As a key ingredient in baking and brewing, yeast is a staple in many kitchens. It has been used for thousands of years to leaven bread, ferment beer, and make wine.
But what about using it fresh?
Using fresh yeast can take your recipes to the next level and give you the best results. In this article we’ll explore some tips on how to use fresh yeast in your recipes.
What is yeast fresh
Yeast fresh is a type of yeast that has not been dried or processed in any way. It is harvested directly from the brewery and is alive and active when it arrives at your kitchen. This type of yeast is typically more expensive than dry yeast, but it can be worth the extra cost due to its superior flavor and performance. Fresh yeast works best when it’s kept at a cool temperature, so it’s best to store yeast fresh in the refrigerator until you’re ready to use it.
Importance of yeast fresh in baking and brewing
Yeast fresh is an incredibly important ingredient for baking and brewing, as it provides a wide range of flavors, textures, and aromas that can’t be achieved with dry yeast. Fresh yeast is especially important in beer making because it adds complexity to the flavor profile of the final product. When used in baking, fresh yeast helps create a fluffy texture and rich flavor that you won’t get with dry yeast.
Types of Yeast Fresh
Baker’s yeast
Baker’s yeast is a type of fresh yeast that is commonly used for bread baking. This type of yeast is available in active dry, instant, and fresh forms. Baker’s yeast contains more moisture than other types of fresh yeast, so it should be stored in the refrigerator to prevent it from drying out. When using baker’s yeast, you should dissolve it in warm water before adding it to your recipe.
Brewer’s yeast
Brewer’s yeast is a type of fresh yeast that is used in the production of beer and other alcoholic beverages. It is typically sold in dry or liquid form, but it can also be purchased as fresh slurry from a brewery. Brewer’s yeast should be kept refrigerated to keep it active, and it should be added directly to the wort when making beer.
Wine yeast
Wine yeast is a type of fresh yeast that is used in the production of wine. This type of yeast is available in dry and liquid forms, but it can also be purchased as a fresh slurry directly from wineries. Wine yeast should be stored in the refrigerator to keep it active, and it should be added directly to the must when making wine.
Characteristics of Yeast Fresh
Living organism
Yeast fresh is a living organism. It requires food, water, and oxygen to survive in order to stay active for baking and brewing purposes. Yeast fresh also produces carbon dioxide when it is metabolizing, which helps leaven doughs and creates bubbles in beer. The flavor of yeast fresh varies depending on the species, but it generally has a slightly sweet taste that complements many recipes.
Fungi classification
Fungi are classified into three divisions: Ascomycota, Basidiomycota, and Zygomycota. Ascomycota includes yeasts, molds, and mildews; Basidiomycota includes mushrooms; and Zygomycota includes bread and beer molds as well as food-spoilage molds. Yeast fresh is classified as an Ascomycota because it is a single-cell organism without any visible fruiting body.
Reproduction through fermentation
Reproduction through fermentation is a process that occurs when yeast breaks down carbohydrates into alcohol and carbon dioxide. During the fermentation process, yeast cells reproduce by forming new cells from old ones. This occurs when the old cells convert sugar molecules into energy, which then allows them to divide into two new cells. As a result of this process, yeast produces alcohol and carbon dioxide, which are key ingredients in baking and brewing.
Sensitive to temperature and humidity
Yeast fresh is sensitive to temperature and humidity levels. It should be stored in a cool, dry place at temperatures between 39-59 degrees Fahrenheit. If the environment is too cold, the yeast may become inactive or dormant, while too much heat will cause it to die off. Additionally, high humidity can lead to mold growth on the yeast which will render it unusable for baking and brewing.
Applications of Yeast Fresh
Baking
Baking is one of the most common applications for yeast fresh. When used in baking, fresh yeast helps create a fluffy texture and rich flavor that you won’t get with dry yeast. To use it in baking recipes, the yeast should be dissolved in warm water before adding it to the other ingredients. It’s important to keep an eye on the temperature of the water so as not to kill the yeast.
Brewing
Brewing is another popular use for yeast fresh. In the brewing process, yeast is used to convert sugars into alcohol and carbon dioxide, which are key ingredients in beer. When making beer, the yeast should be added directly into the wort and kept at a temperature between 60-75 degrees Fahrenheit to ensure optimal fermentation. In addition, high humidity can lead to mold growth on the surface of the yeast, so it should be stored in a cool, dry place.
Fermentation of food and beverages
Fermentation of food and beverages is an age-old process that has been used to preserve, flavor and improve the nutritional value of a wide variety of foods and beverages. This process involves the use of microorganisms such as bacteria, yeast, and fungi to convert carbohydrates into alcohol or acid.
Throughout history, this process has been used to make beer, wine, cheese, yogurt, pickles, and even bread. Yeast fresh is a key ingredient in this process, as it helps to create the complex flavors and textures associated with these foods and beverages.
Storing and Keeping Yeast Fresh
Proper storage methods
Yeast fresh should be stored in a cool, dry place at temperatures between 39-59 degrees Fahrenheit. It is also important to keep the yeast out of direct sunlight and away from other sources of heat as this can cause it to die off.
Additionally, high humidity can lead to mold growth on the yeast which will render it unusable for baking and brewing. To ensure optimal shelf-life, it is recommended that the yeast be stored in an airtight container.
Shelf life and expiration dates
When stored properly, yeast fresh can last up to six months if kept in an airtight container at temperatures between 39-59 degrees Fahrenheit.
After this time period, the active components of the yeast can start to break down, making it less effective when used in baking or brewing. It is important to check the expiration date prior to using yeast fresh to ensure that it is still active and not expired.
Tips for keeping yeast fresh
Yeast fresh should be stored in an airtight container in a cool, dry place at temperatures between 39-59 degrees Fahrenheit. It is also important to keep the yeast out of direct sunlight and away from other sources of heat as this can cause it to die off.
Additionally, high humidity can lead to mold growth on the yeast which will render it unusable for baking and brewing. Proper storage and maintenance can help prolong the yeast’s shelf-life and ensure optimal results when used in baking or brewing applications.
Choosing the Right Yeast Fresh
Consider the recipe
When choosing yeast fresh for a recipe, it is important to consider the type of recipe and the desired results. Different types of yeast can be used in different recipes, depending on the desired flavor profile and texture.
For example, active dry yeast adds a mild flavor and light texture while instant yeast can produce a faster rise time and richer flavor. Additionally, certain recipes may call for specific types of yeast, such as fresh cake yeast or dry active yeast.
Understand the fermentation process
Understanding the fermentation process is essential when using yeast fresh. Fermentation is a process that involves the use of microorganisms such as bacteria, yeast, and fungi to convert carbohydrates into alcohol or acid.
This process can occur naturally over time or be accelerated by adding yeast fresh to the mixture. During this process, carbohydrates are broken down by enzymes secreted by the microorganisms and converted into carbon dioxide and ethanol.
The carbon dioxide is responsible for the leavening effect in breads, while the ethanol creates the complex flavors associated with fermented foods and beverages.
Choose the right style for brewing or baking
When using yeast fresh for brewing or baking, it is important to choose the right style of yeast to achieve the desired results. For example, ale yeast is often used for brewing beer as it ferments quickly and produces a strong hoppy flavor, while lager yeast works best for producing a crisp and smooth flavor. For baking applications, instant yeast can provide an improved rise and texture in breads, while dry active yeast is better suited for creating richer flavors and a more robust crumb. Understanding the types of yeast and their uses can help ensure a successful outcome when using yeast fresh.
