Driving up from Pacific Grover through Salinas, California on Hwy 101 you eventually arrive in San Francisco. Introduced in the 1940’s as Belfast Root Beer, it was bought out in 1986 by Pepsi. This would compete with A&W which was acquired by the Dr. Pepper/Snapple Company, and Barq’s, which originated from Mississippi, and has a contract with the Coke soda empire.
You can’t beat Mug as a basic smooth root beer. Its not gourmet, since
it uses corn syrup and doesnt have any fancy ingredients. It is really
good and they sell it at my favorite restaurant, the Hard Rock Cafe on Pier
Next we can drive over to Lodi, California to talk about the most popular
root beer in the world today, A&W.
