Why Does Some Cheese Have Holes?

The video explains the unique characteristics of Swiss cheese, particularly its holes, known as 'eyes.' It discusses how these holes are formed by bacteria during the cheese-making process. The video also explores why modern Swiss cheese has fewer holes, attributing this to changes in production methods and the absence of hay, which used to aid in bubble formation. The role of bacteria in cheese making is highlighted, along with a brief mention of other cheese types like mozzarella and cheddar.
