A friend of mine has brought me a few “packs” of coffee from Taiwan that allows you to make filter coffee on the go, with just a cup and hot water.
It works kinda the same way as a tea bag, except it sits on top of your cup, holding the coffee on which you will do your pour-over.
Want to see how it works ? Check out the video above to see it in action. As for the taste, I guess it depends on the brand you buy : apparently those things are EVERYWHERE in Taïwan, available with lots of different kinds of coffees, roasters, etc.

I have a few friends who are in the 3rd wave coffee industry here in Paris, I’ll try to show it to them to see if they want to give it a try for themselves.
The Brûlerie Belleville has taken another path : they are making instant coffee with premium, fresh roasted beans. I’ve had the possibility to try and it does taste way better than 95% of the instant coffee out there, but it still has a hard to describe “instant-coffee taste”.

It’s probably due to the simple that it simply is coffee that is dehydrated and then re-hydrated in your cup. Orange juice from concentrate can be 100% chemically similar to freshly squeezed orange juice, it still doesn’t taste the same.
The human palate definitely has more subtlety than what our current chemical analysis can measure, and I think it’s blessing rather than a curse.
