I was talking with an ex-manager of a Starbucks store recently and as he was telling me how much he hated Starbucks, which I hear often from ex-employees, he also told me how they burn their espresso roast and add oil to the beans. I have never heard of adding oil to coffee beans and can’t understand what effect this has on the product. I can find nothing online documenting this, I am not saying he is lying, but I would like to know why this is done. Any employees of Starbucks (ex or otherwise) or anyone else that might know the answer?

Hmmm, I don’t know but I know that I can’t drink their coffee because it gives me massive stomach pains.
