Just out of curiosity, assuming we're at sea level, what effect does increasing applied heat to a boil have?
I'm trying to get a handle on my brew process and have a better understanding of what people mean when they say to boil vigorously, or boil moderately, etc...to me, boiling is boiling. 212F is 212F.
For instance, lets say my gas burner valve can be opened on a scale of 1 to 10. Typically, I crank it up to 7 or 8 to get a 6 gallon pot to boil from ambient. Once it reaches a full rolling boil, I can back off the valve to 3 or 4 to maintain the boil. Besides wasting money on propane, What would be the effect on the wort if I kept the valve wide open throughout the boil? Would I get increased evaporation? Would I get increased carmelization? Is it irrelevant since the wort cannot be raised beyond 212F without pressurizing it?
