DavecUK It won’t make drip or filter any worse than all the other grinders with espresso burrs, so you should enjoy it.
I deleted a few lines that would have made my “Not expecting anything spectacular” make more sense.
My wife purchased the coffee from a grocery store. I was surprised to find a date on the bag.
The coffee is as expected, bad. 10 years ago, it was easy for my wife and I to find fresh coffee. Now we have 30 varieties of stale coffee to choose from.
Using looks of grind size to compare to my existing grinder (Ode V1) was not possible. The duo is much more consistent on size.
Edit: 4.3 on the Ode was too sour. Tried to match 4.0 of the Ode. Stopped at 65 on the duo, still finer than the Ode…. Will try 60 tomorrow)
