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.
