An absolute must have for any brewer, amateur to professional. Nothing can go past the accuracy and no-nonsense faffin about than a trusted hydrometer. A Hydrometer Measures the density or specific gravity of a liquid. Used to give a reading to the gravity of your wort. Suspend the Hydrometer in a sample of your wort to get the reading in one of our 250mL Glass Cylinders or our 100mL Plastic Cylinder. To calculate your % Alcohol By Volume (OG - FG) x 131.25 = ABV % Where OG is your Original Gravity e.g. 1.050 as shown by your hydrometer before you pitch your yeast. and FG #34;Final Gravity #34; e.g. 1.010 as shown by the hydrometer after it has fermented. = ( 1.050 - 1.010 ) * 131.25 = 5.25% ABV
