Automatic coffee machine makes bitter coffee

Coffee from your automatic coffee machine tastes bitter – it’s a matter of adjustment.

You wanted the benefit of an automatic coffee machine but now the coffee tastes bitter? There can be many reasons for this and is no cause to doubt the machine. You know that you can adjust the fineness of the grinder on your machine? It’s a key factor for coffee enjoyment and controls whether the coffee from your automatic coffee machine tastes bitter, watery or simply delicious. The rule of thumb when preparing coffee is that the finer the coffee, the stronger it tastes. That’s because finely ground coffee has a greater surface area than coarsely ground coffee and more coffee substances can be released from the beans. If the coffee from your fully automatic coffee machine tastes bitter, we recommend using a coarser setting on the grinder. If that doesn’t help, it could be that the coffee beans have a particularly strong flavour.
