This is a scientific method of measuring alcoholic strength in wines, etc. I just don't know what it is called in English.

Hydrometry
Explanation:
From http://www.monashscientific.com.au/Hydrometry.htm

Hydrometry (Hydro - water, metry/meter - measure) use the principles of buoyancy or flotation to measure liquid densities.
The simplest device used to measure the degree of flotation is a hydrometer.
There are many different hydrometer designs with varying ranges and calibration units, depending on what is being measured.
Specific gravity (SG) is one of the base hydrometry units used for relative density.
In most cases this is relative to the density of water, water therefore having a specific gravity of one (1).
Alcohol has a lower density then water (Ethanol - p = 0.789 kg/m3 @ 20oC, water - p = 1.000kg/m3 @ 4oC) and hence will reduce the density of water and will have a SG (specific gravity) reading below 1.

Thanks Kathy T. This description sounds like what I've heard about the method so far. While grammatically speaking I think mnlucht has a point, I feel it is more fair to select your answer. Thanks a lot!

neutral  KathyT: I don't think this is related to alcohol measurement. Add "alcohol" to your search link and the returned hits mention water (stream) velocity and, ummmm, turtle poo.

  -> Yes. You are right. I wanted to focus onto method using float because hydrometry has many meanings. Anyway, float method is not used for alcohol context.
