Brewing calculations
Residual or Real Extract gives a true measure of the residual sugar in beer
RE = AE + .4654(ABW) - .003615(ABW)2 / .9962
Original Gravity
OG = 100[(2.0665(ABW) + RE) / (100 + 1.0665(ABW)]
Alcohol
ABW = (ABV x 0.791) / Specific Gravity of beer
ABV = (ABW x Specific Gravity of Beer) / 0.791
Approximate calories per 12 oz.
Calories = [Grams Alcohol] x 7.0 calories/gram + [Grams Carbohydrate] x 4.0 calories/gram
Calories = [(Specific Gravity x 355) x ABW/100] x 7.0 + [(Specific Gravity x 355) x RE/100] x 4.0
Real or Apparent Degree of Attenuation
RDA = 100 (OG - RE)/OG)
ADA = 100 (OG - AE)/OG)
Extract in Wort Lincoln Equation
E(lbs. extract) = [(Wort Volume (Bbl)) (2.58/(1/OG(oP) - .00382)]
Theoretical Maximum Extract
TME = (Total Grist Weight (lbs.) x Weighted average Coarse Grind Extract As-is of grain bill)
Brewhouse Efficiency
Brewhouse Efficiency (%) = (Actual lbs. of extract in wort (Lincoln Equation / Theoretical Maximum Extract) x 100%
Mash or Kettle Salts
CaSO4 - approx. 29% Ca++ by weight
4.0 grams per Barrel of water or wort = 10 ppm as Ca++
CaCl2 - approx. 36% Ca++ by weight
3.25 grams per Barrel of water or wort = 10 ppm as Ca++
