"LEGENDARY?"

"A legend (Latin, legenda, "things to be read") is a narrative of human actions that are perceived both by teller and listeners to take place within human history and to possess certain qualities that give the tale verisimilitude."

The beer may possess verisimilitude, but I'm not 100% convinced it's been around long enough to become a legend.

On the other hand ... It did "take place within human history".
