I see the value for American-style "espresso-flavored" drinks, or similar bottled/packaged products. But, yuck, who on earth wants to drink actual espresso at room temperature?

Fine for iced drinks or Americanos. Even drinks with hot milk might be ok. I guess it's not so great at a neat shit of espresso.

I do! I think almost everything tastes better at room-ish temperature. (Some things need to be colder or hotter to keep their texture, but I can't think of anything that _tastes_ better outside of the 16~25°C range)

Sparkling water (8-10C is the recommendation on the bottle in my hand). Bread (fresh from the oven, toast). Chicken Soup. And leaving aside examples, many things do taste better when they are hotter then 25, the heat helps more particles reach the olfactory receptors in your nose.

Very interesting for industrial use, that’s for sure.

For domestic use, in the home of somebody whose coffee snobbery is dialled to 11, I need far more information.

What beans were they using, freshness, etc? (Edit: Campos coffee… not on my shopping list that’s for sure…)

How did they control for extraction method differences to maximise output quality for all brew methods? (Edit: TDS and EY)

Were the “regular” coffee drinkers regular consumers of espresso?

Most importantly, how long until Hoffman does a deep dive and much will it cost so I can allocate budget for yet another coffee making device?

The target of this process is not the residential use, but industry processing.

Instead of heating water to extract coffee and then latter cooling it to freeze dry and make instant coffee you keep the whole process at low temperatures, saving lots of power.
