If you ere put root beer, made by 3 or 4 different companies would you be able to tell which companies root beer you are drinking?

It would be like the pepsi test test, expect for you have to test and see if you can pick 3 or 4 of the companies and see whose root beer you are drinking. So say if the 4 were Barq's, Mug, A&W, and Dad's root beer, would you be able to correctly say which root beer is which. Say if you were served, Barq's rooter first, A&W second, Mug third, and Dad's root beer forth, and it it doesn't have to be these 4 root beers, or in the order I post them in.

I can pick out AW The rest all taste the same. I can also pick out the difference when it comes from an actual keg. It is like tasting ginger ales, they're all the same and then there is Vernors.
