Yeah, Hoffman is great, but he’s not some infallible authority on every brewing method, though people treat him like one. In his video on specialty moka pots, he covers the Bialetti Brikka, the only moka pot that produces crema. He ignores all the very specific instructions that come with the Brikka, like use only 280 mls of water and don’t pre-heat it, then uses a random base rather than the special-sized base that comes with it, and fails to get it to produce crema. I still see coffee snobs claim that the Brikka doesn’t work because of that video.
