I recently moved apartments and my gas stove in my new apartment is strangely weaker than the electric burner I was using in my old apartment. I am an extract brewer and have been fairly pleased with my results, I try as much as possible to do full volume (6 gallons starting for a 5 gallon recipe) boils. While my new stove is quite weak it does eventually get the wort to 100 C. However there is not that much motion on the surface and I definitely would not say the boil is "rolling." Is this a problem? Is there a benefit to having a vigorous boil or is the fact that the wort is 100 degrees sufficient? Also if it helps, I am getting a decent hot break.
