Exactly how you would expect; both under and over extracted at anywhere between 19-21% extraction. Over 21%, undrinkable, but I would expect that out of this type of blend and roast. It probably did its best for me at 19% and below as nice lazy updosed ristrettos but portions of the profile were then extremely under, puckeringly under. I would have guessed solid and forgiving for this bean and roast with solid mouth feel.
For the person who got a good bag. My congrats, a balanced comment on the real taste of this coffee is welcome. This is my 3rd similar bag in a row from blue bottle and poor flavor experiences before that.
Maybe I'm just no longer a blend person. I hope not...
To the other comment. The photo isn't random but I picked the beans all off the top of the hopper quickly and easily and there were many more examples. I set up as a coffee wheel to further contrast. But it isn't far from representative of the average. It was a sad sack of tears (I had no backup in the on deck).
I thought that blends should be blended from coffees that extract similarly (Perger), this makes sense to me. I can only comment that my 4-6 weeks on Bluebottle was a total fail, that honestly became a great learning experience tho. Look at your beans! Another angle of the wood mulch.
