Macaroni and cheese, grilled cheese, cheeseburgers… isn’t cheese WONDERful? We think it is. Well, most of the time, it is.
To make cheese, milk is first heated to kill any harmful bacteria. After the milk cools, it is put into large containers.
After the starter culture, rennet is added. rennet contains an enzyme that makes the proteins in the milk (called "casein") coagulate. This makes the milk separate into solids (curds) and liquids (whey).
The whey is then drained off, leaving only the curds behind. The curds will then begin to clump together in a process called "cheddaring." Salt is often added at this point to improve taste and remove additional moisture.
The salted curds are eventually pressed into blocks and cooled until they form solid blocks. The solid blocks of cheese are then stored for several weeks to several months to allow them to ripen until they are ready to eat.
Different types of cheeses are made by using different starter cultures or slightly varying the steps of the cheese-making process. For example, mozzarella cheese is kneaded like bread dough to give it its signature stretchy texture.
So why do some cheeses stink and some have hardly any smell at all? The answer lies mainly in the starter culture used to make the cheese.
For example, some bacteria give cheese a mushroom flavor and a particularly stinky odor. Examples of such cheeses include Brie and Camembert.
Other factors that can make cheeses especially stinky are aging and washing. Some cheeses are aged for many months. The extra aging often intensifies the cheese’s aroma.
The rinds (edges of blocks) of cheeses are sometimes washed often as the cheeses ripen to keep them moist. Depending on what liquid is used — brandy, port, beer and salt water are commonly used — the cheese may develop certain flavors and smells over time with repeated washings.
If you’re wondering what the stinkiest cheeses in the world are, there are several that are known for their particularly pungent aromas. Vieux Boulogne is known for being stinky because its rind is brushed with beer while it ages.
Another cheese — Époisses de Bourgogne — is so stinky that it has actually been banned from being carried on public transportation in France where it's made!
Perhaps the most famous stinky cheese ever, though, is Limburger. Its stinky reputation is well-documented in many Saturday morning cartoons, as well as old television classics like The Three Stooges and The Little Rascals.
Some believe Limburger cheese smells like feet, which might make sense. The bacterium used to create Limburger cheese is Brevibacterium linens, which is the same bacteria responsible for human body odor!
