I am currently doing an assignment at school that involves using different means of measuring the alcohol conc. of several different types of wine. We are thinking of using the methods of, titration, ebulliometry and using a hydrometer, but is it even possible to use a hydrometer to find alcohol conc.? Because everywhere I have read on the Internet says that it needs to be measured before you add yeast and then after.

Is there any other methods that you can suggest that are quick, easy and effective?

There is some density method that we were thinking but opted out of that one because we have limited time.

Anyone know if we can use a hydrometer?

Thanks in advance.
