Eh, the quote says it all; they're great at taking something and introducing it to the masses.

Funny thing is, I've seen cascara drinks advertised by Starbucks but didn't know what it was until now. I think they call it a cascara cold foam something or other so I thought 'cascara' was just a branding term for something to do with the foam or milk; I had no idea it was actually a 'thing'.

I don't frequent small coffee merchants in person (drinking Stumptown Cold Brew on tap at work as I type this!) but I've been to enough Storyville/Ladro/Stumptown type places and never seen it either.
