Well I'm never using a refractometer again...
Just pulled a sample out and checked it with a hydrometer and got 1.014 which is exactly where the recipe said it should be.
However, that means the OG reading I had was probably bad as well.
In the name of science I added some pure cane...
The mash temperature was 150°F (slightly lower than my target of 154).
I have been using a refractometer to measure SG. I've checked its calibration multiple times and it is reading 1.000 with pure water at room temperature.
I'll grab a larger sample and check it with the hydrometer.
Hi everyone, this is my first post here but I have been lurking in the background for awhile.
I brewed an all grain oatmeal stout (recipe below) back on Jan. 31st which went into the carboy at 1.054. I used a packet of safale US-04 in a 1 liter starter which had 24 hours to get going before...
