You literally have to use multistage subcritical CO2 filtering to reach that level. Standard methods are not good enough.
This is somewhat poorly phrased. Methylene chloride is a neurotoxin and likely carcinogen, but it will be driven off by the roasting process. The boiling point of DCM is 40C, and roasting occurs at 200C, so any residual solvent should be long gone early in the roasting process. Nevertheless, this solvent is destructive to the ozone layer and should be phased out of industrial processes as much as possible.
TLDR: Swiss Water > paint thinner
It’s amazing how many things we use have been discovered by accident
I think it will happen at some point.
When I used to drink a lot of beer, I might have agreed with their sentiment, since I would mostly be drinking because I wanted the effect of the alcohol.
But since I stopped drinking alcohol, after several months I found, to my surprise, that a zero alcohol beer can be quite a pleasant experience. The taste reminded me of what I used to like about drinking beer with friends, whilst the differences helped me to stay connected to my new found appreciation of clarity.
I understand why, though some of us think of decaf "coffee", much the same way others view white "chocolate". At some point, the thing you modified it to be, isn't representative of the original thing. IMO, it should not be called coffee or chocolate, even with a descriptive adjective up front.
This is a minor nit to pick, but still, for those of us with a strong love of (addition to) coffee (or chocolate), its an important distinction.

Had a cardiovascular adventure some time ago. Caffeine was involved, and so I don't have. I agree decaf is a poor substitute, as is white, but they are all I can get.
The correct way to solve this is to remember that language is an imprecise medium to transmit ideas. White chocolate is chocolate because people consider it chocolate, not the other way around.

Seems that decaffeinating coffee is stranger than I realized!
You dont
Better just go to tea instead of decaf if you're sensitive. Another alternative that allows you to keep using coffee would be to go to your grandparents' coffee cups. They're 2-10 times smaller than the current ones!
I'm not trying to imply that coffee and cigarettes are equivalent in terms of harm, of course. That would be silly.
The most commonly used solvent is water. Ethanol is also a major one: https://www.worldofmolecules.com/solvents/
Or do we need to restart that program to ban all use of the horrible dihydrogen oxide solvent that pollutes over 70% of the surface of the world? ;)
Caffeine LD50: 150-200 mg/kg (according to Wikipedia).
Maximum allowed amount of methylene chloride in beverages, the dreadful paint thinner, according to the link above: 10 ppm, or about 2 mg per cup.
Methylene chloride LD50: 1.25 g/kg (again, according to Wikipedia).
I.e., you will literally die of caffeine poisoning long before the paint thinner gets you.
The fact that perfection is impossible to reach shouldn't make us abandon and do nothing about it.
