Greetings all!
I have a 20 gallon batch of 100% corn (30 lbs and 15 gallons of water), which was cooked on 5/31. OG: 1.058 (seems a little low to me) pinched Red Star Distillers yeast (30g) next day to allow to cool around 90 degrees. Mixed well, today 6/7 checked SG = 1.014 (again seems to high after nearly 7 days fermenting....a few bubbles are continuing however I am thinking fermentation is close to being done.
Several questions:
1. Why is it taking so long to finish fermentation? Fermentation Temp is right around 74-76 degrees....
2. What is the target OG reading on a mash cook?
2. Did I not use enough yeast?
We are a start up and I am running test batches to get things dialed in, so today I am using city water (particulate filter in the line already), water conditioning guys coming next week to install a softner as well as RO. I will not be using RO to mash.
Cooked another batch on 6/5 (again OG was 1.058, waited until 6/7 (this morning due to working 6/6), there was a nice thick cap on top (thinking natural fermentation started) so I continued to pinch yeast, this time increased to 40g Red Star.
Thanks all!
