![]() ![]() ![]() Taking this reading is a critical measurement as it indicates the amount of sugar you can use. ![]() What this means is that you can tell how well your wort or must is fermenting by taking a reading of the original gravity (OG) before you add your yeast. If your liquid has a much different temperature to 20° C, you can also use an online calculator or app to calculate how the reading due to the differing temperature is effected. Using the same hydrometer and sugary water, now at 40☌ - 104☏, the water will appear to have a lower gravity. (This reads one point zero zero zero).Īdd sugar to the water, and the gravity will increase.Īdding alcohol to the pure water the gravity will go down as alcohol is less dense than water. The analysis of pure water at 20☌ - 68☏ will have a gravity of 1.000. Take care to use the same hydrometer for each measurement in the same experiment as different hydrometers may vary a little. This enables you to fill the right amount of liquid leaving a space at the top for the insertion of the hydrometer in order to test the results. The trial jar is 20cm long and has a diameter of approximately 3.5cm. It is much like a thermometer used for inserting under the tongue except that one end of it is fatter.ĭepending on how much the hydromtera floats or sinks in various liquids, you can measure how dense the fluids are.īrew Mart's recommendation is to use a trial jar which is a specific jar to use with the hydrometer for this purpose.Ī trail jar made from plastic is better than a glass one as the glass ones can break easily. The measurements/readings show how the yeast is turning sugar by volume and lets you know how well the fermentation process is coming along.Ī hydrometer looks like a round pointy glass rod with lines on it to use as a measurement. If you notice the amount of sugar going down, fermentation is working, and alcohol is increasing. In terms of brewing beer, wine or cider the hydrometer measures the amount of dissolved brewing sugar in the recipe. The easiest way to use a hydrometer is to collect a sample of the must (wine) or wort (beer) using a sterilised and rinsed wine thief (pipette), and a trial jar.Ī hydrometer is for use in any wine, beer or cider making situation. Much like in the Dead Sea, the more dissolved sugar there is in a beer or wine solution, the higher the hydrometer floats, giving a higher reading on the hydrometer's scale. The dead sea is so easy to float in because it is full of dissolved minerals. It works on the same principle as floating in the dead sea. It usually comes with a thin plastic case to help to protect it and uses a scale called specific gravity or just gravity for short.
