what does green cheese mean

“Green cheese” usually does not mean cheese that is literally green in color – it’s a traditional term with a couple of related meanings and one famous idiom.

Core meaning

• Historically, “green cheese” means new, fresh, not‑yet‑aged cheese. The “green” refers to its newness or “young” state, not the color.

• In older English usage, it’s cheese where the whey hasn’t been fully pressed out yet , so it’s moist, soft, and under‑ripened.

Other literal uses

• The term can also be used for soft cheese made from skim milk or whey , or for cheese colored green with herbs like sage (for example, sage cheese / Sage Derby).

• There are a few cheeses that really are green or green‑marbled (e.g., Cherni Vit, Sage Derby, Schabziger), but those are specific products, not the original meaning of “green cheese.”

Idiom: “The moon is made of green cheese”

• In idioms and jokes, “green cheese” shows up in the phrase “the moon is made of green cheese” , a deliberately absurd old saying.

• In that idiom, the idea is: only a very gullible person would believe something so obviously false , so the phrase became a way to talk about credulity and critical thinking in a playful way.

Quick recap

• Literal meaning: fresh, young, not‑aged cheese (often white, not green).

• Extended literal meaning: sometimes soft whey/skim‑milk cheese or herb‑tinted cheese.

• Figurative meaning (idiom): part of the humorous phrase “the moon is made of green cheese,” used to illustrate believing impossible things.
