I'm the one who prepares the ADC each day for the next morning. For
two of us I prepare it to make 11 cups, the 12 cup mark is a bit much
for us. Even at 11 cups sometimes there's some remaining but we don't
save it. Neither of us drinks coffee during the day,,, my wife is a
tea drinker, I drink plain water until evening when I prefer Sprite
with Crystal Palace. I see no point in xaving a cup of coffee unless
it's going to be used for cooking/baking.
