looking for the name of a movie about the arctic

I saw a movie when I was a young kid ... it would have been made in the early 80s or maybe late 70s probably.

It was (I think) about some early (maybe 19th or early 20th century?) white arctic explorers who encounter some Inuit (I don't remember much.)

The main scene I remember is when some of the explorers find some wild berries and they ferment it into alcohol. Everyone gets drunk and there is a beautiful bit of Inuit throat singing.

Sorry I don't have more info, but it was ages ago.

Thanks for anyone who remembers this
