So there I was, making my third batch of wine, finally from fresh grapes this time. Taking my measurements, and right there it is on my hydrometer: 60 degrees fareignheit. After just a lil digging I confirm what I figured: I'm supposed to do my testing at 60 degrees.

Well, I make wine inside my house, in Texas, after harvest...72-73 degrees.

Is this a significant problem?
 
Not really, either use a conversion chart or just measure every time at 72-74. After all, ABV is only a ratio of starting SG to finishing SG. Who cares if both measurements are off by the same amount, as long as it is the same amount.
 
OR . . . Measure a sample of room temperature water (I usually have a gallon of distilled water sitting around). That offset will be your correction factor for the wine must measurement.

When you do the conversion - you'll realize the differnce is very very small.

Here's an online calculator and by the way I just ran a check on it:

Calibrated for 60 degrees F
Actual Temp = 73 Degrees F
If the Reading is 1.020 - adjusted reading would be........................ 1.021
If the reading was 1.100 - the adjusted reading would be ------------1.001
If the reading was .990 - the adjusted reading would be ...................991

Not much at all. I wouldn't worry about that for home wine making at all.
