Default Is a "rolling boil" necessary?

Hey everyone. I have a new 5 gallon brew-pot that I tested today to see what the evaporation rate was like in it. I used 4 gallons of water and brought it to a boil on my gas stove. It hit boiling temperature and it was "rolling" in the bottom of the pot, but by the time those bubbles came to the surface they had broken up and the surface of the water remained relatively calm. Is this OK for brewing? I'm not sure if the purpose of the boil is the heat of the water or if it's the heat combined with the activity of the boil. Any thoughts?

If the surface is not moving, it's not boiling, it's simmering.

Yeah, that isnt going to give you the benefits of a boil.

It's hard to boil that much volume in a stovetop. Try to get the pot over multiple burners or reduce the boil volume to about 3 gallons.

That's the response that I was afraid of. I tried the dual burner for a bit. I think it might work, but it's just shy of covering both burners. I lose about half of each flame, therefore it seems a bit inefficient. It sounds like it might be time for a propane burner....bummer.

I always bemoaned the fact that my little electric stove could only handle a three gallon boil. So, I finally purchased a burner and it not only allows me to do full boils in the great outdoors it got me away from the screaming kids. Best purchase EVER!!

Ha! I can imagine! The only problem is, I live in upstate NY and it's going to get mighty cold this winter. A bit too cold for an outdoor brew in my opinion. But I might be able to rig up something where I don't freeze too much I guess. Or I just have to brew more often to feed my need....

Anyone know a cheap place to pick up a propane burner? Or recommend a certain brand?

A lot of people here buy the Bayou Classic turkey fry outfit...if you are in a somewhat inclosed area (garage) the heat from the burner should keep you warm enough. If not, what do you think beer is for?

Not to hijack a thread, but I've done one brew on a new Bayou Classic, and I was wondering where I should put the flame spreader for maximum heat. I had it about halfway up, and it could only bring eight gallons to a light boil. Would raising it give me more or less heat?

The purpose of the boil is to drive off DMS and other compounds that you don't want showing up in the final product. You'd probably be better boiling a smaller amount, getting it to "roll" an then adding distilled/sanitized water in the carboy.
