Fresh yeast or instant dry yeast? What should I use in my bakery?

Let’s start by understanding what yeast is. Yeast is a fungus that produces enzymes to convert sugars into alcoholic fermentations is able to convert sugar or carbohydrates, into important substances and nutrients for the body. The yeast acts on the doughs increasing their volume and giving them flavor and sponginess.

Biological yeast is a unicellular living microorganism known as SACCHAROMYCES CEREVISIAE (sugar fungus), which has the capacity to produce gas through the transformation of available sugars which helps us to increase the doughs their volume to later be baked.

Types of yeast:

Yeast is mainly used in the bakery for the preparation of doughs, it can also be used in pastry processes or those products that need to be leavened. Since as mentioned the objective of the yeast is to grow the doughs giving more volume before entering the oven.

You will then be able to differentiate the types of yeast you can find on the market.


It is natural yeast, which must be created from scratch. For its preparation, equal amounts of flour and water are mixed, leaving it to rest for 5 days until it ferments , an excessive time can generate damage to the sourdough, on fermentations and unwanted flavors. After this process it can be used for the preparation of sourdough bread.

Chemical yeast (baking powder):

The term chemical yeast is commonly used in other countries, but refers to baking powder or baking soda, this yeast is a chemical or gasifying driver that, when in contact with water, generates bubbles that make the dough fluffy. It is commonly used in pastry products.

It is produced artificially so it is not a biological agent. What we are looking for in this article is to compare strawberry yeast and instant dry yeast, both of which are biological agents.

instant dry yeast

It is a fresh yeast drying technology. It is dried in a similar way to dry active yeast and then vacuum packed, which allows it to last 2 years with the packaging closed and in optimal conditions, once opened the product only lasts 72 hours.

During this drying process between 35°C and 40°C the yeast suffers, weakens and approximately 18% of yeast cells die.

For its activation you must dilute it in warm water and then add it to the dough, either to prepare bread, pizza, empanadas or other similar doughs for various products of your bakery and pastry. This process corresponds to dry active yeast, because instant dry yeast is incorporated directly onto the flour.

Fresh Yeast

It is a 100% natural and fresh product, you can find it pressed in block. When asked how fresh yeast should be preserved; We recommend always keeping it in the fridge in a container with a hermetic closure because it has a wet consistency that can be damaged by sudden changes in temperature or when in contact with other substances.

In the bakery world it is very common to make equivalences between fresh and dry yeast depending on the preparation of bread that you want to make, then we share the table of equivalences between yeasts.

How much does fresh yeast equal to dry?

When preparing a recipe, it is important to pay attention to the amounts indicated, so you should take into account this picture that we will share.

Table of equivalences between fresh and dried yeast:

Fresh yeast

Instant dry yeast

14 g

5’5 gr

42 g

16 g


To calculate the amount of yeast in equivalent portions, you need to use a rule of three. For example, in equivalence 3 to 1 of fresh yeast by dry yeast its equivalent should be 9 grams. If it is 2.5 to 1 its equivalence is 7.5 grams. On the other hand, if the recipe does not specify the type of yeast or if quantities greater than 15 grams are required for its preparation, you should safely use fresh yeast.
