I am assuming the grounds were "used"...in which case most of the caffeine content has already been washed from them...I don't know percentages as there do seem to be some real knowledgeable folks on this board, but as long as it wasn't much, you've got the added comfort of knowing they were not fresh, fully potent coffee grounds. (Have you ever been so deperate as to be forced to re use grounds and try to squeeze another cup out of them...miserably weak excuse for a cup of coffee.) |
