Fermax & Ammonia smell?

[bryan]

<DIV =postcolor id=post-385289>Hello,

I pitched the yeast for my reisling (6 gallons)yesterday and today I added fermax yeast nutrient. I mixed 5 teaspoons with a little water and juice then put it into the juice. I was about to clean the cup I used and noticed a heavy smell of ammonia from what was left over from the mixture in the cup. This is my first time using Fermax is this a normal smell from this. Has anybody noticed this before? Oh and the cup was clean and did not have an ammonia smell before using it.

Thanks,
Bryan

Did the Fermax come with the kit??

It was not a kit. It was fresh juice. I added the fermax on the advice of the person at the wine shop. Said it would be good for yeast fermenting

Pbdist,


Fermax is a yeast nutrient and therefore a source of nitrogen. Ammonia is one of the ways that nitrogen can be contained (NH3). DAP (di-ammonium phosphate) is another and releases more nitrogen per grame than Fermax. While care must be taken when adding yeast nutrient early on (nitrogen can shock/burn new yeast cells), it should be fine.


When a YANC profile is run on a wine, there are two sources of nitrogen available for the yeast that are tested and add together for the YANC numeric value - assimilable amino nitrogen and ammonia.
