You can find yeast in the baking aisle of grocery stores like Walmart, Target, and Kroger. It is usually found along with other baking ingredients like baking soda, baking soda, and cornstarch. Dry yeast is probably represented here as well as nutritional yeast and active yeast.
Active dry yeast, along with instant, is typically found in the bakery section of grocery stores, alongside other dry ingredients such as flour and baking powder.
The most common yeast you’ll find in grocery stores are individual packets or jars of active dry yeast. This store-bought yeast has a longer shelf life than fresh block yeast (or cake yeast) if sealed and kept at room temperature and left to rest until activated by warm water.
Yeast comes in two forms: (1) Fresh yeast (also called compressed cakes) and (2) Dry yeast (also called dehydrated granules). Soft and moist, fresh yeast is used primarily by professionals. It needs to be refrigerated or frozen as it is perishable. Fresh yeast must rise before use.
Therefore, unlike using yeast, using baking powder does not require any additional proofing time. Because of this, it is used to leaven quick breads like pancakes, cornbread, cookies, and cakes. In baked goods you can replace yeast with the same amount of baking powder.
Reid calls fresh yeast a “special occasion yeast” that’s best used for occasions when you bake a lot, such as professional bakers tend to say that this yeast is the best yeast for bread because it gives a stronger taste.
“Active” describes any dry yeast that needs to be activated before use, while “instant dry yeast” describes any dry yeast that is ready to use immediately after opening the package.

There are three main types of commercially produced baker’s yeast: active dry, instant and fresh. All of them lend themselves well to leavening in any given yeast-based baking recipe, but each has slightly different properties and, for the more discerning palate, different flavors.
