vinometer

[appleweld]

i tested my first batch of wine with a vinometer and it said it was 15%. the hydrometer readings tell me its a 11.3%. i tested a dry vermouth labeled at 18% and the meter said it was 5%. i retested both again, and the next day as well and got the same result. is the vinometer wrong? by the way, its a pear wine. looks and tastes great for a newby i think.

appleweld; there are a few things that can throw the reading of a vinometer off.....If you use the readings from your hydrometer you will get a very good idea what alcohol is...

Beginning SG - Final SG x 136 =ABV [This will get you very close]

I have had little success with the vinometer. Admittedly I have not used it often.


When I ran a store, I did not like to sell them (even though they are inexpensive), because they are difficult to use and seem hopelessly inaccurate.


I have heard that residual sugars will cause them problems, but I found them inaccurate for dry wines.

I tried using a couple different ones and gave up. Just using SG calcs is a lot more accurate than any results I ever got with them.

And cheaper!

And cheaper!

really???? When I ran my store I sold vinometers for about $5 and hydrometers for $8. Of course, the store was in Canada and it closed in Sept 2008.

I use my vinometer for every kit. Mostly because I am horrible with math calculations.

Beginning SG - Final SG x 136 = ABV
OR
Beginning SG - Final SG divided By 7.36 = ABV

WHICH IS CORRECT

i, too, stopped trying to use the vinometer...and just use the calculation methods now

Doing a calculation on a piece of paper is cheaper than buying a vinometer that doesn't work..........

I assume that everyone already owns a hydrometer already.

And cheaper!

I just go to brewcalcs.com. It's designed primarily for beer, but it does the SG correction for temp and calculates both ABW and ABV. Even I can do it this way.

fivebk;

If you use .00736 as your dividing number, you don't move the decimal point and read as is........The two formulas will be within tenths of each other....Hope this helps....

BOTH!!! or NEITHER!!!


For example. starting sg 1.092, ending sg .992, difference is .100


diff x 136 = 13.6%
diff /7.36 = 13.587%


Personally I think these two formulae produce a %age that is slightly high. At least in comparison to the triple scale hydrometers that I have used. I prefer


diff x 133 = 13.3%


But even that's not much of a difference. They are all 13.5% within margin of error (ie my ability to read and record a hydrometer reading).

I jsut bought one and have not been able to get a reading - I thought it would be more accurate than calculating SG.......
