You not a coffee enthusiast if you haven't hacked your machine :-). I did the OPV mod to get that 9 bar pressure on my machine. Yes I have steered the conversation to espresso. The downside is it wastes water (pressure is reduced by diverting water to waste). But not having it jam the puck with too much pressure is worth it!
- lostlogin 3y agoI like a high pressure extraction. If I tamp my espresso too hard, the machine has enough power to unscrew the portafilter and blast it off, punishing me for my sins. Faema E-61 Legend. The best machine ever.
- mortos 3y agoOPVs typically divert the water back into the water tank of the machine. That's at least how it worked in my machine. The only machine that immediately comes to mind that wastes water like that is the GS3 MP from LA Marzocco for $7,500. The GS3 uses a valve at the group head, after the boiler, rather than an OPV which is normally before the boiler.
