Yeast nutient questions?

(1/2) > >>

dzlater:
After attending the cider seminar at the AHA conference I want to give it another try.
The recipe says to use Fermaid-k and DAP.
I have wyeast yeast nutrient can I just use that?

kramerog:
What is in your yeast nutrient?  Going from memory, Fermaid-K has micronutrients like vitamins and trace minerals while DAP is diammonium phosphate, a source or nitrogen and phosphorous.  If your yeast nutrient has got all those things then you are good to go.  FYI, I haven't listened to the cider seminar yet, but I doubt there is something specific to cider that I'm missing.

Seems like it should work OK.
From the wyeast website:

Product:   Supplemental nutrients for propagation & brewing
Description:

A blend of vitamins, minerals, inorganic nitrogen, organic nitrogen, zinc, phosphates and other trace elements that will benefit yeast growth and complete fermentation. Additional nutrients are most valuable during yeast propagation and sluggish or stuck fermentations. Supplementing with nutrients will reduce lag time, improve viability and provide consistent attenuation rates.

Jimmy K:
Fermaid K contains nitrogen, nutrients, and yeast hulls. It's a well balanced meal. DAP is just a source of nitrogen (Fermaid K contains DAP as a nitrogen source). DAP is candy. Typically, Fermaid K is added early to make sure the yeast are healthy. DAP is added later if needed to make sure the yeast finish the fermentation job. WYeast nutrient is probably a fine sub for Fermaid K.
 
Adding nutrients can make a significant difference in the amount of sulfur yeast produce in cider. I smell mine every day. If I notice sulfur, add some nutrients and it's gone in a few hours.
