How Long Does Fresh Yeast Last?

Fresh yeast, also known as compressed yeast or cake yeast, is the OG of commercial yeast.

It has been around since the mid-19th century, and boy, does it have a story to tell! Sold in blocks or cakes that resemble crumbly, cream-colored modeling clay, fresh yeast is a powerhouse of flavor and leavening power.

Now, let's get down to business.

Fresh yeast has the highest moisture content of any form of baker's yeast, with each gram containing roughly six billion active yeast cells. That's a whole lot of tiny organisms working their magic!

But here's the catch: fresh yeast is highly perishable. Once you open that package, you've got about 2-3 weeks to use it up before it starts losing its potency. So, it's important to store it properly and keep an eye on those expiration dates.

Fresh Yeast Expiration Date

The expiration date is prevalent on various food items, including fresh yeast. This date indicates the period during which the yeast remains active, based on optimal storage conditions.

However, you might have forgotten about the yeast package in your fridge's back.

Don't worry! If the yeast is well wrapped, it might last a few extra days.

Nonetheless, the yeast begins to lose its strength a few days after the printed date.

Fresh Yeast Use-by Date

Now, let's talk about the use-by date.

This is the date by which the yeast is recommended to be used for best results. If you're a frequent baker, you probably go through fresh yeast like there's no tomorrow.

But for those of us who dabble in baking occasionally, it's important to keep an eye on that use-by date. Once the yeast is past its prime, it won't work as effectively, and your baked goods may not rise to their fullest potential.

Storing Fresh Yeast

Storing fresh yeast requires adherence to a few guidelines, given its highly perishable nature. It needs some tender loving care, especially after the package is opened.

Crucially, the yeast should be stored in the fridge where the cool temperature slows down its activity and extends its lifespan.

Fresh Yeast Storage Guidelines

Now, let me share some insider tips on how to store fresh yeast like a pro.

First things first, tightly wrap the yeast in its original packaging or place it in a freezer bag.

This will help keep it fresh and prevent any funky odors from permeating your fridge. Trust me, you don't want your leftover Chinese takeout to mingle with your yeast!

If you're planning to store fresh yeast beyond the printed date, freezing is your best bet. Simply cut the yeast into pieces, wrap them tightly in cling film and aluminum foil, and store them in a zip bag or airtight tub.

This will protect the yeast from freezer burn and ensure its longevity.

But here's the catch: thawed yeast should be used within two to three days after thawing. So, if you're freezing a big batch, make sure to portion it out accordingly.

And remember, gradual thawing is key.

Transfer the airtight container from the freezer to the fridge and let it thaw slowly.

This will help preserve the yeast's quality and ensure it's ready to work its magic when you need it.
