hop_calcs: Hop utilization calculations

In whanrott/fermentR: Converters and Calculators for Brewing and Fermentation

Description

Calculate hop requirements for brewing beer

Usage

hop_calcs(mh = NA, vw = NA, ibu = NA, aa = NA, utilization = NA)

hop_weight(vw, ibu, aa, utilization)

ibu(mh, vw, aa, utilization)

hop_utilization(mh, vw, ibu, aa)

Arguments

mh	mass of hops in g
vw	Wort volume in L
ibu	International Bittering Units in mg/L
aa	Percentage Alpha Acids
utilization	Percentage hop utilization

Value

the missing variable in the equation mh = (vw*ibu)/(aa*utilization*1000)

Examples

# calculate the weight of hops to achieve 25 IBU using Cascade at 10.3% Alpha Acids and 30 % utilization
hop_calcs(mh = NA, vw = 21, ibu = 25, aa = 0.103, utilization = 0.30)
# calculate the weight of hops to achieve 25 IBU using Cascade at 10.3% Alpha Acids and 30 % utilization
hop_weight(21, 25, 0.103, 0.30)
# calculate the ibu of using 17g Cascade hops at 10.3% Alpha Acids and 30 % utilization
ibu(mh = 17, vw = 21, aa = 0.103, utilization = 0.30)
# calculate the hop utilization
hop_utilization(mh = 17, vw = 21, ibu = 25, aa = 0.103)
