The question seems simple enough: Is there yellow cheese with holes? The answer, however, is a resounding and fascinating “yes!” But the story behind those holes, or “eyes” as they’re often called, is far more interesting than a simple affirmative. It delves into the science of cheesemaking, the influence of specific bacteria, and the unique characteristics that define some of the most popular and beloved cheeses in the world. Join us as we explore this intriguing topic, uncovering the secrets behind yellow cheese with holes.
The Science Behind the Eyes: How Holes Form in Cheese
The iconic holes in certain cheeses aren’t accidental. They are a direct result of specific bacterial activity during the fermentation and aging process. It’s a natural byproduct of cheesemaking, a testament to the intricate dance between milk, cultures, and time.
The Role of Bacteria in Hole Formation
The primary culprit behind those distinctive eyes is Propionibacterium freudenreichii. This bacterium consumes lactic acid, a naturally occurring compound in milk, and converts it into propionic acid, acetic acid, and, crucially, carbon dioxide (CO2).
As the cheese ages, this CO2 is trapped within the semi-solidifying cheese matrix. Think of it like tiny bubbles forming in dough as it rises. The pressure from the accumulating gas creates pockets, which eventually become the characteristic holes we see. The size and distribution of these holes depend on several factors, including the amount of bacteria present, the temperature during aging, and the cheese’s overall moisture content.
Other Factors Influencing Eye Formation
While Propionibacterium freudenreichii is the main contributor, other factors play a significant role in the final appearance of the cheese.
- Temperature: Higher temperatures generally accelerate bacterial activity, leading to larger and more numerous holes. Cheesemakers carefully control the aging temperature to achieve the desired eye formation.
- Milk Composition: The quality and composition of the milk used to make the cheese also influence the process. Factors like fat content and protein levels can affect the cheese’s texture and its ability to trap CO2.
- Cheese Structure: The firmness and elasticity of the cheese curd also contribute. A firmer curd will trap the CO2 more effectively, resulting in larger and more defined eyes.
Popular Yellow Cheeses Known for Their Holes
Several varieties of yellow cheese are famous for their distinctive holes. These cheeses are enjoyed worldwide, each with its unique flavor profile and texture.
Swiss Cheese: The Archetypal Eye-Catching Cheese
When most people think of yellow cheese with holes, Swiss cheese is the first to come to mind. True Swiss cheese, traditionally made in Switzerland, is known for its large, prominent eyes and its nutty, slightly sweet flavor.
The specific characteristics of Swiss cheese, including the size and number of holes, can vary depending on the region and the cheesemaking techniques used. For example, some Swiss cheeses may have smaller, more evenly distributed eyes, while others may have larger, more irregular ones. The texture is typically firm and smooth, and the flavor intensifies with age.
Emmental: A Swiss Cheese Cousin
Emmental, another type of Swiss cheese, is also known for its holes. It’s often considered a close relative of Swiss cheese and shares many of the same characteristics. Emmental is traditionally made in the Emmental region of Switzerland. It has a slightly more pronounced flavor than some other Swiss cheeses, with a fruity and nutty undertone.
Emmental is frequently used in cooking, particularly in gratins and fondues, as it melts well and imparts a rich, savory flavor. Its large eyes and smooth texture make it a visually appealing addition to any cheese board.
Jarlsberg: A Norwegian Delight
Jarlsberg is a Norwegian cheese that also boasts distinctive holes. While technically a Swiss-type cheese, Jarlsberg has a milder, more buttery flavor than traditional Swiss cheese. It is characterized by its smooth, yellow interior and its medium-sized, evenly distributed eyes.
Jarlsberg is a versatile cheese that can be enjoyed on its own or used in a variety of dishes. Its mild flavor and meltability make it a popular choice for sandwiches, salads, and baked goods. It’s a great option for those who enjoy the visual appeal of holes but prefer a less intense flavor.
Why Choose Cheese With Holes? Considerations for Taste and Texture
The presence of holes in cheese isn’t just a visual characteristic; it can also influence the cheese’s taste and texture.
Flavor Nuances
The bacterial activity that creates the holes also contributes to the cheese’s overall flavor profile. The fermentation process produces various compounds, including propionic acid and acetic acid, which contribute to the cheese’s distinctive taste. In some cases, the holes can also trap moisture, which can enhance the cheese’s creaminess and mouthfeel.
Texture Considerations
The holes in cheese can also affect its texture. Cheeses with large, numerous holes tend to be more airy and less dense than cheeses without holes. This can make them easier to melt and incorporate into dishes. The holes can also create a unique mouthfeel, adding a pleasant textural contrast to the cheese.
Health Benefits
Beyond taste and texture, there is a nutritional aspect as well. Cheeses like Swiss and Emmental are a good source of protein, calcium, and other essential nutrients. The fermentation process can also make these cheeses easier to digest for some people.
Storing Yellow Cheese With Holes
Proper storage is essential to maintaining the quality and flavor of your cheese. Cheeses with holes are no exception.
Optimal Storage Conditions
To keep your cheese fresh, store it in the refrigerator, ideally wrapped in cheese paper or plastic wrap. This will help to prevent it from drying out and absorbing odors from other foods in the refrigerator.
Preventing Mold Growth
Mold can sometimes grow on cheese, even when stored properly. If you see mold on a hard cheese like Swiss or Emmental, you can often cut away the moldy portion, making sure to remove at least an inch around the affected area. The rest of the cheese should be safe to eat. However, if you see mold on a soft cheese, it’s best to discard the entire piece.
Extending Shelf Life
To extend the shelf life of your cheese, consider wrapping it tightly in plastic wrap and storing it in the freezer. While freezing can slightly alter the texture of the cheese, it’s a good option for preserving it for longer periods. When you’re ready to use the frozen cheese, thaw it slowly in the refrigerator.
Beyond the Familiar: Exploring Other Cheeses With Holes
While Swiss, Emmental, and Jarlsberg are the most well-known examples of yellow cheese with holes, other varieties also exhibit this characteristic.
Raclette
Raclette, a Swiss cheese traditionally melted and scraped onto potatoes and other accompaniments, often has small to medium-sized holes. Its flavor is nutty and slightly pungent.
Comté
Comté, a French cheese similar to Gruyère, can also have small holes. Its flavor profile is complex and nuanced, ranging from fruity and nutty to slightly spicy.
Exploring Regional Variations
Many regional variations of Swiss-type cheeses exist, each with its own unique characteristics and hole formation. Exploring these cheeses can be a great way to discover new flavors and textures.

Why does some cheese have holes?
The holes in cheese, often referred to as “eyes,” are primarily caused by the production of carbon dioxide (CO2) gas by certain bacteria during the cheese-making process. Specifically, bacteria like Propionibacterium freudenreichii consume lactic acid and produce CO2, propionic acid, and acetic acid. These gases create bubbles within the cheese matrix, and as the cheese matures, these bubbles coalesce and form the characteristic holes.
The size, shape, and distribution of these eyes can vary significantly depending on factors like the type of bacteria used, the temperature of the aging process, and the moisture content of the cheese. Some cheeses have small, evenly distributed eyes, while others have large, irregular ones. The presence and characteristics of the eyes are often considered indicators of a cheese’s quality and flavor profile.
Is Emmental the only yellow cheese with holes?
While Emmental is perhaps the most well-known yellow cheese with holes, it is certainly not the only one. Other cheeses also exhibit this characteristic, though their specific flavor profiles and textures may differ considerably. Examples include Jarlsberg from Norway, which features large, shiny eyes and a nutty flavor, and some varieties of Swiss cheese beyond Emmental, also characterized by their distinctive eyes.
The formation of holes is more about the cheese-making process and the bacteria involved rather than a unique property of a single cheese type. Many producers may intentionally add cultures of Propionibacterium to achieve this effect, leading to variations in eye development across different cheese types and geographical regions. Therefore, searching beyond Emmental will unveil a diverse landscape of yellow cheeses with holes.
What influences the size and number of holes in cheese?
Several factors during cheese production influence the size and number of holes, or “eyes,” in cheese. The type and amount of Propionibacterium bacteria used are primary determinants. A higher concentration of these bacteria results in increased CO2 production and, subsequently, more and larger holes. Temperature control during the aging process is also critical, as warmer temperatures accelerate bacterial activity and gas production.
Furthermore, the moisture content and acidity of the cheese curd play significant roles. A higher moisture content allows for easier gas diffusion and the formation of larger holes, while the acidity level affects bacterial growth and activity. Manipulating these variables allows cheesemakers to control the final appearance and texture of the cheese, including the size and distribution of the eyes.
Can cheese with holes go bad faster?
The presence of holes in cheese does not necessarily mean it will spoil faster than cheese without holes. Spoilage is typically caused by the growth of undesirable bacteria or mold, which is independent of the presence of eyes created by Propionibacterium. However, improperly stored cheese with holes might have a slightly larger surface area exposed to the air, potentially leading to faster drying or the development of mold on the cut surfaces.
Proper storage is key to preventing spoilage regardless of whether the cheese has holes or not. Wrapping the cheese tightly in plastic wrap or storing it in an airtight container in the refrigerator will minimize exposure to air and moisture, thus extending its shelf life. Regularly check the cheese for signs of spoilage, such as discoloration, off-odors, or the growth of mold on the surface, and discard it if any of these are present.
Does the type of milk affect the holes in cheese?
While the type of milk primarily impacts the flavor and texture of the cheese itself, it indirectly affects the holes. The composition of the milk, specifically its fat and protein content, can influence the curd structure and the environment in which the Propionibacterium bacteria thrive. Milk with higher fat content may result in a richer, more pliable curd, which can impact the size and distribution of the holes.
Furthermore, the pasteurization process and the presence of naturally occurring bacteria in the milk can influence the overall microbial ecosystem within the cheese. These factors can, in turn, affect the activity of the Propionibacterium and, consequently, the formation of the holes. Although the direct impact is subtle, the milk’s characteristics contribute to the overall environment that shapes the cheese’s final appearance.
Are the holes in cheese a sign of good quality?
The presence of holes in cheese, particularly in varieties like Emmental or Jarlsberg, is generally considered a sign of proper fermentation and a well-executed cheesemaking process. Well-formed, evenly distributed eyes often indicate that the Propionibacterium bacteria were active and produced the characteristic CO2 gas in a controlled manner. However, the size, shape, and abundance of the holes must be consistent with the specific cheese type.
However, the absence of holes does not automatically indicate poor quality. Many delicious and high-quality cheeses, such as cheddar or Gouda, are intentionally made without eyes. Furthermore, excessively large or irregularly shaped holes can sometimes indicate undesirable bacterial activity or improper aging conditions. Ultimately, the quality of the cheese depends on a combination of factors, including flavor, texture, aroma, and appearance, with the holes being just one element to consider.
Can I make cheese with holes at home?
Making cheese with holes at home is possible but requires a good understanding of cheesemaking principles and a controlled environment. The key is to introduce Propionibacterium freudenreichii bacteria at the right stage of the cheesemaking process. This can be achieved by adding a specific cheese culture containing this bacteria to the milk during fermentation.
Maintaining the correct temperature during the aging process is also crucial for the bacteria to produce CO2 and form the characteristic eyes. Typically, a warmer temperature range (around 70-75°F) is needed during the initial aging phase. This requires careful monitoring and precise temperature control. While challenging, with proper equipment and attention to detail, creating your own cheese with holes is a rewarding experience for adventurous home cheesemakers.
