You may not recognize this week's WTF item, but chances are you've enjoyed it (probably this morning!) It's green coffee beans. No, that's not some exotic strain of coffee that brews up a green cuppa joe... This is actually what all coffee looks like before it's roasted. Check out my behind-the-scenes look at Oslo Coffee Roasters' roasteria where they store barrels of these green gems for roasting—a fragrant process that transforms these green beans into the dark, oily, aromatic beans we use to brew.
PS: If you get your hands on some green beans, you can roast them at home. Try this Lifehacker method for roasting your own coffee—in a popcorn popper!
