So an update on the Member's Mark House Blend product I've tried using. While the roast and flavor profile is quite good (to my tastes) the quality of the either the handling of or the beans themselves is quite "suspect".
I realize there will always be "chaff" in a bag of beans. But, I am very alarmed at how much of a bag of these MM beans are just chaff. I've now tried them in my Breville grinder, my KA grinder, and now 3 different Baratza grinders (yes 3, FWIW I am looking at "branching" my business model a bit to include high end grinders). Anyway I have an Encore here, a Virtuoso Plus, (both of which are 40mm conical burr units) and now as of yesterday I was able to acquire a very nice Vario W (weight based) grinder with 54mm ceramic flat burrs.
All of these grinders are behaving the exact same way with the MM beans. Very inconsistent grinds because of all the debris and chaff. It seems these pieces of "waste" material simply pass through the grind chamber either untouched by the burrs or not crushed correctly.
Leaving a messy grind that is inconsistent. Looking in the 2 bags I bought, it seems the reason for the cheap price is I think they're sweeping the floor in the roasting chamber and packaging what's left. But, a bag of these is close to 40% broken little bits and pieces not whole beans.
So, the last bag I bought will be the last bag I buy and I will be leaving a review about it with Sam's on why I am making the decision to leave them on the shelf.
I also began noticing this with the Kirkland House Blend but nowhere near this extent. FWIW I have a bag of Kirkland Espresso Blend waiting in the wings. I will see how it fares in this dept.
But, IMO if I pay for a bag of "whole bean" coffee I expect "whole beans" not little busted up bits and pieces
