My coffee tastes too bitter, sour, or strong.Updated 23 days ago

• Too bitter - over-extracted. Try a coarser grind, less coffee, or shorter contact time.

• Too sour - under-extracted. Try a finer grind, more coffee, or longer contact time.

• Too strong - use more water or less coffee.

Also worth checking: filtered water makes up 98% of your cup, so water quality makes a real difference. Make sure your machine is also clean and descaled.

We've put together detailed guides for every brewing method on our brewing guides page and it's the best place to dial in your perfect cup. Our coffee blog also has plenty of tips if you want to go further.
