Description
It seems like every stone carving of ancient brewing has the Brewer with their concoction sitting on top of a fire pit with steam rising out of the cauldron. Why those early Brewers saw a need to heat the liquid may be a mystery to any one observing? However now we know that sterilization of the wort is critical to ensuring that the yeast will not have any competition for the nutrients and carbohydrates that we worked so hard to create during Mashing. So Boiling, like malting, mashing, and lautering is a very important step in the brewing process. Like those steps mentioned, consistency in the process will lead to a predictable outcome. The Boiling process is also expensive considering the amount of BTUs that goes into the wort during heating and then pulled out during cooling. So Wort Boiling needs to be done with care and vigilance.
