Hydrometers are standardized to 59°F (15°C), and when used in a sample at any other temperature, the observed reading must be corrected. This means if you take a gravity reading of a wort or must that is at a different temperature than the calibration temperature the reading will be inaccurate. Apply the meniscus correction to the actual hydrometer reading. Obtain the effective hydrometer depth (L in cm) for the corrected meniscus reading from Table 4-1.
