I’m using this recently acquired bad boy here to brew my espresso (bought it for $40 used), after having used a nespresso capsule machine for a few years.
I have a bit of a hard time brewing a consistent Espresso with it though. Often the flow is absolutely terrible, and barely any water flows through the coffee, despite using the exact same amount of beans. I measure on a scale with 0.01g accuracy, not my regular kitchen weight.
Is the grind consistency really what’s messing it up for me? I’m using one of those “blender style” grinders at the moment and it has served me just fine for French press in the past, but I know they’re terrible for controlling the fineness of the grind.
I use a Kingrinder K4 which, when I bought it 4-6 months ago was the cheapest espresso capable hand grinder I could find. It only takes about a minute to grind 18g for a shot and I normally make 2-4 shots a day. They have cheaper grinders, such as the K0 but I’m not sure if they’d be consistent enough or have a sufficient granularity of adjustment to dial in an espresso.
