Method one: classic

Measurement of the strength of the drink, a hydrometer for alcohol or in people, the alcoholometer. This device is immersed in the alcohol-containing liquid, and shows the concentration of the contained alcohol. Or, more simply, the percentage of alcohol. This device has several types operating in different modes and with different liquids. For example, venomer determines not only the fortress wine beverage, but the amount of sugar in it.

Domestic wineries and hydrometers are good for home use - the first is a snapshot of the mercury scale, the second is indispensable in the measurement of small volumes. Optical alcoholometer has a high accuracy in the measurements of a multicomponent alcohol-containing liquids, whereas e-and all the above devices are only good for alcohol or water-alcohol solutions. The alcoholometer and laboratory used in the manufacture of, for measuring the amount of alcohol in various funds for household needs.

Hydrometer for alcohol is an extremely fragile device, so requires careful handling. During shaking, and some other mechanical stress, the device can give inaccurate readings, as well as the most common spirometry mercury scale, their damage may cause leakage of "liquid silver" and poisoning. immediately before use, the instrument should be cleaned from stains and other dirt, and wipe dry. Immerse the alcoholometer, preferably in the middle of the vessel with the medium to be measured, without touching its walls. For the most accurate readings of the temperature of the liquid should be 18-20 degrees. Electronic alcoholometer almost immediately give figures on mercury must wait for when the mercury will take a stable position. Then at the markings on the scale will determine the number of degrees or strength of the drink.

Method two: obvious

Each country has their own form of notation strongholds produced in her alcoholic beverages. Some, for example, believe that taste and aromatic bouquet is much brighter draws the properties of the drink, and numerical designation of a fortress does not exist. In our country regulations are less democratic: as a rule, alcoholic containers in the calculation of the weight percent of alcohol specified number of degrees, when calculating the volume of alcohol is its percentage relative to the total composition of the drink. Usually present both of these options. So to determine the strength of the drink is sufficient to study its packaging.

Method three: modern

The effectiveness of the alcoholometer alcoholic mixtures reduced to almost zero, and because the strength of the cocktails is not specified-neither in the menu nor on the glasses, we have about it can only guess based fortress cocktail components. However, to solve this problem you can use an online calculator fortress of alcoholic cocktail. Choosing the right ingredients, putting their volume, you can get the amount of alcohol ( % of volume) in the mixture.
