Had enough White Knight for now. Switched back to Fresh Roasted Coffee's Organic Drago Blend. Finally getting a good cup. Left a five-star review on their web site and ordered a new supply of it.
@stueytheround I splurged a bit with my order of Drago and got a single 18-count box of Jamaica Blue Mountain. Cost almost as much as a 72-count supply of the Drago coffee!
