.8 is about pure alcohol, so no way is that close.

20% alcohol is .976 <---But even that is alcohol + water with no residuals whatsoever.

Here's what I was looking at: http://www.henriettesherbal.com/ecle...1/alcohol.html

And: http://www.barnonedrinks.com/tips/re...gravities.html <----Notice SoCo is .97

I'm sure it is! I actually wasn't directing the "never under .990 to you", I was just pointing out that it wasn't possible to do it. Under 1.000 is very common for wine and cider and mead- indeed, it's expected. Under .990 isn't possible, though.

And I hate to sound nitpicky, but your readings AREN'T off my .4. There is a missing number- you're off by .04. That is really important, even though it sounds like it isn't. A reading off by .04 can just be easily corrected by adjusting for the calibration.

You initially said your mead was 0.79, and that's what I said was not possible. Again, a missing number- I'm sure you meant .979, which corrected to .994. That of course is possible, and it might go even lower, to .990.

0.940, though, is really not possible.

Hmm.

Tap water at 59.7 F measured 0.850.

My mead at 61.4 F measured at something like 0.790. Compensated for the incorrect hydrometer 0.790 + 0.150 is 0.940.

So obviously that is wrong because I've had a glass and I'm not falling down yet.

Does the 0.3 degrees and the 0.4 degrees F change the hydrometer reading very much? Could that be where I'm getting an incorrect reading?

Well, do you have a picture of your hydrometer? I don't know of any scale that even goes below .990. Maybe that's why I'm confused. No, even 5 degrees doesn't affect the SG that much.

ok, here's a picture of a hydrometer like mine:



Is yours like that? Of course, there are lines between .990 and 1.000, so that I can read it at .990, .992, .994, etc. Mine goes from .990 to 1.180 ish.

Mine is just like that. It ends at 0.980 The readings I have were measured with a string. The cider was easy to estimate and the mead I measured down to the centimeter or so. I totally could have miss measured though, the mead is apparently strong.

I just measured some old fashioned soft cider I have and with my hydrometer correction it's at 1.190. Seems right.

But.............if it only goes as low as .980, (should be .990) how are you getting readings of .790? That doesn't make any sense to me.

It ends at .990 but has extra lines above it to measure .988, .986, .984...

I got 0.790 by measuring with a string the length between 0.990 and the top of the mead, then used the labeled part of the hydrometer to see what the string's length represented.

Aha! Thanks for explaining this to me! I was trying to figure it out and just couldn't.

How about warming the sample up to 70* or so in order to not need any temp compensation? Also, some of the cheaper hydrometers just have that paper slid up inside them. (well, actually all I have seen) Is it possible that maybe the paper slid a little?

Perhaps the poster could take a photo of the hydrometer sitting in water and post the picture.
