Understanding key equipment decisions empowers brewers to tailor optimal brewhouse infrastructure matching business objectives as startups scale towards wider distribution while retaining exceptional quality, consistency, and branding throughout growth phases.
The Brewing Process Using 7 BBL brew kettle
In typical brewery operations, the boiling phase utilizes 7 BBL kettles after initial mashing to extract sugars and add unique flavoring characteristics:
- Malted grains are combined with hot water in the mash tun for saccharification converting starches into fermentable sugars.
- The sweet liquid wort is then lautered through the grains to filter out solids while rinsing more sugars into the wort.
- The sweet wort is then transferred into the 7 BBL brew kettle where it reaches boiling temperature. Vigorous heating facilitates:a. Extracting aromatic hop oils contributing bitterness, flavor, and aromab. Concentrating wort to desired amounts through evaporationc. Promoting caramelization and Maillard reactions adding color and flavord. Sterilizing wort preventing unwanted infections
- After the boil phase finishes, wort moves to the fermenter where yeast are pitched to metabolize sugars into alcohol and CO2 while producing subtle flavor compounds.
The rapid heating and rolling boil inside the 7 BBL brew kettle represents a crucial processing step enabling craft brewers to create unique beer recipes that build brand loyalty with supporters.
