I dont actually drink it, but, i try and keep comments from my Wife on the good side!! She has it as americano not a straight shot.
Best comments seem to be circa 5 seconds pre infusion and 30 35 seconds shot time.
One observation from me is that decaf always looks like its going to run quick but somehow slows during the main shot.
