My oldest granddaughter and I used to get together and try new "gourmet" root beer, and of course snacks like pizza 2-4 times a month. This was the best and our favorite for about 10 years now! In fact we liked it so much we still have the original bottles! Lower carbonation and much higher flavors! If you have never tried it, then you just don't like yourself!

Weirdly flat while not missing any contents. Without knowing where the seals on the swing top are sourced from, it sure seems like a material permeable to CO2.
