This question is information seeking rather than problem solving...
I see many posted recipes with prolonged boil time (90min 120min, etc). I understand if you're making a big beer with a huge grainbill, the extra boil time is needed to come down to volume. But many times I see a "normal" grainbill (10-15 lbs) boil for 90 or occasionally 120 minutes to come down to 5 or 6 gallons. Mechanically, I understand you'd need extra sparge water to do this, but what is the purpose for a prolonged boil? What characteristics (positive and negative) do an extra 30 or 60 minutes of boiling impart to a beer?
