I used to believe that the first cup of coffee in the morning was always the best, that it was as good as it will get all day. As it provides a caffeine bump and positive start to the day. But now that I do more single cup brewing I am no longer sure it is the best tasting cup. I will post my two sentence punch line in a few weeks about what I have learned about my own coffee consumption, but was hoping you would indulge me and vote on which cup you find the best tasting or overall the most satisfying. The question assumes that you are brewing your own coffee with the same method all day long, so that there is consistency in the cup, so that the main variable is whether this is your first cup, middle cup, or last cup.
Obviously cup sequence number is not meant to be absolute. If you are a 3 cup drinker then 1st, 2nd, 3rd would apply, but if you drank 5 or 7 cups then maybe the 1st & 2nd count as first, while the last one or two count as last.
