13 best alcohol refractometers
Alcohol refractometers are specialized instruments used for measuring the concentration of alcohol in a liquid, typically in beverages like wine, beer, and spirits.These instruments are important tools for quality control and production in the alcohol industry. Here are some key points about alcohol refractometers:
Principle of Operation: Alcohol refractometers operate based on the principle of refractive index. When light passes through a liquid, its speed changes, and this change in speed is proportional to the liquid's refractive index. The refractive index of a liquid can vary with its composition, including the concentration of alcohol.
Alcohol Concentration Measurement: Alcohol refractometers are specifically designed to measure the refractive index of liquids containing alcohol. By measuring the refractive index, these instruments can determine the alcohol content of a sample.
Brix Scale: Alcohol refractometers often display results in Brix units, which is a scale commonly used in the beverage industry. Brix units are a measure of the sugar content in a liquid, and alcohol content is closely related to sugar content during the fermentation process.
Calibration: To ensure accuracy, alcohol refractometers need to be properly calibrated using a standard reference solution with a known alcohol concentration. Calibration should be performed regularly to maintain accuracy.
Temperature Compensation: Many alcohol refractometers are equipped with temperature compensation features. Alcohol content can be affected by temperature, so these instruments account for temperature variations to provide accurate readings.
Portable and Handheld: Some alcohol refractometers are portable and handheld, making them convenient for use in different locations, including wineries, breweries, and distilleries.
Hydrometer vs. Refractometer: While alcohol refractometers are useful for estimating alcohol content, they may not provide precise readings for alcoholic beverages with high sugar content. In such cases, a hydrometer, which measures the specific gravity of a liquid, may be used in conjunction with a refractometer.
Industrial and Laboratory Use: Alcohol refractometers are used both in industrial production settings and in laboratory environments to ensure the quality and consistency of alcoholic beverages.
Maintenance: Regular maintenance, such as cleaning and recalibration, is important to keep alcohol refractometers functioning accurately over time.
In summary, alcohol refractometers are valuable tools in the alcohol industry for measuring the alcohol content in various beverages. They rely on the principle of refractive index to provide estimates of alcohol concentration, helping producers maintain product quality and consistency. These instruments are essential for quality control and ensuring that alcoholic beverages meet regulatory standards.

User questions & answers
| Question: | My refractometer is impossible to calibrate... anybody else have issues or tips |
| Answer: | I used distilled water and put three drops on the prism. Close it so there is no air bubbles and right under the light it should have a blue tint to it. Just lining the Blue tint line to the 0 line. |
| Question: | does it measure brix for grape to know if it is ready to harvest for wine |
| Answer: | Yes it does. I've tested boxes of (Zinfandel) grapes from California in September that I use for wine-making and they've been in the neighborhood of 23-25 brix. I'm sure you can read about higher brix levels but that's about what I get for those grapes and this device. All you do is squeeze a drop or two onto the sloped lens, close the clear cover over so it smears, hold it up to the light and read the scale. You can try several grapes or crush a number of them together to get an average. |
| Question: | can I use this for melases ? and how to use |
| Answer: | I am assuming the by melases you mean molasses. I have not tried to measure the specific gravity (SG) of molasses but I suspect you will have trouble with pure molasses. The SG might be out of range and the dark color of molasses may make it hard to read. If the molasses is dissolved in water then yes you should be able to use the reflectometer. To use a refractometer first zero the refractometer using plan water close to the same temperature as what you are measuring. SG is dependent on temperature. Once zeroed dry the surface and put a couple of drops of what you want to measure on the refractometer and read the results. The refractometer is easier to read in bright light: sunlight or a flashlight. |
| Question: | Can i use this to test the sugar content of my homegrown fruits and vegetables |
| Answer: | Yes, you can. |

Alcohol & Brix Refractometer is primarily for winemaking. It test the sugar content (range up to 40% Brix) and alcohol concentration by volume (range up to 25%Vol) in grapes. With a few drops of grape juice on the testing prism, you will be able to know the brix and predicted alcohol level.
With RETK-80 you can:
* measure the percentage Brix of grapes or other fresh fruit
* determine the progress of crop ripening
* measure the sweetness of grape juice. Used to classify grapes
* predict the alcohol content of the wine by measuring the sweetness of the grape juice
* measure the amount of sugar present as well as alcohol concentration in grapes
* allow the winemaker to determine when a fruit is at its peak of ripeness and should be harvested

User questions & answers
| Question: | Can this give me the percentage of alcohol in a finished beer without knowing the original gravity |
| Answer: | It measures % alcohol by v/v, not specifc gravity. |
| Question: | Does this refractometer actually measure the alcohol abv of a finished wine, or just the sugar content before and after fermentation to infer a pabv |
| Answer: | You have to put a drop of the alcohol to measure. As the description says range between 0 and 80%. I found that above 70% is not that accurate any more. This is good for checking home brewing of wine or beer. |
| Question: | Can you use this device to measure sugar and alcohol level on Kombucha |
| Answer: | Hello,No batteries needed for this refractometer,it's portable when you go out.It's a tool designed based on the function of refraction. |

User questions & answers
| Question: | Can this be used to measure the alcohol content of homemade hand sanitizer |
| Answer: | Yes, this tool just measured the Specific Gravity/Brix of a liquid. If you know what the beginning SG/Brix was , and then measure the "after fermentation" SG/Brix , you can figure out what the Alcohol content is in a liquid. It will not just tell you what the Alcohol Percentage is in a wine though. You will have to know the two values and do the math |
| Question: | Will this measure alcohol content of finished beer? I'm making an "NA" and want to be sure that it's truly non-alcoholic...or at least less than |
| Answer: | As i know, this device measures the sugar content of a clear and nonalcoholic solution. It doesn't measures the alcohol content, but the alcohol potential (after fermentation) of a water and sugar solution. |
| Question: | Can I use this to check the dilution of isopropyl alcohol to make sure it’s at |
| Answer: | The liquid measurement is very easy. Place a few drops of the liquid on the optical part of the refractometer, cover the prism (the liquid will spread more easily over the prism), look throught the eyepiece against the light (focus, if necessary) and you will be able to read the result value on the scale. |
