I'm afraid this flies in the face of my experience. Let me list the steps for using each implement, then "we'll do the math".Hydrometer
1. Remove a 100ml sample of wort - enough to fill the test jar three-quarters to the rim.
2. Refrigerate the sample until the heat won't shatter the hydrometer - approximately ten minutes, even in the freezer.
3. Immerse the hydrometer.
4. Spin the hydrometer.
5. Read the meniscus.
6. Repeat steps 3-5.
7. Record the reading.Refractometer
1. Remove two drops of wort - approximately 0.5ml.
2. Place drops on refractometer lens. Close lens.
3. Peer into eyepiece. Read the blue line.
4. Record the reading.
Gee, what do you
I think the hydrometer is a waste of time, wort and effort in the brewhouse. For example, how can you sample the tailings of your sparge runnings with a hydrometer? You simply can't, neither as quickly nor as effectively as with a refractometer. The refractometer is infinitely more useful in the brewhouse.
In the fermenting room, not so much. But in the brewhouse, only a lunatic would continue to use the hydrometer if offered a refractometer.
You are, of course, entitled to your opinion.
