Brewing At Work
I have begun to train on the Newlands brewing system at work .
It’s pretty amazing. It relates to homebrewing, signal flow through a tape machine into a mixer and outboard gear. There are many valves and switches, and pumps and even more mathematical formulas goinse, I have learned that it is best to figure out the total mash volume so you can measure the mash, the depth of both the water and grain in inches.
Also interesting is V1 x C1 = V2 x C2
10 gallons of wort at 10Ëš plato will be …
37.85Liters x.035 (evaporation rate will change due to weather, set up etc) = 1.32 L evaporates, leaving 36.5 liters / 3.785Â = 9.90 gallons.
So… if 10 gal is at 10ËšPlato, and you can figure your volume after boiling an hour – you can solve for your concentration ie final Ëšplato
37.85 L x 10ËšP/36.5 =Â 10.36ËšP
Also – hop additions.
Volume (L) x desired IBU / (Utilization % x AA% x 1000ml/L) = grams of hops.
So…Â 38.75 L and I want my IPA rockin’ with 60 IBUs of Columbus at 13.5 aa.
The only thing I am unsure of is how my utilization is at home. We’ll go with 30% which is traditional.
38.75 x 60 = 2325
.30 x .135 x 1000 = 40.5 Â Â Â Â 2325/40.5= 57.407 grams x .0353 (converts grams to ounces) = 2.02 oz of 13.5% aa Columbus hops to get 60 ibus in 10 gallons of water.
Why didn’t I pay more attention in algebra?
