Home Brew How to Calculate Malt Weight
Home brew how to calculate the malt Weight if get 1000L Wort with density 13 Plato
Malt Weight = Wort Density x Wort Volume/ (Max. Yield x Extract Efficiency )
Extract Efficiency: We take 85% (share next time)
2-RowLager Malt Typical Yield: Max. 80%
Wheat Malt Typical Yield: Max. 79%
(Typical Yield of Malts, we can get information from malt supplier,on line or books)
Here we roughly think °Plato is equivalent to Gravity, if we want brew 1000L Wort with density 13 Plato
From the aboving descriptions
we can calcualte the actual malt quantity
Malt Weight = 13% x 1000kg/(80% x 85%) = 191kg;
If 2 type of malt needed. Like wheat beer use Barley 1, 60%; wheat 2, 40%
[(Wort Density x Wort Volume)/ Extract Efficiency] x (Weight Percent1 / Typical Yield 1 + Weight Percent2 / Typical Yield 2 )
Barley Weight = [(13% x 1000kg)/85%] x (60% / 80% + 40% / 79%) = 192kg
Barley Weight 1 = 192kg x 60% = 115kg
Wheat Weight 2 = 192kg x 40% = 77kg
Anyway, brewing is not a science.
We can brew we want, Let’s brew together, and enjoy the gift from God.
