I purchased this coffee to replace my Lavazza because Lavazza quality has been inconsistent. Upon opening, I noticed no date on the package... concerning. I tuned my Vario grinder to ensure the correct grind for this new bean. I pulled a shot of espresso (I have an Andreja Premium from QuickMill)... Horrible. I adjusted the grind three more times with as many shots. The shots were consistently watery, bitter, and, quite frankly, embarrassing. DO NOT purchase this product. I will use these beans to pull throw-away shots after cleaning my grinder and espresso machine... that's all they are good for.
Negative
