Brill cheese was a creamy, pale green cheese.

In 2371, in response to Ensign Ashmore's request for macaroni and cheese, Neelix made brill cheese from schplict (grakel milk), which the USS Voyager crew had obtained on the planet Napinne the week before. However, the bacterial cultures he used accidentally infected the ship's bio-neural gel packs, causing major malfunctions. (VOY: "Learning Curve")
