- For measuring sugar and determining potential alcohol content - an areometer useful for wine settings and beer wort. Range: 0-30°Blg.
- Shatterproof, convenient test tube - the plastic cylinder for liquid has a convenient, flat bottom and will never break, which is an advantage over its equivalents made of glass.
- The ranges of concentrations recommended are marked with colours - the areometer scale features colour-marked ranged of sugar concentrations appropriate for a given stage of fermentation.
- Measurement test tube with a closure - the test tube features a closure that prevents the areometer for sliding out when carried or stored.
- Easy measuring - the device is extremely easy to use. The measurement is carried out directly.
- Thermometer in the centre of the areometer - thanks to practically direct contact with the wall of the areometer (tip of the capillary), it measures the temperature of the liquid without falsification.
Vinometer - a sugar meter for wine is a device required for determining quickly and accurately how much sugar is in a winemaking batch or beer wort. Vinometer is an areometer scaled in Balling degrees (°Blg) - 1°Blg corresponds approximately to 10 g of sugar in 1 L of juice (must). Thanks to its two scales, you can also plan the strength of your wine with its help.
The test tube in which the measurement is taken is made of plastic, so unlike its glass counterparts it is unbreakable.
For ease of reference, the scale is colour-coded to show the recommended starting and ending sugar concentration ranges for must and wort - so you don't need any additional calculations or tables:
- maroon area (22 - 25 °Blg) - initial concentration, dessert (sweet) wine
- yellow area (15 - 22 °Bg) - initial concentration, table wine (dry)
- amber area (9 - 11 °Bg) - initial concentration, beer
- green area (0 - 2 °Bg) - final concentration, beer
- red area (-2 - 0 °Bg) - final concentration, wine
It is very easy to use the vinometer. It is enough to place the areometer in the test tube and full it with such an amount of liquid that the floater floats freely. The result is read from the scale on the basis of the upper meniscus.
Since the devices are calibrated at 20°C, it is recommended to take the reading at the same temperature, which is facilitated by the thermometer placed in the wine meter. Since the liquid changes its concentration (molecules expand and contract) under the influence of temperature, it is the measurement taken at 20°C that will be the most reliable and precise.
How to use:
In order to take the measurement, place the areometer in the test tube and pour in the liquid without gas bubbles and solid particles. The amount of liquid should be such that the floater in the test tube floats freely and does not touch the container walls.
The sugar concentration is read according to the upper meniscus of the liquid.
After making the measurement, dispose of the liquid - do not drink it.
Wine strength planning:
1°Blg is equivalent to approximately 10 g of sugar in 1 L of must. Adding 1 kg of sugar increases the volume of must by 0.6 L, before the fermentation is started, the sugar level in must should not exceed 22°Blg!
Let us assume that the meter reading was 16°Blg. Must with such sugar content enables obtaining wine with alcohol content of about 7.3%. In order to obtain wine with 13% alcohol content, the must should contain 260 g of sugar per litre. Thus, the sugar addition required would be 260 - 160 = 100 g/L. In order to meet the condition of not exceeding the must sugar level of 22°Blg, the sugar amount required should be added in three equal portions: the first one before starting fermentation, and the second and third ones on 7th and 12th day of fermentation, for example.
Beer wort testing:
The measurement of beer wort sugar level is carried out in the same manner as for a wine batch.
The set includes:
- plastic test tube
- test tube plug
- areometer with thermometer
Range: from 0 to 30°Blg.
