Which yeast for pizza dough?

The internet is already full of information on yeast regarding their different kinds, weird names, and fermentation times.

Most certainly, you read about yeast before or at least have seen the various yeast packets at the supermarket, not knowing the difference between them. 

In this article, we are going to dive deep into how to use yeast specifically for homemade pizza.

Let’s get started!

What is Yeast?

Yeast is a living single-celled organism, a fungus. There are hundreds of yeast species, but all have something in common, and they all love sugar.

One particular species likes to eat wheat.

Like other fungi, yeast likes warm and wet places to grow. Yeast is alive, and like all living things, it has the essential functions of respiration and reproduction. 

Also, the same as for any other living organism, it can be killed, meaning your dough won’t rise if is dead.

Did you know that you can make your yeast at home? Yes, you can, but that would be for another day.

Today, we are discussing it for homemade pizza purposes.

What Kind of Yeast is Used to Make Pizza Dough?

Yeast is the driving force of your homemade pizza dough. Different yeasts produce different flavor profiles in pizza dough.

It’s is available in two forms:

  • Fresh Yeast
  • Dry Yeast

You can use either fresh or dry yeast to make homemade pizza. These two classifications have different characteristics that will determine which one to use, depending on the kind of pizza you want to make.

You can use any type of yeast to make homemade pizza. The difference will be the fermentation process or duration, and the flavor profiles each yeast brings to the table.  

fresh and dry yeast

Fresh & Dry Yeast for Pizza Dough

You can use either fresh or dry to make pizza.

Fresh Yeast for Pizza Dough

Fresh yeast, sometimes called “Cake” or “Compressed,” is not available everywhere, partly because it is highly perishable. It must always be refrigerated, and its life span is very short. 

Fresh yeast combined with good pizza flour or bread flour is the secret weapon of traditional pizzerias.  The reason why their pizza tastes so good!

Fresh Yeast

Fresh yeast is mostly used in commercial applications where they make pizza every day and they don’t have to worry about spoilage.  

Active Dry Yeast

Dry Yeast

Yeast is a single-celled fungus that exists in many forms.  It converts sugar and starch into carbon dioxide bubbles and alcohol, which makes it useful in the production of baked goods.  

In the context of pizza, it produces carbon dioxide when mixed with warm water, flour, salt, and sugar, which causes the dough to expand resulting in a soft and spongy product.

Dry Yeast for Pizza Dough

Among the dry category, you will find different sub-categories:

All the dry yeasts are from the same species: Saccharomyces cerevisiae.

The difference between them is the way it’s is manufactured or processed; the coating applied and its respective power performance.

These processes determine how soluble it is is and how fast it reacts to hydration and temperature.

Difference Between Fresh Yeast and Dry Yeast for Pizza Dough

The difference between fresh and dry is their respective water content.

Manufacturers remove the water from the yeast to keep them dormant so they can be stored for more extended periods.

For fresh yeast, manufacturers remove about 30% of the water, and about 90% of the water is removed from the dry yeasts.

These days manufacturers have developed a new process to produce yeast that doesn’t require that you activate it before using it. You no longer have to activate dry yeast. We still do it, and we will explain why later.

Pro Tip

Yeast is a living thing, so you want to treat it right. Always check the expiration date and mix it with the right temperature water, and store it properly, too. While fresh yeast should be stored in the refrigerator for up to two weeks, the freezer is the best place to store any type of dry yeast. This will put it on pause and extend its active lifespan even past its expiration date.

Common Characteristics of Fresh Yeast and Dry Yeast

The one thing they have in common is that they are predominantly dormant and can only be activated by hydration and heat.

Therefore, you should store all yeasts in the refrigerator.

When buying yeast for pizza dough, something to keep in mind is that you don’t know under which circumstances it was held in the supermarket before you purchased it.

The yeast could have been killed, or the lifespan might have been shortened due to inefficient quality control measures.

The average supermarket does not carry fresh yeast. It can only be bought at specialty stores while the dry yeast is never kept in the refrigerator section.

For this reason, we always recommend that you should activate it before using it. Doing this provides a sense of security that will save you time and money.

Because if you mix the flour with dead yeast, you will end up discarding all the flour and starting the process all over again.

Do You Need to Weigh Yeast?

It is highly recommended that you weigh it the same as you would for any other pizza dough ingredient — by weight instead of volume. If you want to be precise, you can always get a digital pocket scale that measures to the hundredth of a gram (0.01grams).

Why Do We Need to Use Yeast in Pizza Dough?

Yeast is used in pizza making to leaven the dough, or in simpler terms, rising the dough, developing the gluten, and contributing delicious yeast flavor to your pizza crust. 

Rising is the process where the yeast works its magic. It’s technically called the fermentation process.  During this time, the yeast will eat the starches in the bread flour and release carbon dioxide and alcohol, which will make the dough inflate like a balloon.

This process is essential for giving the pizza crust its delicious flavor and texture. Without it, you end up with a flat cardboard type of pizza.

Making pizza dough is a 2-step fermentation process.

Are You Still Baking Pizzas in Your Kitchen Oven?
You Might Regret It, Don’t Miss Out!

Are you up for trying something new?

Go from a soggy pizza to the perfect pizza! How? With an Ooni pizza oven.

You might be thinking, a what?

With an Ooni pizza oven, you can bake your pizza in as little as 90 seconds.

They are not only affordable but you can take them anywhere. 

Let’s check them out, you won’t be disappointed!

Rising Process

During the first fermentation process, you combine all the ingredients water mixture, flour, and salt, and let sit covered for 1 – 1 ½ hrs or until the dough doubles in size.

To determine if your dough ball passes the “doubled in size” stage, press the tip of your finger lightly and quickly about 1/2 inch into the dough.

If the impression you made stays in its place, the dough has doubled.

When using instant, the first fermentation process could be faster.

After the first fermentation, you degas the dough by pressing it down with your fist and releasing all the air. Then you start the fermentation process again.

Proofing Process

Proofing most commonly refers to the final rise a pizza dough undergoes, which takes place after the dough balls are shaped but before the pizza is shaped.

During the proofing stage, it produces gas, which imparts a level of aeration to the dough just before the baking stage.

The fermentation processes and chemical reactions during both the first rise (Bulk Fermentation) and the final rise (Proofing) are the same.

These fermentation processes are done primarily to:

  • Allow the dough to achieve a more exceptional flavor.
  • Develop gluten strains to trap in carbon dioxide, leaving a light and airy final product.

In pizza making, we proof the dough by retarding or slowing down this last fermentation process.

This second fermentation step is a much slower process at a lower temperature for a more extended period from 8 to 72 hrs.

Why Does Pizza Dough Need to Rise Twice?

You don’t need to follow the second fermentation process; however, it is highly recommended that you do a second fermentation.

The second fermentation is a slow process at a low temperature usually done in the refrigerator. It is recommended that you place the dough balls in the refrigerator for 8 to 72 hours. This allows the slow strengthening of the gluten and the development of flavors.

How Do You Activate Yeast for Pizza Dough?

To activate it follow this simple step-process:

Activating Yeast

Activate Yeast for Pizza Dough

Activating yeast is also known as “blooming”.

Step Process to Activate Yeast for Pizza Dough:

  1. Fill a container with water weighing five (5) times the weight of the yeast. For example, you have 5g of yeast, fill the container with 25g of water. 
  2. Set the temperature of the water to 95F (Instant) or 100F-105F (Active Dry). Do not heat the water in the microwave.  The temperature will be inconsistent if you do so.
  3. Stir the mixture
  4. Wait for 10-15 minutes

The mixture should be ready to mix with the rest of the water and the flour.

Never use water hotter than 100F-110F; the closer you are to the lower spectrum of temperature, the better the fermentation process you should be, nice and slow.

How Do You Know when Yeast is Activated?

After waiting 10 to 15 minutes after mixing the lukewarm water with the yeast you should see bubbles on the surface of the water as well as the sides of the mixture’s container.

How Does Activated Dry Yeast Looks Like?

It looks pretty much like a science experiment.

Activated Yeast for Pizza Dough

The color of the water should be milky, and you should be able to smell the aroma.

If any of these elements are not present, you should discard the mixture and start again with fresh ingredients.

How to Add Yeast to your Pizza Dough?

Adding yeast to your pizza dough is going to be different depending on which yeast you are using.

Adding Fresh Yeast to Pizza Dough

Since fresh yeast has the highest water content it doesn’t need to be activated, however can if you want to.

You do have to keep track of your water temperature. The same principle will apply, if the water is too hot it will kill the yeast.

how to add fresh yeast to flour

Adding Fresh Yeast to Pizza Dough

The best way to add fresh yeast to your dough is to crumble it on top of the flour just before mixing it.

You would treat it the same way you would add instant, by mixing it with the flour.

The mixing process will take care of incorporating all of it into the mixture.

Active Dry Yeast for Pizza Dough

The packets of active dry yeast say to dissolve it in warm water for best performance. We closely follow those directions.

Place the yeast in about five times its weight of water at 100°F. For example, if you are using 5 grams of yeast, add 25 milliliters of water to a container and combine them.

Stir the mix until thoroughly suspended and wait 10 minutes to begin the activation process. Once activated, you can add it to your regular dough water or right on top of the bread flour.

This process is not mandatory. Active dry yeast now comes in smaller granules that help it grow even when added directly to dry ingredients.

dough hydration

Adding Active Dry Yeast to Flour

Make sure you incorporate all the yeast mixture into the flour.

If you are accustomed to dissolving it in water first or if you need to make sure your yeast is alive, just keep doing that; it will save you time and flour if the yeast is not alive.

However, if you want to take the risk, you can. Just skip the whole activation process and add it directly to the flour.

What is the Best Way to Add Instant Yeast to Pizza Dough?

The best way to add instant yeast is to mix it with the dry ingredients first.

In this case, just place it right on top of the flour when you’re ready to begin mixing it.

Instant yeast does not need to be activated.

That is why so many people prefer it. They say is “convenient” not to have to activate it.

Adding instant yeast to flour

Adding Instant Yeast to Flour

The best way to add fresh yeast to your dough is to sprinkle it on top of the flour just before mixing it.

Can You Hydrate or Activate Instant Yeast?

Instant yeast is meant to be mixed with dry ingredients, in this case, with flour.

However, if you want to hydrate it, you can.

How to Activate Instant Yeast for Pizza Dough

Place the yeast in an amount of water that’s five times its weight at 95°F.

For example, if you are using 5 grams of yeast, to hydrate the yeast you should use 25 grams or milliliters of water.

Note the temperature is lower than for active dry yeast. That is because instant yeast is susceptible to water temperature.

Keeping track of the temperature is essential, a variation of as few as 5°F can result in some loss of the fermentation process.

Once it’s hydrated in the 95°F water, it can be combined with the rest of the water that will go to your dough mixture.

Does Yeast Affect Kneading and Shaping of Pizza Dough?

When handling yeast dough for homemade pizza, you need to take into consideration not to over-knead the dough, particularly if you are using a stand mixer.

When mixing the dough, you should set a timer, so the dough doesn’t get overworked.

Yeast won’t make a difference while you are kneading the dough because the kneading is mostly done by the mixer, not you.

However, the yeast will have a powerful effect on the shaping of the dough.

When it is time to shape the dough you will note that if you are using instant, the dough will be very elastic, like a rubber band, and it will shrink while you are trying to make the pizza crust shape.

You see more of this effect when you are flattening the dough with a rolling pin. The dough contracts to a smaller circle.

This is because since instant is fast-acting and the gluten didn’t have enough time to develop, making it very unstable.

On the other hand, if you use active dry yeast, the fermentation process is more prolonged allowing, the gluten to be more robust and more stable.

Active Dry vs Instant Yeast for Pizza Dough

These two yeasts are like siblings, although they share the same parents somehow you question yourself why are they so different?  Where you have the introverted child and the extroverted child.    

You can think of Active Dry yeast like the introverted child, quiet, slow-moving, and concentrated on what it needs to do.   Then you have the Instant yeast, the extroverted child, loud, fast-moving, and completely unpredictable.  Although effective as well. 

Since we are not going to analyze the psychology behind yeast, we can best explain their differences by analyzing the pro and cons of each one.

Pros and Cons of Active Dry Yeast for Pizza Dough

Refer to the table below to find all the Pros and Cons of both active dry and instant yeast.

Active Dry Yeast for Pizza Dough


  • Active Dry is widely available in most supermarkets and is less susceptible to temperature.  Accordingly, it will last longer.
  • You will get the same results every time, so you will know what to expect.  When it comes to shaping you will not have the shrinking effect, the dough will elastic but strong.


  • Being time-consuming is probably not a Con depending on how to look at it. Active Dry is a little lazy as it takes its time to wake up, which is perfect for pizza because it produces a long, slow fermentation process that helps build flavor.
  • Compared to Instant, active dry can be more perishable so always check the expiration date before using it.

However, if you are looking to make pizza in 1-day, active dry would not be the yeast to use.

Instant Yeast for Pizza Dough

When using instant you don’t know if the yeast is alive until you mix it and wait for the first rising period.  By that time, if your yeast is dead,  your yeast, flour, and most importantly your time will be a waste. Since instant yeast is more susceptible to temperature, you need to keep close attention to the water temperature, as any temperature above 100°F will kill the yeast.


  • Instant yeast is a favorite for those who don’t have or are not willing to spend the additional time in the kitchen and that is Ok.


  • Good luck trying you shape your dough, as is going to be very elastic, and you will have the shrinking effect.

To deal with a shrinking dough, just let it rest for 10 minutes to allow the gluten to relax.  Also, shape the dough an inch larger than your desired diameter so when it shrinks it ends at the size that you want.

  • Some additives, for example, ascorbic acid (Vitamin C) are typically added to instant yeast to better preserve it and the dough when is finally mixed.

You can still make good pizza with instant yeast, however, the results are not going to be the best. 

How to Convert Active Dry Yeast to Instant Yeast for Pizza Dough

To make things clear, the conversion rate from Active Dry to Instant is not technically interchangeable. As a general rule, you shouldn’t use the same amount of active dry as you would instant yeast.

Here is why, is like comparing lemons, let’s say lemon and lime, they are both from the same citrus family, but they are quite different. One is sweeter than the other, the color is different, the texture and its acidity.

The same principle applies to Active and Instant yeast for pizza dough; they are both from the same family or in this case from the same species, of dry yeasts, but they are different.

So, what makes them different? mostly water content.

Instant consists of 98% solids and 2% water, while Active Dry consists of 93% solids and 7% water.

Water will evaporate in the cooking process, so you end up with a 5% difference in solids from the two yeasts.

There are other differences as well such as the coating and the processing methods. But water content is the most significant difference making Instant yeast more concentrated and potent than Active dry yeast.

This is why it is also faster acting.

Conversion from Active Dry to Instant and viceversa

So, if a pizza dough recipe calls for Active Dry but you have Instant, just use 5% less of the required yeast.

On the other hand, if the recipe calls for Instant and you have Active dry just use 5% more of what the recipe calls.

Here is the caveat, when it comes to making homemade pizza, there is not going to be much difference in terms of volume or weight, on which type of yeast you are using when only small amounts of yeast are required.

For example, our Neapolitan Dough Base recipe calls for 10 grams of active dry yeast or 2% of flour (500g). If you were to use instant yeast you would need 9.5 grams of yeast (5% less). The difference between the two is not significant. Is it going to make a difference in your homemade pizza?

Probably not.

If you want to save the trouble of doing the numbers, you can substitute 1 : 1 only when you are handling small amounts of yeast.

However, when making large amounts of pizza dough, pay close attention to your numbers depending on what the pizza dough recipe requires.

Yeasticide: Meet the Two Rivals that Could Kill the Yeast

What can kill yeast?

Yeast has two rivals that if you don’t pay close attention to them, it could kill the yeast. So, who are these two adversaries? for a lack of a better term; the answer:


If yeast comes in direct contact with salt, it could be dead.


If the yeast is exposed to high temperatures, it will die.

 Salt should be the last ingredient you incorporate into your pizza dough when the yeast has already been activated and mixed with your flour.

This prevents having direct contact with it. Excess of salt will also affect the fermentation process; it will retard the whole process.

For that reason, salt should not be more than 3% of your total flour.

Water temperature to activate the yeast should be around 95 degrees F to 105 degrees F, temperatures higher than that will kill it. To be safe, just get yourself a digital thermometer and check your water before you introduce any yeast.

How to Keep Yeast Fresh

Yeast needs to be kept at a low temperature to avoid activation. So, keeping it in the refrigerator is a must. If you buy a large quantity, let’s say a jar, keep it in a tightly capped container or other airtight storage containers.

Fresh yeast will last roughly 2 weeks in the refrigerator, while dry will last for up to 2 months.

Yeast can also be kept in the freezer, and it will last several months, and in some instances for years.


Beware of unsealed open packets of yeast in the refrigerator. That yeast is dormant, wanting to awaken live and kicking.

The yeast will travel through the air and start fermenting whatever it finds to feed on in your refrigerator.

Which is the Best Yeast for Making Pizza?

If you are making a true Napoletana Pizza recipe, and you want to be as traditional as you can, the Associazione Verace Pizza Napoletana requires that you use fresh yeast. So, if you want to experiment with fresh yeast, you will want to use three (3) times more as much as you would active dry.

Or to be exact, take the grams of active dry and multiply by 3 = fresh yeast. For example, 10 grams of Dry Active x 3 = 30 grams of fresh yeast.

If the pizza dough recipe calls for fresh yeast, then divide the fresh yeast grams by 3.

We challenge you to try it out and see the difference. You will see fresh yeast creates more leavening gases, better flavors, and more robust and mature pizza dough.

Best Yeast for Pizza Dough (Overall Winner)

When having to choose between active dry or instant yeast for pizza dough, the winner is active dry yeast:

Active Dry Yeast

Active Dry Yeast is perfect for pizza makers. Its moderate regular gassing power provides the fermentation tolerance required for slow and cold fermentation, and its reduced power makes it easy to shape the pizza, thus avoiding the shrinking effect.

Here is What the PRO’s at Homemade Pizza Pro Use and Recommend

Best Instant Yeast for Pizza (Semifinalyst)

If we had to use any instant yeast, it would be SAF Instant. You can substitute active dry for SAF Instant in any of our recipes.

Just substitute it one for one.

This type of dry yeast gets going a little faster than active dry yeast, but no other adjustments are necessary.

The only downside is that it may give your crust a little “yeasty” taste after it is baked.

Least Favorite Yeast for Pizza Dough

For homemade pizza, we would recommend avoiding Quick-Rise or Rapid-Rise Yeast altogether. These are meant primarily for bread machines. It defeats the whole purpose of keeping the proofing process as slow as possible.

Are there Any Yeast Substitutes?

No, if you are serious about making pizza. Some people substitute yeast with baking powder or baking soda and an acid such as lemon juice, buttermilk, or milk combined with equal part vinegar. But this completely throws off the flavor of your pizza.

So, unless you have health concerns and for some reason, you cannot consume yeast, then we would recommend trying another form of crust such as vegetable options like cauliflower.

What Happens if You Put Too Much Yeast in Pizza Dough?

If you put too much yeast in your dough, it is going to act very fast, and your dough is going to rise in a very short time, but is this a good thing?

Maybe not, as there will probably not be enough time to develop the proper gluten, and you will not have any flavor profile.

Planning ahead of time and having all the ingredients set beforehand helps a lot in preventing these issues.

Yeast Best Practices for Pizza Dough

  • Always check the expiration date on the package.
  • Store it in a sealed air-tight container.
  • Is best to keep it at a temperature lower than 50°F.
  • Mix the yeast with water that is at a temperature of 95° to 110°F.
  • Yeast should not be more than 5% of your flour.
