Alcohol percentage in the wine I made

[pkirtani]

Is there any way to measure ABV in the wine I made. I did not measure SG at the start.

The only gizmo I have seen is call a vinometer. It's a $11 glass pipette.

Here is a YouTube of it in action. Not sure how accurate it is, but I'm assume it's close.

You can send a sample to a lab.

Country wines are easier to estimate because most table fruits have a starting gravity of about 1.050 (+/-) per gallon of juice and added sugar will increase gravity of the juice by 40 points per pound in each gallon.

Thanks for the information. I brought the vinometer. it measured my pear wine to have 11% ABV which is in the fruit wine range I guess.

Another way of measuring alcohol content is to measure the final SG and also take a reading from a sugar refractometer (usually available for around $30). It uses the fact that the refractive index of a liquid is influenced by the amount of sugar and alcohol present. The method was developed by makers of Port. The results can then be fed into the Home Wine Program to calculate the amount of alcohol and unfermented soluble solids. The program is available free from homewineprogram.com.
