The refractometer research of Petr Novotny has far eclipsed that of Sean Terrill, and a Novtny based FG calculator will give far more accurate refractometer based FG .
This Refractometer Calculator helps brewers convert and correct refractometer readings for more accurate gravity measurements. Here's what you'll learn: Original Gravity (OG) .
If you are an extract brewer and want to know your expected original gravity (OG), expected final gravity (FG), and expected alcohol by volume (ABV), you can plug in the numbers and get instant results. This calculator is specifically .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. The calculators below will convert Orignal Brix to Original Gravity (pre fermentation only) and will convert Original/Final Brix to Final Gravity and ABV% (during and post . Using a refractometer is possibly the quickest and easiest way to check gravity throughout the brewing process. A refractometer is not as commonly used by homebrewers as a hydrometer but I find using one is much . 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, so .
In practice, this means that in order to calculate the true gravity of a fermenting or fully fermented beer, you need not only the current refractometer reading, but also the starting gravity. So if you are using a refractometer, it is critically important you record the starting gravity of the wort before fermentation if you want to calculate .This works fine for most common beer types. However, this formula becomes less accurate with progressively higher alcohol content. The Most Accurate ABV formula takes into account that the fluid measured in the Final Gravity is no longer only water with dissolved solids since it now contains alcohol. So, if you are brewing strong beer, the difference becomes relevant. Now that we’ve discussed how various environmental factors can affect the results from a refractometer reading, let’s move on to discussing how you can use a Beer Refractometer Specific Gravity and Alcohol by Volume Calculator, incorporating a chart, calculation and site with final gravity for more precise readings, using the right method .To calculate final gravity, you will need a hydrometer and a calculator. The formula for calculating ABV is: ABV = (OG-FG)*131.25. . refractometer or digital brewing software, and using the formula ABV = (OG-FG)*131.25. You can also calculate ABW (alcohol by weight) by multiplying the ABV by 0.79336. .
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 / .

(degrees F) Using your hydrometer Find the measured final gravity of your brew : The Actual Final Gravity Is: This reflects the actual % (by weight) of disolved solids in the brew .
Nvotony's article on his refractometer research into beer FG's is published in Zymurgy's July/August 2017 issue. I just noticed that Brewer's Friend has switched their online calculator over to one of Novotny's formulas. PM me and I will email you a copy of my Novotny quadratic method based calculator.
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.
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 .
This article discusses the theory, calculations, and method used by the Grainfather community app to calculate the original gravity (OG) and the final gravity (FG) for a beer recipe. Gravity. Gravity refers to the density of the solution. In wort, we are dealing with two items contributing to the overall density of the solution.However, for measuring Final Gravity with a refractometer, a special calculator is required once alcohol is present in the beer. We offer a Refractometer Calculator here. For helpful tips on how to boost the ABV of your homebrew, watch our video Boosting Gravity: How to Increase the ABV of Homebrew (AND Maintain Balance). Most homebrewers use a hydrometer or refractometer to take gravity readings throughout . by comparing the Original Gravity (OG) measurements (rows) and Final Gravity (FG) measurements (columns) Final . 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 .
What is a refractometer? A refractometer is a tool used for measuring concentrations of aqueous solutions.It has many applications across food, agricultural, chemical, and manufacturing industries. A refractometer can be used to measure things like the total plasma protein in a blood sample, the salinity of water and even the amount of water content .For example, if you have an Original Gravity of 1.050 and an Final Gravity of 1.010 the calculation would be, ABV=(1.050−1.010)×131.25=5.25. Your beer would have an ABV of approximately 5.25%. Gravity and Beer Styles. Gravity, specifically the Original Gravity (OG) and Final Gravity (FG), plays a significant role in determining the character .
To calibrate a brewing refractometer, you will need to pick up some distilled water. Instead of placing drops of wort or beer on the sample plate (angled prism), place distilled water on the prism. Distilled water should read exactly at 0. . How to Calculate Final Gravity with a Refractometer. As stated above, a refractometer does have some .The correction factor is different for different breweries. Beers that are very dark or have a very high starting gravity may also require a different correction factor. 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.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.
Use Cases for This Calculator Estimating ABV for Homebrewing. Calculate the Alcohol By Volume (ABV) of your homebrewed beer accurately to determine its strength and flavor profile. Enter the original and final gravity readings to get the precise ABV percentage, helping you adjust and improve your brewing techniques. Testing New Recipe Formulationswill enable you to make a estimation of the alcohol for your home brew Using Original Gravity [OG] and Final Gravity [FG] readings to find these you will need to use a refractometer or hydrometer To increase ABV in beers and wine during fermentation is a matter of adding more brewing fermentables effective OG 1149 with sugar additions 1.1kg in 20L (adds 21 gravity points) final Brix 17.5% gives corrected FG 1026; ABV 15.2% 2) from Hydrometer readings (temperature corrected) initial OG 1134 effective OG 1155 with sugar additions (+21 gravity points) FG 1011 ABV 18.9% 3) from final refractometer and Hydrometer readings final Brix 17.5% FG .
ABV Calculator Terminology. ABV – Alcohol By Volume; The percentage of alcohol by volume in your finished beer. SG – Specific Gravity; Technically, this is the measure of a liquid’s density when compared to pure water. When used in the context of brewing, we are generally referring to the amount of sugars present in the wort.Enter Original Gravity (OG): Enter Final Gravity (FG): Calculate Original Extract (OE): . Refractometer Calculator. Convert a temperature-corrected refractometer reading from Brix/Plato to specific gravity.
