Okay, so I know nothing about coffee, I don't drink it, I don't make it for other people, apart from occasionally putting some espresso in cake, I don't even touch it. However I do watch a lot of youtube, especially during quarantine, and one of the youtubers I binged during this month was a coffee expert. His videos cover any coffee topic imaginable: blooming, brewing, equipment, storage, you name it, he probably has it (plus he has a really soothing voice so the videos are quite enjoyable to watch as ASMR).
Anyways, the channel name is James Hoffmann, I hope this was helpful.
