Dry enzyme

[Kronic]

Will adding this affect the hydrometer reading at the end of the brew?

 

[treefiddy]

The hydrometer reading will be different yes. It will read lower, because the enzyme will help lower the FG of the brew, resulting in a higher alcohol content with less residual sugar.

If you're asking the the reading will be false then the answer is no.

 

[Rodolphe01]

Yes... The hydro reading will be lower as the enzyme makes the wort more fermentable (i.e. drier).

Had -0.001 once when I used fungal amalayse, got the fella i worked with all stressed!

Never used it myself, can you stop it where you want it? Cold condition or filter it out?

Hmmmm, might have to do a bit of reading up

Cheers how much lower should it b roughly???Was a 23lt batch

Negative density. Your should consult your friendly local physicist.

The interesting thing is, a reading of 1.000 doesn't mean there is no sugar left in the liquid.
Alcohol has a density less than that of water, and in a 5% abw beer a hydro reading of 1.000 means you have roughly 2.6 g of sugar in 100 g of beer.

Kronic, I don't think anyone can safely say. Once you get the same reading over 3 consecutive days it's probably done.

Copy that thanks for the info

Per Treefiddy, check your grav's over a few days. We never noticed any change in ferment time, just that it went very very low on SG....
