    I'm relatively new to brewing, and I have not been able to produce a consistent post boil volume. I am small batch brewing on an electric range. What is the best way to determine how much evaporation occurs per hour?

    Take exact measurements

    Pre-Boil Volume
    Boil Duration
    Post Boil Volume

    Pre-Boil less Post Boil = Volume Evaporated

    Vol Evap/Time = Boil per Hour etc

    Your electric range should be putting a fairly constant amount of heat into the wort. The only variable really is the measurement. Check your measurements. If you're still having trouble, look at where you're setting the range. If it's anywhere other than on high, it may be cutting off the current if things get too hot, producing some variability in the boil rate. But if you're putting consistent quantities of heat into the wort, the boil rate should be relatively constant.
