What is Yeast, and How Does it Work?

If you’re new to the bread-baking world, you might be scratching your head over what yeast is in the first place. Most people have heard of yeast and know the utter importance of this ingredient for bread, but many bakers don’t know what it is. Let’s discuss it real quick.

Yeast is a live, single-cell fungus that can only be seen through a microscope. When used to bake bread, yeast does two things: ferments sugars and releases carbon dioxide. This causes gasses to expand in the dough, allowing it to rise. 

Not only is yeast essential for allowing your bread to rise the way it is supposed to, but it also helps the bread achieve perfect flavor and texture. So if you’re seeking a light and fluffy slice of bread, don’t skip on the yeast!

How Much Yeast is in a Packet?

Okay, now let’s get down to why we are all here today to talk about how much yeast is in a packet. We all know that recipes typically call for a “packet” of yeast. But how much yeast is actually hiding inside?

One yeast packet will typically contain 2 ¼ teaspoons of yeast, which can also be measured as ¼ ounce or seven grams. 

Are All Packets of Yeast Created Equal?

There are many types of yeast available on the market, including active dry yeast (the most popular), instant yeast, rapid rise yeast, and fast-rising yeast. With so many options, you might think that the amount changes per the type of yeast.

This is not the case, though. It does not matter which type of yeast you’re using. Whether you’re purchasing active dry yeast, instant yeast, or another type of yeast, the amount will remain the same – 2 ¼ teaspoons or ¼ ounce.

The brand also does not change the amount of yeast that is inside a packet. So, don’t panic when you’re at the grocery store and need to purchase yeast. All packets are created equal and will function well in your recipe.


A packet of yeast, regardless of the type, contains 2 ½ teaspoons of yeast inside. Your recipe will typically call for one or two packets, depending on what you’re making. If you still have questions about how much yeast is in a packet, check out these handy questions below.

    I just stumbled on your great website while looking things up for my wife. She just moved to the US (Boston) from Italy and is having a hard time finding the yeasts she needs for breads, pizzas etc. In particular she is looking for live Yeast. Do you have a suggestion on where to buy it and if there is a preferred brand for each type of yeast (beer, instant etc)?

      Hi Andre,
      She should be able to find live yeast at any local grocery store or big box stores such as Walmart or Food 4 Less. King Arthur and Fleischmanns are good brands for instant yeast.
      Let me know if you have any other questions!
