为什么牛奶是白色的，奶酪却经常是黄色的？当然，奶酪有多种颜色，从淡白色到深黄橙色。以切达干酪为例——它有两种色调。那么哪种颜色的奶酪是“真正的”奶酪呢？
This is a story about a lie that we've been told our whole lives.
It's a story about marketing, economics, science and biology.
And most importantly, It's about why a lot of cheese is orange.
Cheesemaking basically starts here.
I know it seems like we're starting a little bit early on in the process, but hang in there with me.
Animals like cows, buffalo, goats, sheep, they naturally eat grass, which gives them the nutrients they need to produce milk.
And that milk gets turned into cheese.
That is one vascular utter by the way.
In the 12 and 1300s, sheep were often the main producers of milk.
But the catch was that: a sheep can turn, their grass intake into either wool or milk, but not the same amount of both simultaneously.
