Wine Refractometer – Wine Scales – Probable Alcohol Content in Grape Must & Actual Alcohol Content in Finished Wine – MISCO VINO5 Refractometer

Palm Abbe Digital Wine-Alcohol Refractometer

Measure Probable Alcohol Content in Grape Must & Actual Alcohol Content in Finished Wine

The MISCO Palm Abbe Digital Wine-Alcohol Refractometer is engineered specifically for testing the potential alcohol content of grape must, as well as the actual Alcohol by Volume in the finished wine. Measurements are made with precision comparable to mid-range bench-top refractometers costing thousands of dollars more. This is a tool that the professional winemaker simply can’t afford to be without.

The determination of the Mass Fraction (% Mass) of grape must is clearly one of the most important measurements to a winemaker. The Mass Fraction of saccharose is the ratio of pure sucrose in a grape must to the total mass of the solution. The Palm Abbe Digital Wine/Alcohol Refractometer can quickly and accurately display % Mass to 0.1% and actual sugar content in grams/liter.

It is often advantageous for the vintner to estimate the potential alcohol content of a given grape must prior to fermenting. With a sample of only one or two drops of grape-must, the Palm Abbe Wine/Alcohol Refractometer can quickly and accurately measure the predicted actual alcohol content in accordance with established international standards.

The actual Alcohol by Volume of a particular finished wine may also be established following a distillation method recognized by international bodies. After distilling a small volume of wine, the ethanol distillate is measured on the Palm Abbe Digital Wine/Alcohol Refractometer and the actual alcoholic strength (percent by volume) or specific gravity is displayed. (NOTE: It is impossible to measure the alcohol content of wine by directly measuring finished wine on a refractometer. The wine must first be distilled and then the distillate is tested on the alcohol scale. Please see our wine guide for more details).

Protection against inaccurate readings due to temperature differences, a major concern in refractive index measurement, is assured with nonlinear temperature compensation specific to grape juices. Temperature compensation is automatic for fluids read between 0 and 50 °C (+32 to 122 °F).

The stainless-steel sample well requires only a couple of drops of fluid to take measurements. A simple, user-friendly interface consists of two buttons: one to take readings and the other to step through various menu options. A large, dual-line, multilingual LCD display is easily read, even in dim light. Prompts and measurements may be selectively displayed in English, Spanish, French, German, or Russian.

Special models are available with scales for various international units of measure including Refractive Index, Specific Gravity @ 20 ‘C, Specific Gravity @ 17.5 ‘C, Density (kg/L), Plato, Baume, Oechsle, Klosterneuburger Mostwaage (KMW), and the actual Sugar Content in grams per liter or in grams per kilogram. Scales are also available for measuring the Potential Alcohol of grape must and Actual Alcohol percent by volume of finished wine.

With the Palm Abbe PA203X, you have the flexibility to mix and match up to five different scales of your choosing, giving you the ability to create truly custom wine-testing instruments.
