Additionally, using an equation or spreadsheet to calculate the alcohol content (OG) from the refractometer reading will further improve the accuracy. . (ABV). Refractometers may not be the most convenient option for measuring volumetric percentage alcohol in wines or beers due to their dependence on the pH of the fruit; however, despite the . The Internet has handy ABV calculators that make this calculation a breeze. The basic calculation is this: ( Original Gravity – Final Gravity ) x 131 = % ABV. For example, let’s say your original gravity reading on brew day is 1.054 .This optical refractometer is designed for measuring of ABV (alcohol by volume, alcohol percentage by volume) of ethanol/water mixtures (optical alcohol meter).It is suitable for fruit brandies or other distillates which contain ethanol and water (Vodka, Juniper brandy, Bourbon, Whiskey, Whisky, distilled part of Gin, distilled part of Ouzo or Raki etc.). There are a couple of ways that the ABV and percent sugar equations can be derived for use with a refractometer. The first, and a common method of the online calculators is to measure with a hydrometer, and then measure with a .
Refractometers are a great way to sample gravity, however once alcohol is created during fermentation they will require a few calculations to correct the reading.

Maximum ABV assumes that 100% of the sugar was converted to alcohol (FG=1.000). While this is uncommon, certain yeasts can go this far. Expected ABV assumes 80% attention (AA). Your mileage may vary depending on the yeast being used. I have also tried the Bonham formula against a hand full of beers and got numbers like: ABV Estimated_ABV_by_refractometry 4.20 5.09531 5.45 5.85526 7.44 7.87441 6.10 6.9025 6.68 7.5389 5.83 5.78266 Now I didn't understand that you were comparing OE to TE. I have no idea as to whether Brix determined from RI would deviate more from actual Brix .
For brewers, ABV can also be determined using specific gravity readings taken with a hydrometer or refractometer. First, measure the original gravity (OG) before fermentation and the final gravity (FG) after fermentation. Two popular formulas are utilized: The standard formula is ABV = (OG - . If you’ve opened a bottle of beer or wine recently, you may have noticed the alcohol by volume (ABV) percentage on the label. The ABV tells you the percentage of alcohol (ethyl alcohol, or ethanol) content in an alcoholic beverage. . Refractometers measure the degree to which the light changes direction. In an alcoholic beverage, the amount .Refractometer or hydrometer to measure ABV when starting gravity is not available. Question . It's why you need an equation to use if for FG, alcohol is distorting the reading. The same thing is happening when taking the OG, it's just things other than alcohol. Reply reply

ABV = Alcohol by volume as a percentage (eg 4 would indicate 4%) Alcohol by volume based on current refractometer measurement and original refractometer measurement ABV =0.6967*(OGR-CGR) (extrapolated from physical model) Sugar by weight based on current refractometer measurement and original refractometer measurement
If your refractometer has a specific gravity scale (e.g., 1.050), don't use it. Many refractometers have an incorrect scale because they have used a formula for the cubic equation to convert from degrees Brix to specific gravity that was incorrectly published on byo.com. Take the Brix reading and use a calculator to convert it instead.
Negatives - After alcohol enters the equation you must go down deep rabbit holes and really understand what exactly you are doing to get fairly accurate results, though never as accurate as a hydrometer. Plus the added complexity contributes to user errors. Many if not most brewers will not use a refractometer for FG readings.
Equation (17) is then combined with Equation (18) to provide the Alternate ABV Formula. The Alternate ABV Formula is often presented for use with higher alcohol beers, but the basis for this is not provided and the .A refractometer is an instrument used to measure the concentration of a given substance in an aqueous solution. Brewers commonly use refractometers to measure sugar concentration in the wort, which can then be used to calculate beer or wine’s alcohol content. . (%ABV) they are NOT suitable for measuring the alcohol content of beer. This is . Measurement of ABV This is where it starts to get complicated. Fortunately Louis Bonham did a great job of researching this method for homebrewers. You need to take a reading with the refractometer as well as a hydrometer and use this equation: ABV = [277.8851 - 277.4(SG) + 0.9956(Brix) + 0.00523(Brix2) + 0.000013(Brix3)] x (SG/0.79)
Once you have SG and Plato values, you can calculate ABV using the following equation: ABV = (OG – FG) × 131.25. This equation uses the difference between the OG and FG values, multiplied by a constant figure (131.25). An example of this would be: OG in Plato = 11.2. FG in Plato = 3. Converting these Plato values to SG yields the following: You can calculate the ABV by using this formula: ABV= (OG-FG) x 131.25. How to use a hydrometer. . 760 mm Hg) measured by saccharometer, hydrometer, or refractometer with original gravity (OG) could be 1.050 and Final Gravity (FG) could be 1.010, then the alcohol by volume = 6.2 %.
The Hydrometer and Refractometer Calculator estimates the alcohol content of a finished wine from a refractometer reading and a hydrometer specific gravity (SG) reading. . H. S. Son et al. (2009) developed the following six empirical equations based on refractometer, hydrometer, and alcohol content measurements on 30 wines before and during .

Note that once fermentation begins and alcohol is present, refractometers become increasingly inaccurate. There are calculators to correct this, but even with a correction a calibrated Hydrometer is more accurate. The Simple ABV formula is used by most online ABV Calculators and is as follows: More useful would be the ABV level from final gravities as measured with a refractometer and hydrometer. ABV = 131 (OGH-FGH) reference (5) ABV = -357.4(FGH) + 1.421(FGR) + 357.4 Changes of 0.001 in the hydrometer reading can change the ABV by 0.5%. So it's important that this measurement is as accurate as possible.

The resulting cubic I got was ABV = 0.0572*brix^3 - 2.4305*brix^2 + 37.9142*brix - 178.0087. For the less mathematically inclined, this is just a formula we can use to predict ABV based on a refractometer reading. But the real question is how well it predicts ABV. If our predictions are constantly wrong, the formula isn’t very useful.In short: How to read a refractometer: To read a refractometer for sugar content, follow these steps: 1. Ensure that the refractometer is clean and calibrated according to the manufacturer’s instructions. 2. Take a small sample of the liquid you want to .
