I feel somewhat differently than Adam on my decision to have it as the standard. As soon as you open a bottle of A&W you know you have a root beer. The spritz of aroma that leaves the bottle smells just like those little root beer barrel candy that you can grab a handfull of at the grocery store. He is also right about the taste. It too tastes strong and crisp of root beer extract. I, however, am not a fan of extreme carbonation. A&W is too rich in the bubbles for me, but that still doesn't block the fact that it tastes good. Perhaps the main reason I feel so strongly why this root beer should be the standard is the fact that almost every American can associate with it. Most have tried one or at least seen one of the A&W Drive Thrus that polka-dot the entire United States.
Let us know if you feel we are way off the mark on our standard. Also, please feel free to recommend root beer that you think will surprise the Rootbeer Brothers taste buds.
Bring on the root beer!
