Why Does Emmental Cheese Have Holes?

Buckle up, cheese enthusiasts, because today we're diving into the gaping, cheesy voids in one of the most iconic cheeses in the world—Emmental! You might know it better as 'Swiss cheese,' but if you're fancy like me, we go by the name Emmental. And what could be more fascinating than discussing the mysterious holes, or as the cool cheese scientists call them, 'eyes,' that make Emmental a standout in the cheese aisle? Well, maybe discussing why my cat thinks I'm discussing complex astrophysics every time I talk about cheese science, but I digress.

Okay, let's start with a little history lesson to spice things up. Emmental cheese dates back to the early 13th century in, you guessed it, the Emmental region of Switzerland. Picture it: rolling Swiss hills, cows grazing peacefully, and alpine villagers perfecting their cheese-making art. It’s like a Swiss postcard, but with more lactose. The presence of holes has always been a notable feature, but it wasn’t until the 19th century that we started some real scientific snooping.

You see, cheese-making back then wasn't exactly a precision game. Microbial hitchhikers stowed away in the milk. The primary suspects for the holes we adore are three types of bacteria: Streptococcus thermophilus, Lactobacillus helveticus, and Propionibacterium freudenreichii. Try saying that five times fast! These bacterial buddies work together in harmony, breaking down the lactic acid in the cheese and releasing carbon dioxide gas. The gas forms bubbles, and voila, you have those beautiful, iconic holes.

Back in the day, cheesemakers believed that the holes were imperfections. Can you imagine that? Imperfections! It’s like saying a cake has 'too much chocolate.' Fortunately, some blessed soul figured out that these so-called imperfections could be a defining feature if marketed correctly. And there you have it, the holes became part of Emmental’s charm.

And while we're talking bacteria, here's a cheeky little cheese fact for you: The size and number of holes can tell you a lot about the cheese itself. Larger holes often mean a stronger flavor, while smaller, more numerous holes might indicate a milder taste. Now you can impress your friends by decoding Emmental like some kind of cheese mystic!

But wait, there’s more! Have you ever wondered why sometimes you barely see holes in your slice of Emmental? In the early 2000s, cheese scientists were stumped! The answer lay in the modernization of dairy farming. In the old days, hay particles would fall into the milk and act as nucleation sites for the gas bubbles. With modern milking techniques being much cleaner, there was less hay, fewer bubbles, and thus, fewer holes. Who knew cleanliness could rob our cheese of its holes?

Now, let’s bring this all home with a fun cheese quiz: Which medieval Swiss village claimed Emmental was a divine gift from dairy gods? If you guessed 'All of them,' you’re close enough!

So the next time you’re enjoying a slice of Emmental, take a moment to appreciate the history and science that put those holes there. Consider it a tiny, delicious marvel of cheese engineering.

Stay cheesy, my friends!
