Maximizing Brewhouse Efficiency: Tips for Pro Brewers To Get Yours To a Consistent 90% | QFPB E004

In this episode of the Quality Focused Pro Brewers Podcast, hosts Hendo from Rockstar Brewery Academy and Adsy discuss the critical importance of achieving a consistent 90% brewhouse efficiency in a commercial brewery. They delve into the significance of monitoring the mill gap, calculating brewhouse efficiency, and differentiating it from mash efficiency. The hosts explain the factors that influence brewhouse efficiency, such as mash temperature, liquor-to-grist ratio, and lautering techniques. They also highlight the importance of regular mill gap checks, adjusting for different malt types, and proper use of grain sieves. Concluding with actionable steps, they encourage brewers to baseline their current brewhouse efficiency and work towards optimization. The episode emphasizes the financial and quality benefits of maintaining high brewhouse efficiency in today's challenging economic climate.

The formulae for Brewhouse for Brewhouse Efficiency% are:

Brewhouse Efficiency% = TE / TPE

Calculating Total Extract aka TE:

TE For Plato/BBL/lb brewers: TE = (((259+G)*G)/100)*WV

TE for SG/L/kg brewers: TE = G * WV

Where:

G = Gravity of Wort (Whole Gravity Units if using SG i.e. 1.047 = 47)
WV = Wort Volume @ Start of Boil

Calculating Total Potential Extract aka TPE:

Plato/BBL/lb brewers: TPE = SUM((WM1 * CG1)+(WM2 * CG2)+(WM3 * CG3) …. Etc)

SG/L/kg brewers: TPE = SUM((WM1 * CG1)+(WM2 * CG2)+(WM3 * CG3) …. Etc) * 384

Where:

WM1, WM2, WM3 etc = Weight of each malt/grain.
CG1, CG2, CG3 etc = Coarse Grind as-is percentage of each malt/grain from your CoA as a number e.g. 80.6% = 0.806
