), Cheerwine (only available in NC), and Verner's Ginger Ale. The sugar makes a lot of difference. Unfortunately, the shipping doubled the price. The company is a long way from my home in NJ, so I don't know if I'll ever order from them again.
FOrtunately, Boylan's is available in NJ. I strongly recommend them if you haven't tried them yet.
I also recommend the Manhattan Special Coffee soda and Dr. Brown's Cel-Ray (made with celery, which sounds like it shouldn't work, but it's really good.
