A couple of Mexicans helped me drink it. It didn't last very long.
There is nothing particularly Mexican about the T.Ra.Sh. Mexican Lager.
It does use White Labs WLP940 yeast, which is called "Mexican Lager Yeast", which apparently originates from Mexico City. I guess that gives the beer something of a Mexican lineage.
But, when I think of Mexican beer, this is not what I picture.
