Busch beer was popular back then because it was cheap. Not sure if they still make it.
They do. Here locally Henry Weinhard’s is selling for 4 cents per ounce. About the same price as Coke.
They still make it. And it isn’t any better than it was then. Just costs more.
I don’t know what it costs now, but it isn’t that much less than a decent regional craft beer.
Anyway, if a person can’t spend a dollar or two more a six pack to go from genuinely crappy beer to genuinely good beer they perhaps should not be drinking beer.
