How many teaspoons in 1 package of yeast?
A regular package of yeast will usually contain 2-2tsp+¼ tsp of yeast. A packet of bread yeast weighs approximately 7-8 grams and typically contains 2.25 tsp of yeast. Rapid Rise Yeast, Fast Rising Yeast, or Bread Machine Yeast contains 2 1/4 teaspoons of yeast that equals 7 grams, or 1/4 ounce.
The function of Yeast in baking
Yeast is a fungus that consists of a single cell. As the baking powder, it also acts as a leavening agent in baking. But the process through which it produces carbon-di-oxide is biological. The biological reaction, called fermentation, uses the starch in bread and ferments it to gas, alcohol, and water.
The alcohol evaporates during baking but helps develop gluten and add a lot of flavor to the bread, unlike baking powder. The gas produce helps raise the bread.
Different types of Yeast used in baking
It has a smaller grain size and a greater number of live yeast cells per unit volume than active dry yeast. As the name suggests, this yeast needs no time for rehydration and is directly poured into the dough mixture.
High salt and sugar concentration hinder yeast growth. Hence, in bread with higher sugar content, osmotolerant yeast comes to the rescue.
Cream yeast is just compressed yeast in a liquid state. This compressed yeat slurry is widely used by bread industries.
Active dry yeast
It is relatively stable than other forms of yeast and has bigger grains than instant yeast. It is sold in its dormant form and requires proofing before adding to the dough.
As the name suggests, it is used by breweries to make alcohol. Brewer’s yeast is also used for its nutritional benefits. It keeps the digestive system healthy and has considerable amounts of chromium.
It is a type of instant yeast but with smaller grain size and a greater dissolution rate. It provides a pronounced carbon dioxide yield.
It is basically dry cream yeast shaped into small or large blocks wrapped with foil. Despite being very perishable, it is still used in bakeries.

How to perform a freshness test for yeast?
You cannot tell by looking at the yeast if it is dead or not. Perform the test below to check if the yeast is active.
- In a cup, take ¼ cup lukewarm water. It is best to check the temperature of the water using a thermometer and make sure it lies between 110-115°F. A temperature higher than 120°F will destroy your yeast. A temperature lower than 110°F will not be able to activate the yeast to its full potential. To the water, add 1 ¼ tsp of yeast and 1 tsp of granulated sugar.
- Give it a stir until yeast is dissolved completely. Wait for 10-15 minutes.
- If the yeast forms bubbles or foam on the surface and you smell a strong yeasty aroma, the yeast is active. If not, the yeast is dead.
This proofing test can also be performed with a small amount(walnut-sized) dough.
How to store yeast?
There are two types of yeast that are used frequently by home bakers and commercial bakeries namely:
- Dry yeast
- Fresh yeast
Dry yeast is quite shelf-stable due to which an unopened packet of dry yeast will be good in the pantry if kept away from stove heat, direct sunlight, and moisture. As soon as you open the packet, the dormant yeast granules become vulnerable to spoilage. Therefore, it needs to be refrigerated.
You cannot refrigerate dry yeast in an open packet. The humid environment of the fridge will destroy the quality of yeast. To overcome this, transfer the yeast to a zip-locked freezer bag and store it.
Fresh yeast, also called, cake or compressed yeast is more susceptible to spoilage. It is sold in refrigerated form and must be stored in the refrigerator t keep it alive.
