For me, getting a refractometer was one of those upgrades that made a lot of difference. With a refractometer you need a sample size of two drops. I figured that this would pay for itself in beer savings alone. I also had just broken my hydrometer and came to the realization that hydrometers are made of breakable glass that can break! 🙂

This is named calibration solution, but in homebrewing terms, I think it’s better thought of as a “double check you refractometer” solution. Calibration solution for SG and Brix refractometers… water. Distilled or RO water. This particular solution offers you a known gravity liquid (1.0264 sg) that you can use to double check your equipment.

It may be user error (and I admit I’m pretty ignorant regarding refractometers), but I have tried two different brands of this type of calibration solution unsuccessfully. After reading the label more carefully, it seems that this is intended for use with saltwater refractometers (not those intended for use with sugar solutions). I initially calibrated mine to 1.000 using RO water, then I tried this calibration solution. I got a reading of around 1.015 instead of 1.026. I then made my own sugar solution to compare my refractomer to my hydrometer and they were nearly identical (different by 0.001 SG points). So I wouldn’t recommend this for homebrewers.
Thanks for the feedback Stephen, much appreciated.
