This is the most complete table I have found for correcting an alcohol hydrometer calibrated at 60F for any temp from 0*F to 100*F at all proofs.

From the Alcohol and Tobacco Tax and Trade Bureau so I would assume they are pretty accurate.

You may want to check to see what temp your Alcohol Hydrometer is calibrated to (it should say on the scale inside it). I was using this site http://www.stillmaker.de/correction_table.html which uses a Widder Hydrometer which are calibrated for 20*C or 68F but when I looked carefully at my Hydrometer from Brewhaus it is calibrated for 60F.

The depressing result being I have been thinking my product was just under 95% when in fact it is only about 93%.
My next run I will be using a lot more reflux to hopefully get it closer to a true 95%.

Nice! Thanks for posting.

There's an app called Brewzor for Android in the google play store that I use. It works great.

Shut up!!!! I've been thinking that would be great. Gonna get it now. Anybody else know of other apps for android? Or maybe someone can develop an app that incorporates all the calculates on the main page!

Just found distillers toolbox on play store, haven't tried it but sounds good!

Poor Wanker! That 95.6% figure you keep seeing is %ABW, alcohol by weight. I always thought it was %ABV, too. But when you convert %ABW to %ABV, it comes out to 97.2%ABV.
