How long before James Hoffman finds out about this.

Waiting for him to appear in the YouTube shorts Brooklyn Coffee shop now I think about it.

It took me a few vids to warm up to his presentation style and the production style, but now anyone else doing coffee vids seems like a total amateur/influencer/YT rusher. Early Hoffman coffee competitions were the proof point for me that he’s not simply an influencer entrant.

His presentation still is still a bit forced and orchestrated to me, but at least I believe he’s smart and has interest in the craft.

I sent this to our electrochemist at work, maybe if we have some time we can test the coffee in the breakroom.
