Let me first say that I am not new to AG brewing (since 1997).
Yesterday, I brewed Yooper's AG Oatmeal Stout and added cocoa powder (paste) to the boil.
After chilling, I got a 6/2% Brix reading from my new refractometer. I did not take a hydrometer reading as I checked the conversion after cleaning up.
I mashed for 90 minutes and did a 60 minute boil per Yooper's instructions, but based on the conversion, I got nothing in the way of potential alcohol in the wort.
So far, about 18 hours and not noticable activity in the airlock.
Besides the refractometer being off and it is brand new, or me being totally stupid and not able to read the chart, how can I do this?
