What You'll Learn
White spots are good
Don't be alarmed if you see those little white spots on your cheddar cheese. They are a completely natural part of the aging process and are safe to eat. In fact, they are a sign that your cheese is well-aged and will be extra delicious. These white spots are commonly called "cheese crystals" or "flavor crystals", and they are a desirable trait in aged cheeses.
Cheese crystals are usually either tyrosine crystals or calcium lactate crystals, and they can appear simultaneously in some cheeses. Tyrosine crystals are firmer and brighter white, usually found on the interior of the cheese. Calcium lactate crystals, on the other hand, can be found on the surface or interior of the cheese. They are softer and less crunchy and are most commonly found on aged cheddars. These crystals can sometimes look like a thin layer of white mold, but they are not harmful.
How can you tell the difference between crystals and mold? The texture is the biggest indicator. Crystals are hard and crunchy, while mold is soft. Additionally, molds usually grow on the outside of cheese first, so if you notice white spots on the inside of the cheese, it is more likely to be crystals.
So, the next time you see those little white spots on your cheddar cheese, don't throw it away! Rejoice, because you've got yourself a well-aged, delicious treat.

Cheese crystals
If you've ever looked at a piece of cheddar cheese and noticed white spots, you may have worried that it was mould and that the cheese had gone bad. However, these white spots are actually "cheese crystals" and are a good sign!
Both types of crystals are formed during the ageing process. Bacteria break down the lactose in the cheese into lactic acid, which then combines with the calcium present in the cheese to form crystals. These crystals can also be made up of amino acids, the building blocks of protein. The crunchy bits you may notice are mostly made up of tyrosine and leucine, two types of amino acids.
So, if you see white spots on your cheddar cheese, don't worry! It's simply a sign that your cheese is nicely aged and is bound to be delicious.

Calcium lactate crystals
The white spots on cheddar cheese are likely to be calcium lactate crystals. These are not a cause for concern and are a natural part of the ageing process of cheese. In fact, their presence indicates that you have a well-aged cheese that is bound to taste delicious!
While calcium lactate crystals are most commonly found on aged cheddar, they may also be present on other cheeses such as Parmesan and Gouda. They are usually soft and less crunchy than other types of crystals, and can sometimes look like a thin layer of white mould on the outside of the cheese. However, they are entirely safe to eat and are a desirable trait in aged cheeses, adding a slight and pleasant crunchiness to the texture.
The white spots on cheddar cheese are not mould, which typically grows on the outside of the cheese first and feels soft to the touch. If you notice white specks on the inside of the cheese as well, it is more likely to be crystals, which will feel hard and crunchy. So next time you see those little white spots on your cheddar, don't throw it away! They are a sign of a well-aged cheese that is safe to eat and will add a unique textural contrast to your dining experience.

Tyrosine crystals
The white spots on cheddar cheese are tyrosine crystals, a type of amino acid and one of the building blocks of protein. These crystals are firmer and have a brighter white color. They are usually found on the interior of the cheese, although they can sometimes be found on the surface as well.
While some people may mistake these crystals for mold, there are a few key differences. Firstly, mold will usually grow on the outside of the cheese first, while crystals can be found on the inside or the outside. Secondly, mold is soft, while crystals are hard and crunchy.
These tyrosine crystals add a slight and pleasant crunchiness to the cheese, which is considered a desirable trait in aged cheeses. They are safe to eat and indicate that the cheese is of good quality.
So, if you see those little white spots in your cheddar cheese, don't worry! They are a natural part of the aging process and are perfectly safe to enjoy.

How to differentiate crystals from mould
White spots on cheddar cheese can be crystals or mould. Crystals are usually hard, coarse to the touch, and engrained in the cheese, whereas mould is soft and often a raised mass on the surface.
Crystals are a sign that your cheese is well-aged and has a strong flavour. They are usually found on the inside and outside of the cheese, whereas mould is usually only on the surface. If you scrape the surface of the cheese with a knife and the white part flakes off, it is probably calcium lactate crystals.
Calcium lactate crystals are formed when lactic acid interacts with the cheese's calcium. They are commonly found on hard cheeses like cheddar, aged gouda, and gruyere. They can appear as a smear across the surface of the cheese or as distinct specks.
Tyrosine crystals are another type of cheese crystal, often found in aged Italian, Dutch, and Swiss-style cheeses. Leucine crystals are similar but have a more diffused, smear-like appearance. Both types of crystals may be found in goudas, Alpine-style (Swiss) cheeses, and Grana-style cheeses.
