For some years I could not drink coffee because it caused me instant digestive problems. I tried various kinds of preparation and beans but often it only took some minutes until the bodily reactions started.
Then someone suggested to use the aeropress and now I can drink coffee again.
Can someone tell me a reason?
What I tried earlier: caffeine free coffee, espresso, old style filtered coffee, old style filters with adding cooking water by hand, modern automated coffee makers. Freshly ground, non freshly ground, mokka, adding powdered directly into the cup and surely some others I don't remember.
Now with the aeropress I used different kinds of beans and different mills, different filters (metal and paper) and never had any problems.
How I use the aeropress: I add two spoons of coffee, put a little hot water on it. After a couple of seconds I fill up to full, wait until some water is through, then gently squeeze.
I don't have any problems with caffeine.
