Yeast nutrient in beer wort?

[Galena]

I have some Tronozymol which is labelled as a wine yeast nutrient and just wondering if anyone uses yeast nutrient in beer brewing and Tronozymol specifically.

1) Who adds nutrient to the wort?
2) Should I try some Tronozymol in a reduced dosage for 23L beer wort?

Looking at the info for Tronozymol you'd be using 25g for 25 litres of wort. Seems like quite a lot, but I don't know if you can have too much nutrient.

A better bet for the future is this from the Malt Miller. 1.3g in 25 litres.

Hopefully someone else will be along soon who can say if it's possible to have too much nutrient.

Yes I agree that would be a better choice, I bought the Tronozymol (sounds like a sedative) not knowing what I was getting, I was thinking of using a bit less than the packet in a 26L boil, maybe 2 teaspoons dissolved in water and added at 10 mins?

Usually an all malt wort will provide everything a healthy number of yeast cells need. However, many of us harvest and store yeast so there are times when yeast nutrient can help towards a healthy fermentation. The nutrient I use is the White labs one linked to MM.

So would you use it with an extract kit do you think? With supplied yeast West Coast BRY 97

No, unless the yeast was very much out of date. In that case I would probably substitute an in date pack.

When I skim read the Yeast book in the series of single ingredient tomes, A couple of years ago, it suggested zinc may be the only trace element which might be low.
A couple of years ago, it suggested zinc may be The only potential deficiency.
I also wondered whether relatively rapid fermentation with higher gravity beers might put extra demands on yeast replication and therefore nutrients?
Although I can’t find the reference, old spent yeast might it provide all the additional nutrients necessary. I have frozen some of this excess yeast in ice cube trays. For a couple of high gravity brews recently, I have added a couple of these cubes near the end of the boil.
Is this nonsense, or reasonable common sense that won’t do any harm and may even do some good??

One of the MM nutrients is old yeast I think. But perhaps not.

Very pricey, though.
