eli5: How do large scale coffee roasters coax the same flavors out of beans in each batch?

526 views

As far as I know, roasting the beans produces the flavors, so how do companies like Starbucks ensure every batch of beans they roast produces “Verona” and another batch produces “Pike Place”? Do they add flavorings? Different bean sources? Roasting process factors?

It just blows my mind that Starbucks, Dunkin, McDonalds, etc. can all produce such different coffee from the (same?) coffee beans.

If they just put different names on the same beans, would anyone notice? Can people identify different Starbuck’s blends in a blind taste test?
