The Boss Barista takeover is brought to you by Chobani.

A few weeks ago, I put a call out to coffee folks, fans, and drinkers across the globe to pitch ideas about the podcast they’ve been dreaming of making—and today we’re turning the mic over to the first in our series of guest creators.

Today we’re airing the first episode of the Updose Podcast, a show that chronicles American coffee in the 20th and 21st centuries.
