Hi all,
I'm a barista in a small coffee shop, and have recently been getting an excess of grinds in my shots. I've searched around and haven't discovered what it would be as yet.
It is not:
- Grinds on the bottom of the group handle spouts - they are rinsed clean before every shot I pull.
- Too fine a grind - we use a spring loaded tamp that ensures the correct 30lbs of pressure is exerted. A full shot takes 27 seconds. Shots taste right, a courser grind results in under extraction and too much volume
- Pretty confident it shouldn't be the filter baskets as they are 6 months old and supplied with the machine. I'm hoping they aren't this bad anyway.
So other ideas? After one shot around the shower screen seems excessively dirty.
