MEASURING THE ALCOHOL CONTENT AFTER FERMENTATION
\nUse a Vinometer.
\nIf you havent taken before & after specific gravity (SG) readings, or want to check your calculations, you can use a vinometer.
\nA vinometer is most accurate in solutions containing little or no residual sugar.
\nThe vinometer works on the principle of capillary action, so it actually measures viscosity, which is dependent on the alcohol\/water ratio.
\nIt has a scale of alcohol content marked on it.
\nThe procedure is as follows:
\n* Fill the vinometer with some wine.
\n* Wait until some drops have fallen through. If the wine doesn\u2019t start to flow on its own, put your mouth on the bell-side of the vinometer and blow gently.
\n* Then put a finger on the part where the drops form and turn it upside down.
\n* Place the vinometer on a flat surface.
\n* Release the finger.
\nThe level in the capillary will drop to a certain level, which indicates the alcohol content of the sample
\n* Make at least two more measurements and take the average value of the measurements:
\nWHEN YOU PURCHASE THE HYDROMETER, YOU\u2019LL NEED TO KNOW:
\n* The range of readings, to make sure it will suit the purpose.
\nA standard range for home brewers is 0.990 to 1.120.
\nFor example, in order to achieve 12% alcohol, you\u2019ll want to start at a SG of 1.090.
\n* What the hydrometer measures.
\nSome hydrometers only measure specific gravity, but most of the home brew ones measure three things: SG, potential alcohol (P.A.), and sugar content.
\n* The calibration temperature of the hydrometer. The most common calibration temperature is 60 degrees F.
\nALCOHOL CONTENT USING BEFORE & AFTER FERMENTATION SG:
\nWhen fermentation has stopped, the final alcohol content can be calculated using the starting and final SG readings.
\nThe following formula can be used:
\nAlcohol content = (Starting SG \u2013 Final SG) \/ 7.36
\nExample
\nThe wine started with an SG of 1080, and ended with a SG of 992.
\nThe alcohol content of the wine should be: (1080 \u2013 992) \/ 7.36 = 12.0 %vol<\/p>\n","protected":false},"excerpt":{"rendered":"
