The Science Behind the Squeak


Fresh cheese curds are a delightful snack loved by many for their unique texture and squeaky sound when bitten into. But have you ever wondered why fresh cheese curds squeak? The answer lies in the fascinating science of cheese-making and the properties of curds. In this blog post, we'll delve into the intriguing world of cheese curds and explain the factors that contribute to that delightful squeak. We'll also uncover a secret trick to revive the squeakiness of your curds.

The Basics of Cheese Curds

Before we get into the science of the squeak, let's briefly explore what cheese curds are. Cheese curds are the young, moist, and springy chunks of cheese that form during the cheese-making process. They are typically made from fresh cow's milk, though other types of milk can be used as well. Cheese curds are often a byproduct of the cheese-making process when curdled milk separates into solids (curds) and liquid (whey).

The Squeak: A Unique Phenomenon

The signature squeak of fresh cheese curds is what sets them apart from other cheese varieties. When you bite into a fresh curd, it produces a high-pitched squeaking sound that can be heard and felt. This distinctive squeak is a result of several factors.

  • Moisture Content - Fresh cheese curds have a relatively high moisture content compared to aged cheeses. This moisture is trapped within the curds, creating a cushioning effect as you bite into them. The release of this trapped moisture during chewing contributes to the squeak.
  • Protein Structure - One of the key proteins in cheese is called casein, and it plays a significant role in cheese curd texture. In fresh cheese curds, the casein proteins are in a more elastic and flexible state due to their youth. As you bite down on the curd, these proteins rub against each other, producing friction and sound – the squeak.
  • Temperature - Temperature also plays a role in the squeak. Fresh cheese curds are best enjoyed at room temperature or slightly warm. When they are too cold, the proteins become less flexible, and the squeak diminishes. On the other hand, if they're too warm, the curds become soft and lose their characteristic texture.

Reviving the Squeak

The delightful squeak of fresh cheese curds is somewhat ephemeral. It tends to diminish over time as the curds lose moisture and the proteins continue to change. However, there's a secret trick to revive the squeakiness of your curds. If you find that your curds have lost their signature sound, simply microwave them for 3-5 seconds. This brief burst of heat can restore some of the lost moisture and temporarily bring back the squeak.


The science behind the squeak of fresh cheese curds is a captivating blend of moisture content, protein structure, and temperature. These factors come together to create a sensory experience that cheese enthusiasts find irresistible. So, the next time you indulge in a handful of fresh Amish cheese curds from Simply Cheese and hear that satisfying squeak, you'll have a deeper appreciation for the intricate science that makes it all happen. Enjoy the squeak while it lasts, and remember the microwave trick to bring it back to life whenever needed!
