Finally got around to buying a scale and has confirmed my suspicions that my extract is too fast. I'm using Pact coffee, pre-ground to 'fine' for espresso use.
This morning, aiming for a 2:1 ratio, a 22g dose yielded 45g in around 16 seconds - I understand that I should be in the 20-30 second bracket.
My thinking is to tamp with more pressure to slow the extraction. After that, I'm really not sure...
Do you have a pressurised portafilter or regular? With a regular one there's really no way around grinding your own beans with a grinder you can fine-tune. A small change in grind can have a big effect on extraction time.
