Had to throw out a 320g bag of the new blend out, watery weak flavour with a metalic aftertaste. Im not sure who your taste testers are, but obviously not those who are already customers.
Why not keeps the same blend and create another if you think others may like the taste.
Since you also reduced the bag size to 320g from 350, i suspect cost cutting is the cause of this "Improved flavour". Dont worry about the sediment in the bottom, I doubt anyone will get through enough of the cup to see it.
I tried to get used to it but after about 10 cups, I had to throw it out. Very dissapointed and a colossal waste of money.
