So how does that work? How does the laser help extraction? Is it like they’re just heating small bits of grounds over at a time for short durations only, as opposed to heating the whole heat and all the water at once? So still heat extraction?
- bertolomeos 4y agoA German article [1] summarizes the technique as using the laser to reduce the size of coffee grains without generating enough heat to break apart the aromatic compounds. Based on this explanation, I would say this method is not equivalent to heat extraction. https://www.scinexx.de/news/technik/skurril-cold-brew-per-laserpuls/ https://www.scinexx.de/news/technik/skurril-cold-brew-per-la...

- tmitchel2 4y agoSo yes still heating? Ah no I see the alternate explanation now
