Strong(er) Coffee

[Acarpous]

Is there a reliable way of maximizing the amount of caffeine per oz of water? I am guessing hot water is the easiest, at least in a drip coffee setup.

Is there a way to know when an amount of coffee grounds is spent?

I found that I am drinking +32 oz of fluid between coffee, milk and OJ first thing in the morning and would like to prevent stretching my stomach more than necessary.
