I'm very curious about SWP. How does it taste compared to good light roasted single origins?

In practice, it's far easier to find good single-origin roasts than to find good decaf options. I've actually never been able to find anything lighter than medium roast in SWP -- not sure if that's for some functional or taste reason, or just because it's a sliver of a sliver of the market.

Widely used chemical *(that was generally phased out in the 70s) linked to Parkinson's. Still important, but you don't need to start searching product labels in 2023 for it.

Trichloroethylene is still used but less than before.

~20 000 tonnes today vs. 250 000 tonnes in 1970.

Halogenated solvents should definitely be avoided at all costs but I'm generally not too concerned about how hexanes are used to extract cooking oil, for example.

Why not? I don’t know much about the topic, but I’ve wondered about it.

> Remember all the talk about how we should all eat lots of anti-oxidants to prevent cancer? It turns out it's more complicated than that, and an anti-oxidant rich diet can actually increase cancer risk. Which is probably because Mitochondrial Complex 1 inhibitors work by producing radical oxides in the mitochondria. I definitely agree with you that it's inherently very risky to mess around with them, but I also don'…

I think their point was - don’t do something daily with potentially powerful but unclear effects until we have some evidence on it’s long term safety. Unless there is a pressing, specific need (like cancer that may be worth the risk). Which seems reasonable?

Which I agree with. I'm definitely not advocating that people take this stuff. Only pointing out that it's not completely obvious that it's harmful.

It's volatile enough that it won't be present in the final product.

Volatile doesn’t mean harmful byproducts can’t be left behind, though.

I get your point, but isn't this kind of a broad statement? After all, ethanol is a hydrocarbon solvent, and it's been used in food applications for a long time.

Not to ruffle any feathers, but I notice this trend on HN also. People will post something the city they live in and drop all kinds of hints... except the name. Same for employers. Strange. It's like we need to play the old boardgame "Guess Who?"!

They don't want to deanonymize themselves.
