How can I maximize the caffeine content of my coffee? Like many people, I rely on coffee in the morning to really get me going for the day. I always use more than the directions require to get more caffeine for that extra morning jolt.

How much ground coffee should I use to reach caffeine critical mass in my brew? Is there a formula for volume of grounds per unit of water that I can use so I can get the maximum caffeine experience without wasting coffee?
Use lighter roast coffee: caffeine burns off as the roast darkens.  All other things equal, though, the stronger the cup of coffee, the more caffeine will be in it.  You aren't going to reach caffeine saturation just by brewing (even very) strong coffee.  So brew coffee with lighter roasted beans to your maximum desired strength.
