My wife and I enjoy drip coffee, french pressed coffee, espresso, black tea, green tea, and just about anything caffeinated.
However, my wife wants to avoid caffeine due to its physiological effects.
Unfortunately, in her words, decaf espresso "tastes horrible," and I agree. I have similar feelings against decaf black tea.
Is there anything with a bitter flavor similar to caffeine that could add some of the punch back to decaffeinated coffee or tea?
