My favourite is the French Le Gall Grand Cru organic and unpasteurised butters:

From their web-site

"Grand Cru butters

These butters are produced exclusively using unpasteurised raw creams.

They are more fragile and do not keep as long. These are the most flavoursome butters.

Churned butter made with raw milk undergoes only a little heat treatment.

This gives it an authentic taste that is even more pronounced than a traditional churn"
