    Decaf coffee has less than 1mg/ floz

    Black tea is generally over 5mg/floz

    Are you basing this on how alert you feel or do you have some very weak tea and some super strong decaf?

      I make decaf stronger because I like the taste but I also leave teabags in. I wonder how much variance there is between different decafs in reality. This is based on my own experience in my own body but I do suspect that not all decafs are made equal.
