This sounds too ridiculous to be true, but I think I am using my hydrometer incorrectly.
My first batch of beer measured out to about 3.5% ABV. I know that tasting alcohol is difficult and subjective, but pretty much everyone that tried it felt like it was more in the 4-5% range. I think the problem that time was that the FG sample had CO2 in it and falsely raised the gravity reading.
The second batch of beer measured 5.5% ABV. That seemed reasonable, but again, people really felt it after a pint. This was a sweet stout with 4 lbs of blueberries added. This is when I realized that CO2 might be an issue.
Third batch went into primary yesterday. This was basically all-extract, including 3 lbs of honey and 0.5 lbs of honey malt for steeping (it's the Jim Rossi Honey Pale). I measured the OG at 70F and got 1062. The expected OG was 1058. Just for kicks, I put the sample in the fridge overnight to let it settle. This morning, I took it out of the fridge and let it warm back up to 70... And I measured 1070.
So now I know that I am doing something horribly wrong. I just don't know what! Here is the procedure I am following:
1) Take sample into sampling jar (I use the spigot attached to my bucket).
2) Wait a bit to let sample settle out and reach room temperature.
3) Gently drop in hydrometer, spin it around, and let it stop bobbing.
4) Read reading.
Using this method, I seem to consistently underestimate the ABV, and I think that my OG is reading is slightly higher than actual, and that my FG reading is even more higher than actual.
Uhh... help?
