I split a batch of 1.056 pale ale into four different carboys, and pitched four different yeasts. The four yeasts are WY1056, WY1318, WY1968, and WLP007. The beer has fermented for about 10 days and is done now. I thought I would take hydrometer samples of all of them a record the results, and I also wanted to test the refractometer reading against the hydrometer.
First beer: Yeast: WY1056
First hydrometer reading: 1.013, refractometer reading (adjusted in BeerSmith): 1.016
then I waited a couple of hours and took the readings again with the same sample
Second hydrometer reading: 1.011, refractometer reading: 1.010
Second beer: Yeast: WY1318
First hydrometer reading: 1.016, refractometer reading: 1.018
waited a couple of hours
Second hydrometer reading: 1.015, refractometer reading: 1.013
Third beer: Yeast: WY1968
First hydrometer reading: 1.017, refractometer reading: 1.020
waited a couple of hours
Second hydrometer reading: 1.015, refractometer reading: 1.020
Fourth beer: Yeast: WLP007
First hydrometer reading: 1.014, refractometer reading: 1.016
waited a couple of hours
Second hydrometer reading: 1.013, refractometer reading: 1.015
