For a beginner's first brew, I'd allow 4-5 hours. That should give him enough time to learn the equipment, read a few things, and then brew. I'd highly recommend a stove-top extract kit for the first brew. Less mess, less time, easy to follow, difficult to ruin...yada yada yada. If he gets hooked, like the many of us, watch out...you might have to share his heart with his brew hobby. My wife still loves me!
