This is fascinating from a food technology standpoint.
But the framing of the article around espresso specifically is somewhat bizarre. Most people want their shot of espresso to be piping hot, not room temperature. And most iced coffee is very intentionally not made with espresso (although you certainly can use it if you want).
The text of the article seems to suggest that this is more intended for "making ready-to-drink coffee products at industrial scale". But then that is not single-serve espresso shots that the article shows in several images.
So is this about room-temperature espresso shots (not what most people want) or about industrial-scale concentrated coffee? And if it's the latter, what would those machines look like? It's one thing to use ultrasound at a small scale; but what about in gigantic basins? Does that work, or are there challenges? Is this tech that scales?
- stevage 4mo ago> And most iced coffee is very intentionally not made with espresso Really? How is it made?
- PoorlyNamed 4mo agoBy soaking regular ground coffee in water for 12 hours or so.
- tasercake 4mo agoYou may be thinking of cold brew, which is usually more expensive due to the higher coffee-to-water ratio. A standard ‘iced coffee’ at most coffee shops is espresso-based
- PoorlyNamed 4mo agoHuh. I never drink cold coffee so I always assumed they were one and the same. Thanks for the correction.
- crazygringo 4mo agoThis is not true. A standard iced coffee is just regular brewed coffee that is then put in the fridge. (Which is different from cold brew which is brewed in the fridge.) Absolutely not espresso-based.
- crazygringo 4mo agoBy making regular hot brew coffee and putting it in the fridge. If you go to any random cafe and asked for an iced coffee, that's what they're going to give you. If you want something else, you have to ask specifically for cold brew, or a specialty drink like an iced latte or something.
- fiatpandas 4mo agoIced lattes are a pretty common drink and near ubiquitous menu item.
- mminer237 4mo agoIced espresso drinks are the large majority of what people buy at, e.g., Starbucks.
- crazygringo 4mo agoMost iced coffee that people buy is not iced espresso drinks. Those are specialty drinks. Think an iced coffee from Dunkin Donuts or McDonald's or whatever instead.
- mminer237 4mo agoEh, I think lattes are definitely the most popular drink at Starbucks and Dunkin.
