Update: To find the alcohol potential, this calculator uses the alternate ABV equation which you can read about here. Remember that hydrometer readings need to be temperature corrected. You may want to check our Hydrometer Temperature Adjustment Calculator if you are getting samples at other temperatures. See Also: Other wine calculators by Brewer's Friend. What is a refractometer? A refractometer measures the sugar content of a solution via the refraction of light. It performs a similar task to the hydrometer, but is far more convenient to use.Most refractometers give a reading in Brix, and some in specific gravity.. One benefit to a refractometer is that most models have an automatic temperature conversion, . This pre-fermentation reading is called the “Original Gravity” and the post-fermentation reading is known as the “Final Gravity”. Most homebrewers use a hydrometer or refractometer to take gravity readings throughout the process. If you’re just getting started, we recommend using a hydrometer, which is cheaper, .where: a v = alcohol content, % by volume. B i = initial Brix reading. B a = refractometer Brix reading (apparent Brix). B h = hydrometer Brix reading. B t = true Brix (% solids by weight). Equations (5-24) and (5-25) allow calculation of alcohol content and true Brix directly from hydrometer and refractometer readings.
A slightly more accurate conversion formula is: SG = 1.000019 + [0.003865613(Brix) + 0.00001296425(Brix) + 0.00000005701128(Brix)] . To calculate your correction value, measure the specific gravity with your refractometer. Then chill a sample of your wort and measure the gravity with a hydrometer. Convert the hydrometer reading to Brix using .Calculating estimated Final Gravity. When calculating estimated final gravity three variables come into play; Yeast attenuation, Mash temperature and Ingredients that add increase the density of the wort but are either partially or not fermentable by the yeast, like lactose. These points are calculated separately and added to the OG and FG at .When taking a refractometer measurement of wort, the Brix reading is not necessarily accurate. What is obtained is the Brix WRI (wort refraction index). Only after dividing the Brix WRI by the wort correction factor is the actual Brix known. It is helpful to know that Brix and Plato are nominally the same to 3
The equation to calculate fermenting beer gravity is a bit complex, so the quickest way to convert your raw refractometer reading to a specific gravity is to use some brewing software, an online calculator (many homebrew supply websites have free calculators available), using a spreadsheet, or using software like BeerSmith or Brewer’s Friend etc.Final gravity is a measure of the amount of fermentable sugars in the beer after fermentation. To calculate final gravity, you will need a hydrometer and a calculator. The formula for calculating ABV is: ABV = (OG-FG)*131.25. For example, if your original gravity is 1.050 and your final gravity is 1.010, your ABV would be 4.6%.

Update - October 2012 A browser cookie will now save your hydrometer calibration between visits (but if you clear your cache it disappears). Update - August 2012 This calculator now supports different hydrometer calibrations. Look on your hydrometer (or its instructions) and it should tell you. Old hydrometers are calibrated to (59° F / 15° C) and newer ones are typically (68° F / . The refractometer measures the sugar concentration of a particular liquid. It will register both complex and simple sugars. Once fermentation begins the presence of alcohol distorts the refraction thus requiring you to use a conversion chart or calculator to determine the remaining sugar. A refractometer is a more advanced brewing tool for calculating specific gravity. It has some pros and cons in comparison to using your trusty hydrometer and can be used throughout the brew day when a hydrometer doesn’t always make sense. While a refractometer is not going to replace your hydrometer altogether (my original misconception), it will certainly .
Current/final gravity (FG) Current Gravity (CG) or Final Gravity (FG) is a measure of specific gravity, at 68ºF (20ºC), at the conclusion of fermentation and is directly related to Apparent Extract (AE). Specific gravity readings can signal the end of fermentation when they stop moving.
Final gravity: 1.002 – 1.006. Alcohol by volume: 1.040 – 1.006 = 0.034 x 131.25 = 4.5%. Hydrometer Pros. A hydrometer and test jar can cost less than .00; . If the scale is in another measurement, you can use a refractometer calculator to convert to Brix. Refractometer Pros. Very simple to read; A few drops of wort is all it takes for . Final Gravity Adjustment. One area where the hydrometer remains superior to the refractometer is in measuring final gravity (FG). Unlike reading a hydrometer, which simply floats in the mixture of water, sugar, and ethanol that we call beer, using a refractometer to get FG is a little tricky. The alcohol will change the reading given off by the refractometer however there is an equation that only needs the original gravity. I use an iphone app called brew pal and just turn alcohol correction to "on". Also get used to taking your readings in Brix, even if your refractometer has SG readings because the calculatins use brix as input.Here's a step-by-step guide on how to measure beer gravity. To do this, you'll need a hydrometer or a refractometer, a sample jar or test tube to collect your . Final Gravity (FG): This is the specific gravity of the beer once fermentation has finished. It indicates how much of the sugar has been consumed and converted into alcohol and carbon .
About The Calculator. To make the OF FG calculator easier to use, default values have been set for the average brewhouse efficiency, yeast attenuation and batch size (5 gallons).. If you are un familiar with these numbers and how they influence the calculations to find your beers specific original & final gravity, you can learn more by checking out the examples below or simply . FermCalc uses an iterative technique to solve equation (1) for B given a value of sg.For values of sg less than 1.0, the slope of the B vs. sg curve at sg = 1.0 is extrapolated to lower values to obtain the associated negative Brix values.. Previous versions of FermCalc used the sucrose conversion table in the USDA Technical Procedures Manual for this conversion.
