I am not big on podcasts in general, except for My Dad Wrote a Porno, but I dabble a bit. And sometimes when you scroll down a bit, you can find beer related topics in unlikely spots.
Case in point, Stuff You Missed in History Class which, at the beginning of the year, had a perfectly right sized podcast about beer history. It was a fun 45 minutes that touched on multiple topics and had information enough for both beer newbies and those who know more (too much?) about the topic.
Idly scrolling can find some gems.
