I traded a few mudcrabs for a friend's non functional atomic coffee machine. I fixed it and have since been hooked on making coffee. So much so I wanted control over the whole process, so I built myself the rest of the components I needed. You can find more and pictures here: Imgur: The most awesome images on the Internet
Eveything works well, however the coffee is lacklustre.
I roasted my first batch of coffee beans for 35 minutes; they looked alright, but ground quite transparent and the coffee was very weak and not very flavoursome. The next attempt was for 45 minutes, much the same, weak dull coffee. I then roasted for 55 minutes and the coffee grounds were darker and produced a more full flavoured coffee, but it was still very transparent and thin, not the dark coffee I am used to.
It's not the machine or the grinder as I made good coffee between the trials, the only things I can blame are the roasting or the beans themselves. I have the Chinese beans from CS to practice with, they're small if that means anything, I'm not sure how they're meant to come out. The roaster is my home made jobby, it takes a long time, but I get the beans to an even roast.
Any idea where I am going wrong?
