The other is to use a cold water process to brew your coffee. I recommend Organic Coffee and the Toddy System. The Toddy Cold Water Process System has several benefits. It does not heat the oil from the bean, so there is less acid in your coffee. The acid is in the oil, and when there is less oil there is less acid.
Acid is what causes the jitters.
I have always thought that the caffeine caused the jitters, but I am told that this is not the case. I have tested it out on my art work. I'll send you to my special brewing instructions if you just click here . So there you have it . . .
