Yeast Nutrients

Postby Hilltop » Mon Apr 23, 2018 9:15 pm

Can someone tell me exactly what is in brew shop yeast nutrients? I never have trouble with grain, but recently I had a sugar wash stall. Those brew shop yeast nutrients fired it back up. Is this brew shop stuff natural or manmade chemicals? I've used Dap before and fertilizer just wondering what this stuff is and how it's made. I see most of it is white but recently while surfing the web I saw some reddish colored yeast nutrient. I'm not a fan of tomato paste and do like the simplicity of adding these yeast nutrients but like to know what I'm using and the bags never contain any info other than yeast nutrient add this much! lol!

Admin I was dealing with a sugar wash is why I posted it here, if you feel this should be in the yeast section please move it with my apologies.

Fermaid o is organic (I use)
fermaid k isn't (I don't use)
Boiling bread yeast with a good pinch of Epsom salt will make a great nutrient, let me clarify...1 lbs of yeast, 1 quart h20, 1 tsp Epsom salt

Boil water with es, once at a boil add yeast and cut down the heat to a simmer. Continue to simmer for 15 minutes or boil down to reduce water volume.

Put in a mason jar and refrigerate.

Note☆ it's easier to measure if reduced to a paste.

1lb? Doesn't seem cost effective or time saving to me as the nutrients are cheap. That's a lot of bread yeast. I would think one could obtain the nutrients themselves cheaper but again what's in them, as at least bread yeast is natural.

I've looked around the site at various nutrients and nutrient recipes, and many of these cost more to make than the nutrients can be bought at the brew shop for, so I assume it's the ingredients in the brew shop yeast nutrients that some folks don't like that entices them to make their own nutrients. Would that be a correct assumption?

You’ll end up with plenty yeast trub slurry after a ferment clears. Boil that shti and use as nutrient.

Mostly I do grains and use zero nutrients, but boiled yeast by its self is just part of a nutrient recipe. On a sugar wash we are gonna need other things like magnesium , calcium etc, so the 5 bucks is going up.

1. Buy a bag of store bought yeast nutrient
2. Make my own

If I buy something, at best, I'll learn how to use it.
If I make it, I'll learn much more.

On a side note
I can make yeast nutrients with local ingredients, cheaper than I can order it.

Yes... it's Diammonium Phosphate (DAP) and food grade Urea.
It provides phosphate and nitrogen to the wash for the yeast to stimulate rapid, strong growth.
If you wanted to make it, for use in the hobby, you could use the urea sold in garden centers. However it's cheap enough from the HB stores...why bother?

Fermaid o is 15 bucks for a very few oz. I use this in my meads/melomel
Bread yeast at this price is great nutrients and I know what is in it :thumbup:

Urea is linked to ethyl carbonate formation (like for real, regardless of ones belief in what happens to EC during distillation or if you care to worry about it).
Excess of ammonia based nitrogen is linked to various problems from poisonous blue distillate to simple ph problems.
Dead yeast is free after your first ferment and does not have the problems of urea or ammonia. However I believe both urea and ammonia salts are fine at the correct dosage, but I dont personally think they are worth the cost or the risk.

Wheat germ is the best nutrient I've ever used for a sugar wash and using a bunch rather than a pinch of magnesium sulfate was never an issue in the wash, but with magnesium, calcium should always be present. Blow the krausen out barrel in rite conditions.

I cant imagine what would happen if adding some B vitamins and maybe some organic nitrogen along with the prepared wheat germ (crock potted/ boil't)

Folks overlook baby'n your yeast imo.... yeast bomb/starter with ideal pH'd/nuted starter water, ideal temps for yeast variety. No shocking, they are fragile as a poppy seedlings.

never handled poppy seeds myself!

1lb bread yeast
2 tsp lemon juice
1 tsp Epsom salt
1 quart of water

Boil and reduce to a paste, one tsp per 5 gal of wash. Haven't had one stall since using this.

Not all washes need nutes but for sugars washes it's not failed me.

Now this recipe looks more cost effective to make thanks.

For a 10 gallon ferment

Bring a quart of water to boil, turn the burner to low and add a 1/4 cup bakers yeast.
Prepare for drama when it trys to boil over. When it quits trying to make a mess, it's cooked long enough. 5-10 minutes

Add a pinch of epsom salts and aprox 1-2 tsp (3 - 6 gr) DAP
Throw in a couple one a day vitamins if you got them.
Adding a handful of crushed oyster shell with ground coral to the fermenter will supply minerals and nutrients
And help with pH control

Or plan B
Boil a 1/4 cup yeast and at least a cup of cereal.
The oyster shell is still beneficial

TIL: Fermaid O is not only a source of organic (carbon-based) nitrogen, but is actually a certified organic product per OMRI:
http://www.scottlab.com/product-106.aspx ... it's 2x the organic! :crazy: :D

That said, it doesn't appear that Fermaid O has the vitamin B complex that Fermaid K does, nor the magnesium salts. I'm not sure why Scott/Lallemand doesn't make a Fermaid K with carbon-based nitrogen sources but all the other goodies :?:

I have been really considering using worm castings in my in sugar washes for more nitrogen and plenty of other nutrients. It does wonders for the towering tomato plants. Be cheap shine nutrients for someone with a worm compost bin feeding the worms only organic materials. 8)

Commercial castings are a dollar per pound or make your own for free, fully organic. It's not called black gold for nothing. :shh:

Been using food grade potassium hydroxide for the pH control (after acidic sugar invert or when Uncle Jesse gets too sour) yeasts seem to be loving that potassium boost. Goose Eye, them ole boys prolly used regular wood ashes I 'spect?

Oyster shells with coral calcium rounded out with the crock-potted wheat germ. (saw a 50# sack of wheat germ fer $50) I'd rather have that than a 50# sack of DAP shit any day.... to the DAP Cave Robin!

Can always add some cooked, crimped corn for nutrients, corn has a bunch of magnesium among other nutrients. $7 for 50# with farmers exemption if you have chickens. :thumbup:

I use much more magnesium sulfate (Epsom salts) than I've ever seen anyone here suggest, don't be afraid to double or triple the amounts of MgSO4 7H2O that ya been using.

To each their own, you'll notice when yer doing it rite. Ya can't really add a bunch of Epsom salts if you NEGLECT the rest of the nutrients, they work together in harmony to produce the best batch of likker you can get from sugar washes.

Ya can't ever go wrong with Lallemand Superstart yeast for sugar washes, pre-start the yeast to use less... helping to preserve your investment in one of the best sugar-swallow'n yeasties around imo.


ShineOn, I said "poppy seedlings" if you try to transplant a poppy seedling, it is quite the endeavor, they are super fragile and this is how I view yeast. People are killing untold numbers of yeast cells by not realize'n their delicate nature or just not caring.

In working with plants, many folks over-plant seeds so they can pick the strongest sprouts (seedlings) to plant in their gardens, this doesn't happen with yeast, they must be babied from the start to the finish and more so when using bakers yeast. It's the reason why yeast starters and yeast bombs work so well.
