Re: hydrometer and kombucha

[Guest guest]

I think you answered your own question. If you think that there is too much

sugars reduce the amounts of sugars.

Why , if I may ask are you testing the specific gravity of Kombucha? Im just

curious.

Hi

Teresita here.

I don't post much but I had to address this question. Hydrometers don't

specifically measure sugar. They measure specific gravity (the density of your

liquid). That is, the ratio of the density of the liquid to the density of

water. They can be used to measure sugar or salt or any other dissolved solid as

long as you know the rate at which your solid changes the density of your

liquid.

In low density liquids such as alcohol, the hydrometer will sink deeper, and in

high-density liquids such as brine, milk, and ACIDS (kombucha) it will not sink

so far.

Unless your kombucha becomes water, you'll never have a reading of 1000. Its

measuring the density not the sugar content. In KT the buoyancy is affected by

how intense the tea mixture was, how much water has evaporated off, how much

sugar is present, how dense your bacterial load is and how strong your acid is.

If you want a reading of 1000 (which I don't know why you would want that) then

you'll have to water it down so as to make the KT almost null.

Hi ryilsi, I see you received another comment that kombucha is just probably

more dense than you think. So the high sugar content assumption may not be

correct. Perhaps you could test some GT store bought and compare?

Hi and thanks,

I could only get one brand of kombucha from a shop.

After letting the fizz out I get a reading of 1020.

On the label it says 4.4 gramms of sugar for every 100 ml.

I will let my home kombucha sit for another 2 weeks and

test it with the hydrometer.

With my fermented kefir carrot juice I got a reading

of 1010.

If there are different readings for different aged kombuchas

this would be an interesting indices for the sugar content

as far as I understand it.
