Quick Yeast Cheat Sheet

  • Best overall yeast: Active dry yeast (versatile, reliable, and economical in bulk).
  • Ideal water temperature: Warm to the touch, roughly 105 to 110 degrees Farenheit (water above 125 degrees will render yeast inactive).
  • Best storage location: Sealed tightly in the refrigerator after opening will help it last up to one year.
  • How to test if yeast is alive: Combine warm water, a pinch of sugar, and yeast. If the mixture becomes frothy after 5 minutes, it’s ready for you to use.

What Kind of Yeast Should I Use?

Personally, I prefer to use active dry yeast for pretty much any time I’m baking with yeast. Quite simply, it works.

Instant yeast is what people typically use for bread machine recipes, but it really isn’t that different from active dry yeast other than the granules being smaller.

For the most part, avoid rapid rise yeast or cake yeast. Rapid rise yeast gives only a single rise, and cake yeast stays working and active for an extremely short time, so unless you’re doing a ton of baking… skip it.

For almost every recipe, active dry yeast is the best choice. It yields consistent results and works for everything from soft dinner rolls to artisan French baguettes.

Yeast TypeBest Used ForKey Characteristics
Active Dry YeastAlmost all bread and dough recipesMost versatile option, reliable rise, and long shelf life when cold.
Instant YeastBread machine recipesSmaller granules, dissolves faster, and can be mixed directly into dry ingredients.
Rapid Rise YeastQuick single-rise breadsForces a fast single rise, but skips the second rise that develops deep flavor.
Cake YeastCommercial or daily bakersFresh yeast block with a very short shelf life that spoils quickly at home.

How to Store Yeast to Keep It Fresh

If you buy packets of yeast, you can keep them in a cabinet until their expiration date. Honestly, the packets are far more expensive than buying a jar of yeast. Get the jar if you plan to bake more than a few times a year.

Once you open the jar, store it tightly sealed in the coldest part of your fridge. It stays active for a year or so.

I purchase the active dry yeast “brick” at Costco, which is a pound of active dry yeast. I put as much yeast as fits into the old yeast jar I have to store in the fridge to use.

The remainder of that one-pound brick goes into a tightly sealed container that I store in the freezer when I have a ton left, or in the fridge if I’m near the end. I just refill the small jar as needed, so I don’t expose my entire supply to air every time I bake.

Whatever you do, once you open yeast, don’t leave it sitting at room temperature.

What Water Temperature Is Best for Yeast?

Yeast stops working when exposed to liquid temperatures starting at about 125 degrees Fahrenheit. Thankfully, your tap water generally isn’t that hot.

To activate yeast properly, aim for water that is comfortably warm to the touch, similar to warm bathwater. You do not need an instant-read thermometer. If the water feels hot on your wrist, let it cool down a bit before mixing it with your yeast.

Technically, you can use cold or cool tap water, but your dough will take significantly longer to rise. Warm water gives the yeast a gentle jump-start without heat damage.

Does Your Kitchen Need to Be Warm for Dough to Rise?

Guess what? Your kitchen does not need to be warm for dough to rise. Yeast will still grow in a cool room, though the dough will simply rise at a slower pace.

To help your dough rise smoothly in a cooler kitchen:

  1. Start with comfortably warm water when mixing your dough.
  2. Immediately cover your bowl with a slightly damp kitchen towel after kneading.
  3. Keep the bowl away from cold drafts.

The towel traps warmth, retains moisture, and allows the yeast to breathe while keeping the dough surface from drying out. If your kitchen is hot and humid, monitor your dough closely, as it may double in size much faster than the recipe predicts.

Can You Let Dough Rise in the Fridge Overnight?

Yes, you can let dough do its rise in the refrigerator, and I often let my dough sit in the fridge for various reasons. Cold temperatures slow down yeast activity without stopping it entirely, which actually allows deep, complex flavors to develop in the dough.

Keeping yeast dough in the fridge works exceptionally well for two scenarios:

  • Overnight Breakfast Bakes: Prepare recipes like cinnamon rolls or monkey bread the night before so you can enjoy them first thing in the morning. Shape the dough, place it in the baking pan, and let it do its second rise in the fridge overnight. In the morning, pop it straight into the oven.
  • Batch Baking: Make a large batch of dough, cover it, and place it directly in the fridge for its first rise. When you’re ready to bake, just remove the portion you need, shape it, allow it extra time to warm up and rise, and bake as directed.

Do You Need to Proof Yeast?

You do not need to proof yeast if you know your yeast is fresh and stored properly. Proofing simply means proving that the yeast is alive before adding it to the rest of your ingredients.

This is also why you want to check the expiration date on any yeast you buy at the store. I once almost bought a jar of yeast that was two years expired – no thank you!

I make homemade sandwich bread and pizza dough often enough that I know my yeast is good. I skip this step most of the time.

If you have a fresh jar of yeast that you use regularly like me, you can skip this step and mix it straight in. However, if your yeast has been sitting in the fridge for more than six months, or if it’s near its expiration date, proofing prevents you from wasting flour and time on inactive yeast.

How to Proof Yeast Step-by-Step

To proof yeast:

  1. Combine 1/4 cup of warm water, 1/2 teaspoon sugar, and your recipe’s required amount of yeast in a bowl.
  2. Let the mixture sit undisturbed for 5 minutes.
  3. Check the surface. If it’s frothy, foamy, and smells bread-like, the yeast is active. If the water remains flat and clear, toss it out and buy fresh yeast.

Note that when you make your recipe, reduce the water by 1/4 cup since you have already used 1/4 cup to proof your yeast. Simply add this mixture to your mixing bowl and continue on with your recipe.

Should You Use the Oven Proofing Setting?

I wouldn’t. First of all, your dough will rise, even if you have a cooler kitchen. 

But more importantly, when you use the proofing setting in your oven, many ovens are set too warm, which can create an off-flavor in the bread or cause the dough to overproof rapidly. The few times I have done this, I always regret it.

Room temperature proofing results in a better texture for your finished bread, and with all the effort you put into making something, you want it to be the best it possibly can be. If you’re really stuck on time, go for it, but try to be patient and skip your oven or Instant Pot.

The only exception to proofing in the oven is when I make frozen croissants from Trader Joe’s and forgot to take them out the night before! If that’s you, check out my frozen croissant proofing tutorial.

What Does Overproofing Mean?

Overproofing is what happens when you let your dough rise for too long. The gas bubbles (hello burping yeast!) got too active and stretched the dough more than it should.

If you get your bread to this point, you risk it falling flat because the structure you created with the bubbles can’t expand any further when you bake it. You’ll end up with unsightly loaves that don’t have the texture you want.

Overproofed dough looks puffy, collapses easily when touched, and it bakes into a dense, flat loaf. You want your dough to rise enough that it feels soft, not firm, when you poke at it, but don’t let it go past that point.

How to Fix Overproofed Dough

Thankfully, you CAN save dough that you overproofed. Don’t just throw it away, and don’t bake it as is.

Deflate the dough: Gently press or punch down the overproofed dough to release the excess gas.

Reshape: Remove the dough from the pan, reshape it into your desired form, and place it back in the baking dish.

Second Rise: Let the dough rise a second time. Keep a close eye on it, as it will rise much faster than it did the first time. Bake it as soon as it feels soft and yields gently to a light touch.

Generally, you won’t be able to tell the difference between dough you saved after it overproofed and dough you proofed the first time correctly!

    1. It depends on what kind of bread you’re making. Different types of bread use different amounts of yeast whether it’s a baguette or sandwich bread or a brioche, etc.
