Hi Guys,
I'd like to do an AG whiskey, my recipe and questions are as follows
5kg sugar from Corn
3kg sugar from Barley
2kg sugar from wheat
Corn:
Max yield = 84%
My assumed mashing efficiency = 70%
amount of corn needed is:
x = 5(0.84*0.7)
= 8.50kg
Malted Barley:
Max yield = 80%
My assumed mashing efficiency = 70%
amount of barley needed is:
x = 3(0.8*0.7)
= 5.35kg
Wheat:
Max yield = 79%
My assumed mashing efficiency = 70%
amount of wheat needed is:
x = 2(0.79*0.7)
= 3.62kg
Now from researching I have read an average Lintner of around 30-35 is required for full conversion, is this correct?
The barley I have selected is Barrett Burston Commander malt with an advertised WK of 311 which gives by my calcs a lintner of (311+16)3.5 = 93
The wheat I have chosen is Weyermann Pale Wheat, I can't find an exact Lintner on that wheat but it seems from reading that wheat typically has lintner values of around 60
the corn is unmalted, thus has no enzymes for conversion
so my average Lintner is = [(8.5*0) + (5.35*93) + (3.62*60)]/17.47
= 41
Now the corn at the brew shop is advertised at $7kg for flaked, is using feed grade corn like chicken feed suitable for whiskey?
Are my calcs correct? and is assuming a mash efficiency of 70% reasonable or too low/high?
Will I achieve full conversion based on the malts being used?
Can I use bakers yeast or will a brewing yeast be a much better option in terms of flavour?
Thanks in advance for any help
