Yeast Nutrient

[smilinggilroy]

Have a question on yeast nutrient....
When I was doing kits & bits and partials, it was suggested to throw the yeast that came with the kit into the boil and use a specific yeast for the brew.
The dead yeast cells would help feed the yeast being used. Yeah, have no problem understanding that.
Was wondering what the go would be if one was to throw some bread yeast (15g.+/- aprox.) into the boil when doing AG- BIAB?
Would bakers yeast have any adverse results (flavours etc.) compared to brewers yeast in this situation?
TIA,
Cheers

No adverse effects compared to brewers yeast in this application.

Hey Ross,

Is this something you would recommend to do in your boils or not that much bang for your buck!

I'd do it rather than throw them away, but you'd be much better off using a proper yeast nutrient, especially when it only costs a few cents per batch.

There are two types of yeast nutrient, ammonium diphosphate which is like a superphosphate for yeast as opposed to lawns. It looks like sugar. The other one is a mixture of trace elements and other nutrients etc and is brownish and more expensive - never used that one but thinking of getting some and trying it out in high - adjunct beers to see if it gives a better fermentation.

Using dead yeast as a nutrient is something that our brothers in the water and essence purifying hobby do all the time, they get "yeast hulls" which is just dead yeast I suppose. However they often need nutrients in their craft because of their use of a lot of cheap ingredients like sugar and starches which contribute little or no nutrients to the wash when they ferment it. However as Ross says, for beer a dedicated YN is only going to cost cents per brew.

Ahhh yes......one in every crowd.

The main reason I was contemplating such is that I have surplus of bakers yeast at the moment,
some of it reaching or passing use by date. Rather use it than chuck it.

G'Day Ross -
You've got yeast nutrient here http://www.craftbrewer.com.au/shop/details.asp?PID=951

how much would you typically use per batch?

Is there areccommended g/L usage rate?
a teaspoon to the boil?
a pinch at pitching?

 

[raven19]

1/2 a teaspoon in a 20-ish L batch. At least thats what I have been using of late.

Edit - and throw it into the boil with 15 mins to go give or take. I add it when I throw in the whirfloc.

 

[Rodolphe01]

My bag of nutrient says 1 teaspoon per 23L batch in last mins of boil.

 

[JestersDarts]

cool thanks guys.

Or if u forget to add to the boil (Like I quite often do) just add boiling water to nutrient and leave until it cools then pitch it in.

I'll use excess yeast if I haven't got nutrient in stock.
