Thats a widely spread myth. As we can see myth is even in the books The melting point of the compound is 235° Celsius, something one cannot reach even with Starbucks-level olive black charcoals. What actually decreases with roasting is chlorogenic acid, a specific antioxidant found in coffee beans and that some people associate with stomach issues and anecdotally claim darker roasts are better for them for this reason

I’m know nothing related to coffee bean roasting and caffeine levels, doing some reading via Wikipedia , a very enlightening read,

Coffee roasting - Wikipedia

en.wikipedia.org

The article states:
“Caffeine levels are not significantly affected by the level of roast. Caffeine remains stable up to 200 °C (392 °F) and completely decomposes around 285 °C (545 °F). Given that roasting temperatures do not exceed 200 °C (392 °F) for long and rarely if ever reach 285 °C (545 °F), the caffeine content of a coffee is not likely changed much by the roasting process. Despite this, and the common misconception that darker roasts will always contain more caffeine than lighter roasts, when beans are roasted they lose water and expand. As a result, when ground and measured by volume, the denser lighter roast will contain more caffeine than the darker roast.”


Now Home roasting beans, anyone here doing it?

Home roasting:
“Home roasting coffee;
Home roasting is the process of roasting small batches of green coffee beans for personal consumption. Even after the turn of the 20th century, it was more common for at-home coffee drinkers to roast their coffee in their residence than it was to buy pre-roasted coffee. Later, home roasting faded in popularity with the rise of the commercial coffee roasting companies. In recent years home roasting of coffee has seen a revival. In some cases there is an economic advantage, but primarily it is a means to achieve finer control over the quality and characteristics of the finished product.”

Visited my daughter at her apartment, we made espresso with my old machine, then played card games amongst us 6 people.

Just neat connecting thru our love of beans and stuff.

Had an excellent large Espresso from my absolutely delicious Mexican beans, that is on the darker side, but quite sweet - while watching the great but confusing s2 final of Silo.
I’m now reading up on that serie while finishing my cup.
Yes, the heat last that long in my cups with a lid on it.

I need to cut down on coffee for medical reasons, or to be more exact, cut down on the caffeine.
Will still be able to enjoy a cuppa or two a week of oldschool coffee but thinking of replacing the rest with decaff.
I realize that asking for advice on decaff beans might be like cursing in the church here but do any of you have any experience or good advice on what to go for?

As far as I have understood there's a few different ways on getting the beans "decaffeinated".

If I was instructed by a doctor to avoid caffeine, I would most certainly do exactly what you are doing -- look for palatable decaffeinated options. I enjoy coffee way too much to just give it up. I cannot really make any recommendations though but if I were to start down that road I would first look at my current sources of beans who I know I like. I would expect the decaffeinated to be less bitter or acidic / have less dark chocolately-type notes and to be more sweet. That is okay with me. I am confident I could find something pretty good.

No roasting here nowadays, but quite a lot earlier, long time ago.
It smelled everywhere after doing it in the oven though.

My brother travelled everywhere and sent/brought home beans from lots of various locations.
You can store the green beans at least a very long time, to forever, before you roast them.
If I was to roast beans today I would use the popcorn machine - I've heard people do that successfully.
I recall I saw a not so small bag of green beans somewhere here, for quite some time ago - but didn’t felt compelled to use them - so I forgot where it was again. 😂

We’ve got the “real” oil based popcorn machine, so like ours shown below?
If so cool, I’ll have to try it out, just to do it.

Used to do outdoor movie nights on weekends when kids were young.
