I am considering adding some corn sugar to a recipe, and was trying to figure out in my head how much I would need.
In my mind, corn sugar is basically 100% soluble sugars. SG as I understand is a density relative to water ... so 1.000 is water, which would weigh 1Kg/Litre.
From that, I figured I could calculate the gravity quite simply... if I added .05 kg of corn sugar to 1 L of water, that 1 L of water should weigh 1.05 kg and the SG should be 1.05.
I followed this math out that if I wanted to increase a 20 L batch (~5gal) by 0.02 gravity, that I would need .02 kg /L x 20 L = .4 Kg or about 0.9lb
The recipe calculators don't agree... they come in about half... why is that? Where did I go wrong?
