> Here's a quote from a post on the CoffeeGeek.com forum: <Snip> Question: what does a nonpressurized portafilter do for the coffee brewing? Doesn't the pressurized PF help it get to the right temp and pressure? I'm on my second Barista (TM) machine-- the first one lasted 6 years and with a valve change, new head gasket, and new pickup hose it could probably do a few more. I know its not the best machine out there but when they go on sale/clearance they are a very good deal. When my original portafilter started cracking at the handle I checked online for prices and then called *$; *$ was cheaper by $20. But they probably don't have a nonpressurized one.
Kevin, It has been a few years since I retired my *$ Barista, so things may have changed. The service I received from them was absolutely exemplary, the 'Barista' had just changed from the colored enameled housings to the newer rounded version (available in Stainless Steel). I had purchased a second, new style, machine for home and was taking the older unit on the road with me. I called their service folks and asked about the non-pressurized PF, was told they would ship it with my order for spare group gaskets and odds n' ends. When I received the order (free overnight express) there were two non-pressurized PF's included (no-charge). During the seven or eight years during which I owned one or two of these machines, I was never left with less than a warm n' fuzzy feeling when dealing with their service folks. Mike (just plain)
"...what does a nonpressurized portafilter do for the coffee brewing? Doesn't the pressurized PF help it get to the right temp and pressure?" Yes, but it's like riding a bike with training wheels... Take the plastic pressurizing diaphragm out of the bottom of the PF and save your money. Just one #1 Phillips screw in my Capresso got rid of it- then there's my total lack of knowledge and experience. I don't think I'm gaining much trying to perfect shots on the little machine, but no eagles airborne right now. I suspect the pump is a weakfish, to deflect some blame. Karen, the Celtic Critic, approves most of my shots. Ha! Those are the ones I have her try out. Cheers -RayO, aka Opa! Live and learn. I know how Not to brew espresso drinks...

PF merely creates more resistance and forces air through the grounds, producing a short-lived fake crema and making it impossible for you to meaningfully impact on the quality by manipulating grind and tamp. A non-press. PF will not in and of itself "do" anything for the coffee--but it enables YOU to do so by controlling those variable parameters (skills you will need when you move up to a real machine or seek work as a barista).
