They're all good to try once. Except the cream soda. That doesn't taste right. They should make Jones soda sample packs with one of each flavor. Like they do with Magic Hat, Sam Adams, and Sarnac.
Man oh man, I love Magic Hat Number Nine. I don't drink often, but it's great. So is Newcastle. It's like tea-beer. It doesn't taste like tea, but it's very light and it's british and there's a lot of flavor, so tea-beer seems like an appropriate name right now.
Also, real cream soda. Or creme soda. However it's supposed to be spelled, it's nice and golden and basically vanilla soda. Awesome.
