Moved forty miles and my coffee broke overnight. Same beans, same grinder, same recipe. Spent two months on the grinder before somebody mentioned water.

The thing that makes this hard to diagnose is that it is invisible and it affects everything at once, so it reads as "I have got worse" rather than "one variable changed".

Read the mineral content on the bottle rather than assuming. The cheapest one on the shelf is often the right one.
