Howdy Guys,
Long time no see. I have been brewing despite not posting anything the past errr little while but I have been reading what's going on.

Anyway here's my question.

I've got a Hydrometer as we all should and I've got the flask type thing which goes with it, now the problem is how can you get an accurate reading? I often find it gets stuck on the sides and doesn't give a very accurate reading. I have been known to play around for 5 - 10 minutes to try and get it right.

I was just thinking about this as I was just checking this weeks brew (Munton's Mexican Cerveza) which only came in last week at my local HBS.

Any thoughts or suggestions on making this rather frustrating task easier?

I have the same probs, I usally get around this by giving the hydrometer a gentle twist as I'm releasing it into the test jar, and also ensuring the flask is vertical. My flask is a plastic tube forced into a moulded plastic base. It is almost, but not quite vertical.

using these methods, I can usally get an accurate reading pretty quickly.
That's one thing I haven't tried (gentle twist) I have tried many other ways but not this one, I shall give it a go and see what happens.

Surely there must be a digital hydrometer out there somewhere?
For verticality, don't put the sample tube down, but hold it with 2 fingers near the top and let graviyy give you true vertical. A spin, as Moray suggests, will dislodge any bubbles causing the hydrometer to float. I find it best to leave the sample for a while before measuring. When measuring wort, it is already still and the first measurement is quite accurate. When measuring a fermenting brew, I'll let the bubbles and head settle/disperse before measuring. You can shake it with your thumb on the top of the tester (without the hydrometer in of course) to help get the CO2 out.
