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++
