It’s been about 1 week now since I’ve ventured in my coffee roasting journey. So far it’s been interesting. This whole roasting thing turns out to be more involved that I thought initially.
At first I just thought that all I had to do was roast the beans. And that’s exactly what I was doing at first. Just roasting the beans. I read a bunch on the topic, and started to get familiar with the different stages of the roast and stuff. But reading about something and understanding and actually doing it and understanding what’s going on is not the same.
When you roast coffee, the beans are heated and go from green all the way to brown or almost black depending on what type of roast you are looking for. But along the way there’s a ton of reactions that take place inside the bean, and there’s also a ton of things that take place outside the bean as well.
First the beans absorb heat, then they start to turn pale and then yellow and then brown and then darken even more. Also water starts to evaporate from the beans, and you can smell different scents as the beans go through the roast.
Another thing that happens along the way, the beans have these crack stages. Where the beans actually start cracking and you can hear it. But like anything else, sometimes it’s more complicated than it sounds. There’s two stages of cracks, and sometimes it’s hard to hear the cracks at all depending on the coffee variety. Sometimes the 2 separate cracks almost run one into another, it’s hard to tell which crack you are in.
Then there’s time, the actually timing of the roast. How long the roast goes on for. How long you roast till you get to the first crack. How long between the first crack and the second crack. How long do you roast after the second crack. There’s a lot of timing involved.
Another thing you can look at is bean temperature. So yesterday I went out and bought a temperature probe to watch the bean temperature. I’ve only roasted one batch so far using the probe. But I think it will help out a lot, in knowing at what stage you are in the roast.
After the beans have been roasted, you’re supposed to let the coffee rest at least a day before drinking it. And then, some coffees taste better at different times after the roast. I’m not advanced enough yet to know which coffee needs how much resting time.
The other thing about coffee is how they describe the flavors of it. When you read about it, it’s almost like wine when they describe the taste of it. Well……. I don’t know what they are tasting, but I can’t seem to be able to do that. I guess that comes with time. But so far, I’m not seeing much difference in the way the different coffees taste. They all taste like……like coffee.
So anyway, I’m having a fun time experimenting. I’ll keep at it, and maybe in a few weeks and more experience I’ll be able to get awesome coffee and be able to differentiate all the flavors.
P.S. The picture of the coffee up top is of one of the roasts I did. It’s cool to be able to combine my 2 new hobbies like that. How does the roast look?
