Gravity reading problem

Postby Hunter7922 » Sat Mar 25, 2017 5:48 am

Newbie question on hydrometer gravity reading.
ok, well I've read a lot of New distiller reading Lounge and I think I'm defiantly getting there.

I have done about 90% of the cleaning and will run the ethanol cleaning this week end, but in the mean time I though that since Uncle Jesse's corn mash takes about a week to ferment I would start it now and finish my still cleaning and test runs.

So the Mash I made was 9 lbs cracked corn (bird seed - no preservatives), 8 lbs cane sugar, 5 gal water (2.5 gal I heated up to 180 deg to dissolve the sugar). I then waited until temp was 104 and before I added Red Star dry active yeast I took my Gravity reading.

My Hydrometer did not sink at all, why?
Temp was to high, to much sugar to corn, not enough water....

Any help would be great.

Thanks

Are you testing just the liquid? The floating corn will stop the hydrometer with UJSSM so take a sample of the sugar/water mixture and test in a test cylander. Also hydrometers are temperature specific.

Are you trying to use your tails meter or an wine/beer hydrometer?

thanks Bitters
99% of the corn was out of the my test cylinder. the liquid was very cloudy and I can only assume that's because of the sugar content.

I purchased a LD Carlson proof and tralles scale as I think this is for alcohol reading and not beer.

was it resting on the grain bed and not sinking?
With my current recipe I've got so much grain I have a tough time finding a reading spot.
Gotta take a sample out.

What you got there is beer. Proof & tralle won't work until you distill it.
You need a beer & wine hydrometer also

+1 or a refractometer. Off topic but thanks MCH just reminded me to add a link in the Glossary to the thread on how to read the hydrometer.
