MISCO Digital Handheld Refractometer

Refractometer for Testing Wine, Grapes, and Must

“The MISCO Digital Refractometer is unequaled with regard to precision and ruggedness in the vineyard and winery.”

Simply and accurately test the sugar content of grapes and grape must during winemaking. The MISCO Digital Refractometer is unequaled with regard to precision and ruggedness in the vineyard and winery.

For more than 100 years, refractometers have proven to be essential tools for the vineyard manager or winemaker. Refractometers have proven valuable for measuring the maturity and sugar content of grapes in the vineyard, the concentration of must before fermentation, for predicting final alcohol concentration, for monitoring fermentation, and as a gauge for determining the final alcohol content and residual solids in the finished wine.

Wine (4)

Hi, I just bought the Palm Abbe refractometer with 5 scales from you. I have tried it at our office but I cannot get it come to the right results. We are only going to measure total sugar content and alcohol in wines (finished wines). I have calibrated it with distilled water and it seems to measure water to 0.0 every time which is ok. As soon as i measure alcohol in red wine it always shows too high digits – up to 18-20% ABV and the sugar is always too high. What may the problem be in this case?

The problem is that you cannot directly measure the alcohol content in finished wine using a refractometer. Once fermentation begins ethanol and the residual sugar interfere with each other and prevent an accurate reading of either sugar content or alcohol content. The best method for determining the alcohol content in the wine is distillation. There are also some good methods of estimating alcohol and sugar content during fermentation and later in the finished wine. For more information, download a copy of our free guide, “Using Refractometers to Increase the Efficiency of Vineyard Management and Winemaking “Using Refractometers to Increase the Efficiency of Vineyard Management and Winemaking.”

We are a small winery on premise in Michigan and we make our wines from Must and kits only, we don’t crush the grapes. Is there a refractometer you could recommend for our purposes which could tell us actual specific gravity and Actual Alcohol readings of finished wine?

A refractometer is very useful at nearly all stages of wine production. It can be used to help assess the ripeness of grapes before harvest, predict alcohol content from the must, measure the sugar content of must, monitor the fermentation process, and determine the alcohol by volume (ABV) of the finished wine. A refractometer with the Brix scale is the best method of determining the sugar concentration of the grapes and must. Scales are available that can predict the alcohol content of the finished wine based on must measurements. Once fermentation begins ethanol will interfere with sugar readings and you will not be able to take direct readings of either alcohol content or sugar content, without using special techniques. Once the wine is finished, the same refractometer, with an ethanol scale, can be used to measure the distillate of the wine to accurately determine alcohol content.

I am interested in the VIN06 refractometer for the determination of alcohol in fortified wines. What is the process for determining the alcohol – it appears you have to distil the wine before measuring it with the refractometer. How would I do this?

You cannot directly measure the alcohol content in a finished wine with a refractometer. However, you can distil the wine and then use the alcohol scale on the Palm Abbe digital refractometer to measure the ethanol content of the distillate. More information can be found in our technical bulletin  “Using Refractometers to Increase the Efficiency of Vineyard Management and Winemaking.

How accurate is your refractometer when alcohol is present? Can I measure R.S. [residual sugar] in wine? thanks

Alcohol and sugar interferes with each other when measuring finished wine with a refractometer. You cannot measure the alcohol content in a finished wine directly using a refractometer, nor can you directly measure the residual sugar content. There are however, a couple of tricks that you can use to determine alcohol content and residual sugar content using a refractometer. These methods and more are discussed in detail in our technical bulletin, “Using Refractometers to Increase the Efficiency of Vineyard Management and Winemaking.
