Yeast Nutrient DAP

(10 customer reviews)


Speed up fermentation by giving proper food to your real workers: Brewing yeast. Superfood for your cultures to help them grow, multiply, and produce faster without any mutations or stress.

Yeast nutrient DAP a.k.a. Di-ammonium phosphate with some vitamins, zinc, and micronutrients. Each gram of nutrients provides the ~205mg of YAN needed for the yeast. (yeast assimilable nitrogen) needed for it to multiply and prevent stuck fermentation. DAP is multivitamins for the yeast to create strong cultures. Yeast nutrients can also be used as yeast energizers as well during stuck fermentation. It is good to stop the yeast from mutilating in a stressed environment high sugar, low pH, low temperature, zero oxygen, etc.

Dosage for Yeast Nutrient DAP: Use between 0.25gm to 1gm per liter. Do note that higher sugar (or alcohol levels) and low O2 levels stress the yeast. So higher is your Brix/ Degree Plato values, the more nutrients you need to add. If you are step-feeding sugar in your wines, please add nutrients also in each step.

For grain mash 0.25gm per liter added along with yeast starter gives the best results.

Also recommended to be used along with stir plates if you are washing/propagating yeasts and other wild cultures. Agar & petri-dish can be obtained from the medical labs.

TTB (American Alcohol & Tobacco Tax & Trade Bureau) limits yeast nutrients to 0.968 g/l, which is enough to give the YAN (yeast assimilable nitrogen) to give 15% v/v strength of ethanol.


Wine making is like any fermentation or curd making. If you add too much jaman (curd starter culture), then your milk will turn into curd faster, but there will be no other perceivable change in your final product. However, if you don’t add enough starter culture, then the milk will spoil. Similarly, wines require a dosage of yeast. If the active yeast cell count is too low, you will be prone to spoilage. However, adding too much yeast will only lead to faster fermentation and no other change. The yeast will finish their job fast, settle at the bottom and will be raked off.

Adding too much yeast nutrients or DAP is serious. It is a chemical and use of more than 1gm per liter is banned in USA.

Typically 4-12 days but it depends on a lot of factors:

  1. Fermentation temperature. Higher the temperature faster the fermentation is (but beware of the off-flavors produced in yeast fermented at above 25 degrees Celsius)
  2. Yeast dosage. although 1gm/liter is recommended. Increasing it to 3gm/liter can produce wine in 2-3 days (50% reduction in time)
  3. Availability of yeast nutrients. Grape and fruit juices don’t have enough natural proteins for yeast to multiply fast. Adding 0.5-1gm per liter of yeast nutrient is sufficient to establish a healthy yeast colony and fast fermentation. Mead is notorious for being slow to ferment and produce nail polish like off-notes because of a lack of nutrients.
  4. Sugar concentration: 18-25% w/v of sugar concentration is ideal for fermenting with wine yeast. However higher the concentration, the more time it will take for the yeast to finish its job and produce ethanol.

Raisins are dried grapes. If grapes had enough ammonia, phosphorus, zinc, and vitamin Bs then we would not be adding nutrients in the first place. So short answer is that raisins are a good source of glucose and cellulose (skin). It is not a good source of nutrients. The raisins do help in improving the flavor and ABV of your homebrew, but apart from that, it has little impact on the health of your yeast colony.

Yes you can ferment home brew wine and beer without yeast nutrient as well. However it helps because of the following reasons:

  1. yeast nutrients have YAN (yeast assimilable nitrogen) which is needed to establish a healthy yeast colony. Healthy yeast = faster fermentation, lesser chances of infection (which means safer ethanol production), lesser yeast mutation (better flavor consistency).
  2. It prevents stuck fermentation
  3. Better flavor profile. Nutrients reduce the stress on yeast and prevent the off-flavor production in homebrew beer and wine

Yeast is very temperamental and goes bad very fast. In comparison yeast nutrient are chemicals and dead yeast extracts that have a 2-5 year shelf life. So it is completely ok to use an old yeast nutrient in your yeast starter.

If you happen to stumble upon a old yeast nutrient and cannot buy a replacement, then don’t worry.

  1. Take 100ml of water
  2. Add 5gm of sugar
  3. Add 5 gm of yeast nutrient (old)
  4. Boil the three for 10 minutes and cool it in a ice bath
  5. Wait for the temperature reaches 30 degrees
  6. Sprinkle 5gm of dry yeast, stir gently and wait for 15-60 minutes
  7. Whoa! you have a yeast starter for a 10 liter batch.

Yes, they need lots of yeast nutrients (0.5-1gm per liter compared to 0.25gm per liter in case of home brew beer). The reason is that honey and apple/fruit juice don’t have enough proteins and nitrogen. With a low YAN (simply put nitrogen that yeast can use) the fermentation tends to get stuck and is prone to infection. To compensate that we use 2-4 times more yeast nutrient. This helps establish a healthy yeast colony, prevent infection, stuck fermentation and off-flavors

Yeast is the single-celled microorganisms that are responsible for fermenting sugar (maltose, glucose, fructose, sucrose, etc.) to ethanol. In the absence of oxygen, these yeasts do the transformation which converts your grain/fruit into a beverage. Yeast nutrients, on the other hand, are food for the yeast. on their own nutrients achieve nothing more than making a comfortable home for the yeast to function at its best capacity. Yeast energizer, on the other hand, is an SOS remedy needed to recover from stuck fermentation or incomplete fermentation or excessively low-temperature fermentation which can make yeast sluggish.

Best time to add yeast nutrients is in the starter culture when you are hydrating the yeast. Beer brewers also add yeast nutrients during the last 10 minutes of the boil so that the ingredient gets sterilized. Wine and coder makers typically add it during step feeding (along with sugar in 2-3 stages during the initial days of fermentation). What you should never do is add the yeast nutrient along with Camden (potassium meta bi sulphite) on the first day i.e. before adding yeast. This is a food for the yeast and not for other bacteria and wild micro organisms. Similarly weather you are making beer or wine, don’t add it in secondary or after 3 days into fermentation (unless it is a stuck ferment)

    Top quality. Always needed a nutrient for better fermentation. This or yeast energizer does the work. Gona do two different batches with nutrient and energizer and let’s see what’s best for my liking.

      We are glad you liked the quality of the yeast nutrients which is utmost to us. We have 50 and 100 gm bulk packs which would be more economical.


    Can it be used with beer yeast for better result?
