Thanks Janis...I learn something everyday here. I didn't realize there was instructions for this on the homebrewopedia.

And it says to read from the bottom of the meniscus.

It think it is more important to have consistent hydrometer readings than it is to have precise readings. After all you want repeatability. Precise readings are nice to have if you want to exchange that data with other home brewers.

I agree.  Precise (consistant) readings are good for repeatability.  Precision allows one to track changes despite inaccuracy.  However, accuracy is needed to exchange meaningful data with other homebrewers.

As a system operator I sometimes have to track process trends using precise online monitors, whose accuracy is out of calibration. 
There is only one success: to be able to spend your life in your own way.

I like to keep my hydrometer and thermometer together as I have forgotten to measure the temp of the wort prior to reading the hydrometer and the temp is required to correct the SG reading.

Hi Ron,
No worries, glad to help. 

Actually, I thought there was a video demonstration on the AHA web site, but not yet.  I believe we're asking for volunteers to make videos of brewing procedures like this that we can post on our Videos page (http://www.homebrewersassociation.org/pages/community/videos).  Check out the call for Volunteers (http://www.homebrewersassociation.org/pages/membership/volunteer).

Cheers,
