Benefits for using Nutrient Blends

  1. Speeds up alcohol fermentation and prevents stuck fermentation
  2. Removes the sulfur smell from fermenting (which is usually because of stressed yeasts).
  3.  Improves the Alcohol ABV by helping yeast finish fermenting dry.
  4.  Accelerates the fermentation rates especially for brewers of winters and Himalayan regions.
  5.  Reduces diacetyl and off-flavor notes from fermented beer and wine.
  6.  Diammonium Phosphate provides the necessary nutrients for yeast to make basic amino acids. Hence the yeast colony does not mutate and there is flavor consistency.

Key Features:

  1. Boosts Yeast Metabolism:
    • DAP provides essential nutrients, including nitrogen, vitamins, and zinc.
    • Yeast assimilates these nutrients, allowing it to multiply and ferment efficiently.
  2. Prevents Stuck Fermentation:
    • Yeast Assimilable Nitrogen (YAN) is crucial for yeast health. (American limit is 0.988gm/liter)
    • DAP ensures that your yeast doesn’t get stuck during fermentation.
  3. Stress Relief for Yeast:
    • High sugar levels, low oxygen, and other stressors can harm yeast.
    • DAP acts as a multivitamin, helping yeast thrive even in challenging conditions.

Dosage Guidelines:

  • Use between 0.25g to 1g per liter of your brew. 5gm packet is sufficient for 5 liters for wine and 20 liters of beer.
  • Adjust based on sugar/alcohol levels and oxygen availability.
  • For grain mash, add 0.25g per liter along with your yeast starter.

Benefits of Using Yeast Nutrient:

  • Improved Alcohol Content: Yeast finishes fermenting dry, resulting in higher ABV.
  • Consistent Flavors: Strong yeast cultures mean flavor consistency.
  • Reduced Off-Flavors: Say goodbye to unwanted notes in your beer or wine.
  • Faster Fermentation: Especially beneficial in colder climates.

How to Use:

  1. Add it to the wort along with hops during beer wort making (0.25gm per liter) The boiling will help in dissolving and assimilation as well
  2. For wine: add 0.5-1gm of yeast nutrient per liter (higher dosage because fruits are low in nitrogen and proteins). This is to be added along with yeast (usually on second day after mold killing campden powder is ventilated to the air)
  3. for yeast Harvesting, and yeast culture 1-2 gm per liter is added along with DME in the wort. Boiled cooled and then yeast slurry from your previous batch is added.

Sulfur (H2S) – The aroma of rotten eggs or burning matches from the beverage is a result of H2S residue. It gives the beer, smell of the LPG gas, or decomposing organic waste. It is a sign of stressed yeast. The easiest way to replicate (in your experiments) is by using bread yeast to produce ethanol (stressed yeast= high sugar, high alcohol, and no oxygen). Amateurish quest to produce the highest ABV possible of adding too much sugar in wine and malt in beers will also yield these Sulfur aromas. Using the right strain of yeast, adequate oxygenation and nutrients help in keeping the problem at bay. Winemakers and brewers use a few drops of copper sulfate to remove these unpleasant flavors. However, use it sparingly because of copper toxicity regulations in food.

One of the easiest ways to get rid of this smell is:

  1. Use proper brewer’s yeast instead of baking yeast for fermentation
  2. Fine with a few drops of copper sulfate solution.

Winemaking 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 usage of more than 1gm per liter is banned in the 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 the 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 homebrew 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 nutrients are chemicals and dead yeast extracts that have a 2-5 year shelf life. So it is completely fine to use an old yeast nutrient in your yeast starter.

If you happen to stumble upon an 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 an ice bath
  5. Wait until 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 homebrew 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.

Although Yeast Energizers are types of nutrient blends, they also contain components such as vitamin B, diammonium phosphate, tricalcium phosphate, magnesium sulfate, and yeast hulls. Yeast energizers are particularly useful to restart a Stuck Fermentation, as it allows yeast populations to increase in a batch of beer or wine which likely has been depleted of these components due to an earlier yeast population growth. The additional components included in Yeast Energizers are most effective when for high gravity fermentation (high sugar high alcohol), low-temperature lagering, excessively low pH, high ash content (molasses) and other extreme fermentation styles.

The 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 cider 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 metabisulfite) on the first day i.e. before adding yeast. This is food for the yeast and not for other bacteria and wild microorganisms. Similarly, whether you are making beer or wine, don’t add it in second or after 3 days into fermentation (unless it is a stuck ferment)

 Yeast Nutrient & Energizer will remain stable for 1 year if stored in an airtight container in a cool environment away from sunlight. Simply reseal the silver pouch and keep it in the refrigerator/freezer and you should be good to go.

Mangrove Jack’s craft brewer’s yeast sold at is in the dry form. Dry yeast is easy to store, transport, and carry. The wet yeast on the other hand needs to be chilled at all times and has a shelf life of a few weeks (as compared to almost 2 years for dry yeast). As a result for a hobby brewer and even microbrewery dry yeast is much more convenient and easy to use.

Although most manufacturers recommend that you use the yeast directly, but rehydrating the yeast is always advisable for the following reasons:

  1. When hydrated, the yeast forms spores and goes into inactive state. By hydrating it in a sugar/wort plus nutrient solution, you give it adequate time and jumpstart to become fully active again.
  2. Yeast often dies when expired, mishandled, exposed to humidity or high temperaures during transportation or storage. If you pinch it directly in the wort, it will take 24-48 hours before you can detect yeast inactivity. By hydrating the yeast, you are always 100% sure the yeast is active.
  3. Hydrated yeast have a jumpstart over any other contaminents or microbial infection. When the wort is cooled, it sometimes picks up infection from the fermenter or air. If the dry brewer’s yeast is hydrated (good yeast count) they are able to fend off infection by the mere fact that they are more in number and faster in activity.


  1. Take 5-10X of sterlized water (boil the wort or water) (50ml)
  2. If you are using water then add some priming sugar or table sugar to make a 5% solution (2.5gm or 1/2 teaspoon). DME or wort can be also used instead of sugar.
  3. (optional) add nutrients 1/4gm per 50ml.
  4. Boil and cool it to body temperature.
  5. Once the solution has cooled to 25-35 degrees celsius then add your yeast (5gm)
  6. Wait for 30 minutes to foaming to start and then add it to your beer wort or wine must.

If the foaming has not happened. Then wait for another 30 minutes. If not then the yeast is probably inactive and it might be best to use a backup sachet.

I use this a lot specially when I am creating my ginger bug from scratch for the ginger beer. This will make sure you don't have stuck fermentation. Also having in smaller packets makes it easier to store and I don't have to have too much wasted in case I don't use all of it.
