Mug and A&W brands of root beer is good enough, but nothing equals Barq's...particularly for root beer floats with Breyer's vanilla ice cream. Yummy!!! (At least that's for wider distributed root beer...there are some smaller brands)
I always thought birch and root beer were similar flavors. Birch beer comes from the birch tree (gee, that figures). I used to love breaking off a green twig when hiking and leaving it in my mouth to taste it. I think root beer is that flavor plus some others.
Oh, and then there's ginger beer. I get that whenever I can, and I've been lucky to find places that sell it here in the States!!
