Labels:text | black and white | newspaper OCR: TESTING D Hydrometers Unfermented wort is heavier than fer- mented beer, because malt sugar is heavier than the alcohol il festers. The hydrometer, a weighted plass float with a gender calibrated stem, measures A how much heavier beer is than water. C displaying the density where the stero emerges frem the beer. The higher the F density Che more malt in solution) the higher the hydrometer floats and the higher the reading. As the yeast eats the sugar compounds during fermenta- tion, the weight of the solution actually decreases, and the hydrometer sinks, displaying a lowe: reading. G The hydrometer is employed :wice while brewing: to determine the starting gravity, a good indication of the poten- tial alcoholic strength of the beer, and later when the beer has apparently fin- ished fermenting, to determine if the beer has reached final gravity and is safe C.
