A regular espresso machine uses high pressure to brew a very short, thick, very concentrated shot of coffee. But is it concentrated enough?
The Ultrapresso would brew a standard espresso shot, but then pipe it to a reverse osmosis filter where some of the water is filtered out, leaving a(n even more)
highly concentrated shot of coffee goodness.
Reverse osmosis is already used in making concentrates and syrups, and it preserves most of the aromatics that would evaporate or denature with other methods of reduction.
The end result wouldn't be a burst of flavor as much as a kick in the teeth.
So. Thoughts?
I wonder how they make this?

The coffee bean seems similar to the cacao bean.
When they make chocolate, they grind up the beans into powder... and then keep going, and it becomes a sort of thick liquid. |
|

Maybe the same would happen for coffee beans. If so, you could make 100% coffee, no water. Would that be concentrated enough for you? |

A PhD student I knew used to eat instant coffee powder with a spoon sometimes. |

Jot (link) claims to have “a proprietary extraction process” - whatever that is - to make their 20x concentrate. Dunno if reverse osmosis is involved. |
|
| |
Yeah, that's not unusual among PhD students, IIRC. |
|

a1, I looked into that, and found an interview with the co-founder (link). Apparently Jot is 20x more concentrated than "traditional coffee", and for comparison they say espresso is "only" 14-16x. And their process is just adjusted brewing, tweaking the temperature/pressure/time, no filtering/reducing/osmoting. |

Osmoting is totally a word, I checked the dictionary. |

I wouldn't put up with a time waster like that. You can tip it straight from the jar and avoid having to find a spoon, clean a spoon, use a spoon, clean a spoon again. |

They'll likely be putting it under a partial vacuum and just boiling off most of the water. |
