Taking Gravity Readings August 13 2014
Remember your hydrometer is calibrated for 60F (and meant to be read from the bottom of the meniscus). Hydrometer readings are useful in calculating ABV % and for checking on the status of your fermentation.
Refractometers are also great tools for reading gravity (in Brix). We suggest only using them for gravity readings pre-fermentation because the post-fermentation alcohol content can skew your reading.
