Do people drink sheep milk?

Yes, but it’s a sign of a la-aa-aa-aa-ctation fetish.

I can remember as a youth we had goats. The milk was terrible, It was even worse than commodity powdered milk, we called that Gorilla milk.
Milk taste is reflected a lot by what the mammal eats. Our goat milk always tasted grassy.
As to the perception some speak about. If someone doesn’t like it. Hey thats there own business. Doesn’t matter why.
I remember my Dad trying to get Grandma (mother-in-law) to drink the goats milk, she didn’t want to.
You guessed it, he put some in a regular bovine milk container and She never talked to him again. He got what he deserved.
The local dairy had a milk stand at the County fair, and all you could drink for $0.10
That late in the summer we were ready for that treat after a summer of Gorilla & Goat(grass) milk and combinations of both. YUK!
I use Gorilla (carnation) today for hunting and camping. The grand children think it is a treat! It is better than the stuff from 50 years ago.
