Just one more quote from the site.

: Most importantly, the Tarahumara believe tesgüino is a divine gift. It must be consumed in order to praise God, to compensate for the moral shortcomings of others, and to ensure existence itself.

It was also stated that God gave the Rarămuri beer as a consolation prize because God lost a bet with the devil and that is why the white men are rich and the Rarămuri are poor.
