Trouble with uneven volumes from a dual spout?
No doubt most people flush their portafilter in the morning before the first coffee. I haven't been, and i often have an issue with uneven volumes from the dual spout, in that the coffee would only drip from one side for a while until the flow rate increased enough for it to pour from the other side. We usually only have 1 coffee before leaving the house, however this morning i made a second coffee and realised on the 2nd round the coffee poured from both spouts immediately and at the same volume.
So if anyone has that issue, run some water through not just to flush the group head, but to ensure there's moisture in the spouts to allow the coffee to flow properly from both sides.
Small thing i know, but always good to have an "ah ha" moment.
Great advice! Could also be as a result of an uneven tamp/ uneven extraction or even an unlevel coffee machine!
