@Will2Power @Evil_Bender @Shadowbroker2135 @Beefki @Vashna @Wormwood McDonald's coffee is sourced mainly from Brazillian Arabica
It's not designed to taste "good"; it's designed to taste "good enough" for the most people possible.

In brazil they use tons of pesticides on the coffee
Then they ship it to california to be ultra processed
Then it goes to a distributor and sits in a warehouse for a while
Then it goes to a local supplier and sits in a warehouse for a while
(by this time, the coffee is already stale by the way)
Then it goes to the store & sits on a shelf for a while
Then they make it in machines they never clean
Then a brownoid serves it to you
