I'm making a blueberry Kolsch, and added concentrated blueberry juice mid-fermentation. I'm trying to figure out what the OG would be if I had added the concentrate right away. Here's my thinking:
Wort was SG 1.031. That's 7.8 Plato, meaning 78 g sugar/liter of water, which means 9 L of wort had ~700 g of sugar in it.
Blueberry concentrate was 68 Brix. I added 0.8 kg of it, which, at 1.35 SG, should be 0.6 L. 0.6 L @ 68 Brix should have ~410 g sugar.
Total 1110 g of sugar in 9.6 L is 11.5 P, which converts to an OG of 1.046.
Is this right? Is there an easier calculation?
