    My point is, I will prove that the Rossa can make the same quality as a portable solution.
    Any Rossa owner willing to take some time to post some user-videos? I've exhausted Ross's video and they're very nice & educational. But some videos from the actual owners would probably be more interesting & maybe relevant (as in new owner using new equipment).

      I just demoed the PG AIR brass model with Ross from portaspresso yesterday, and ive gotta say wow, it makes a very nice espresso, doing a quick demo with old home roasted beans and a kettle on a gas cartridge campstove by the side of the road, i had a top notch drink with tonnes of flavour, sweetness and crema. Almost as good as my commercial lever makes

        Since I've got the Rossa Air and very happy with it, I've posted quite a few videos on the youtube. Just search for Rossa PG.

        By the way, Is there anyone in Melbourne kind enough with Rossa HC model? I am curious to try and compare between the two(Air vs HC), but doesn't have the cream to spend on another set. :P Just shoot me a pm if you're around.

          Any new users out there? What do you own?

          I had a Porlex grinder for more than 1 year. I've received the Rosco mini 1 month ago. It makes a huge difference. I made my best espresso so far last weekend on 6 bar. Rosco mini setting is at 0.5 mm and seems to be optimal for freshly ground coffee. For store-bought coffee is not enough.

            New users... do you reckon it is feasible to use the Rossa with the handshaft (not the bicycle pump) at work ? Would love to crank out a shot at my desk every morning...but wondering if it would be too fiddly to do at my desk.

              I own the Air Alu version. I will get the brass one also and sell the alu. I don't have the HC, but I've rea the manual. It would be messy to do it at your desk. Of course if you have some extra space, you could try. Both are kinda messy. I always clean everything, even the grinder exit with a brush, so there always some leftover coffee particles. You need water kettle also.
              I believe if you would pre-charge the air cylinder at home, that would be less messy at the office than the HC.

                Thanks for the reply, never thought of pre-charging with the pump, that would work well actually if I took a pre-tamped basket in and pulled the shot straight away...

                  The biggest mess is the purged water after the preheating. Also, you need to let the device finish after you've completed the shot. Having a sink is always preferable I'd say.

                    Why are you selling the alu for the brass?

                      I can't speak for beo1329, but as an owner of both an alloy and brass air Portaspresso, I think I know why.
                      The brass one has all the signs of being a machine to hand on to your kids, while the alloy one seems less permanent somehow.

                      I use my alloy one for motorcycle touring, weight being an issue and it does a fine job, but last trip it developed a leak on the valve of the air chamber, made obvious by the bobbles seen raising up through the pre heat water, it eventually came good again, towards the end of the two week trip, but I was concerned. My imagined fix is to call Ross, and get a couple of extra brass pressure chambers, they will fit either, and make the two cup turnaround of the machine much quicker, not having to recharge a hot pressure cylinder.

                      I use my brass one on board my ship, while at work, as weight isn't an issue there. I can recharge the pressure chamber and it will keep its pressure seemingly for ever, don't know about the alloy one, but I now don't trust it, after the leak.

                      So the alloy body, mini Rosco grinder, two brass pressure cylinders and my jetboil will do me for my camping.

                        Thank you for your reply.

                        I've had the air bubbles bobbing up issue, but it doesnt effect the coffee and it's since gone away.

                        I think the brass model is a better choice in the long run. My alu one is fairly well aged and looks dirty. It's impossible to keep clean. Also, using a scourer to clean alu isn't the best idea.

                        Again, the coffee is still great so I'm not worried.

                          Bubbling during preheat is normal. However is less noticeable on the brass version, because brass has less thermal expansion.
                          If you see a lot of bubbling during preheat, you can slightly tighten the valve, but make sure you never overdo it.
                          This instruction came from Ross.
