  • Profiling with the Rossa Hand Espresso

    Hello everyone. I would like to introduce the Rossa Hand Espresso. It has been around for a while now, but its partner the Rosco Hand Grinder has just been released. Further information can be found at http://www.portaspresso.com/

    It was originally designed for portability, but I can assure everyone that it offers much more than that. In the past 6 months or so, I have been focusing on pressure profiling with the device, and wow, I wish I had discovered that technique sooner! I know many people think that pressure profiling is just a gimmick and offers no real benefit, but I know for a fact that that is not the case. I profile every shot, and Ive discovered that different coffees (the ones Ive tried so far anyway) require different profiles to produce their best results. In my opinion, not being able to profile is like driving a car that is stuck in one gear, and Im sure that most good espresso machines will have some form of profiling capability in the future.

    I intend to post further information and details about my profiling experimentation, but at this point, I just want to highlight that the Rossa Hand Espresso offers a lot more than just portability; it is a very effective hand pressure profiling device.

    Anyway, feel free to ask questions, and I hope to hear from others who have also experimented with profiling. I think there is much to learn.

    The following link will take you to the You-tube video which shows the Rossas basic operation. You probably cant tell, but this shot was profiled. The pre-infusion and pressure build-up was timed to suit the coffee used, and the pressure was reduced just after half way through extraction. I tried to explain what I was doing during the shot, but the words got a bit muddled because I was focusing on the pressure as opposed to what I was saying.

    Re: Profiling with the Rossa Hand Espresso

    Well, I guess Im a little surprised, and disappointed maybe, that not a single reply has been made to this thread. So a new Australian manufacturer has created something unique, that is clearly constructed very, very well, with a youtube clip that shows a fairly impressive LOOKING espresso shot, offering high quality espresso and complete portability as well as a complementary system of espresso maker and grinder and NOT SINGLE PERSON has shown any interest?

    Well I am interested in hearing more about the profiling concept. Like anyone I need independant proof that the product is good before I buy into it, but it looks the goods so far. Maybe you need to work hard on getting some quality reviews out into the public domain before the public interest picks up.

    Regards

      An independent review should be posted soon, and I will leave it to him to make his intentions known.

      I’m also a little surprised that people on a forum like this would not ask a few questions. I understand that people won’t believe a thing I write, because every manufacturer seems to claim that their machine or device is fantastic, so it is fair for people to think I’m no different. If you guys actually knew how good the coffee made with this device is, I would never be able to keep up with demand. I don’t think it is a device for everyone, but for those who want the best coffee, this little baby is a gift from heaven. Perhaps I should’ve made it look more elaborate and put a higher price on it!

      I understand that not everyone wants a manual device, or even cares as much as I do about the quality of coffee they drink, but I was hoping to start a discussion about profiling; hence the title of this topic. Maybe this discussion should be moved to another area on the site. I also realise that few people have experienced profiling firsthand, because there are few machines out there with profiling capability. Nonetheless, I think all good machines will eventually have this feature. It might be a myth to some and too complex to others, but I know for a fact that the results are amazing.

      To be honest, I knew nothing about profiling when I first designed the Rossa, but once I became aware of the technique, I immediately realised that my invention offered much more than just portability. As my understanding and technique developed, I found that I needed more control over the Rossa than my original designed offered, so I tweaked the design a little to provide the control I needed. The changes also made it easier to use.

      So as I wrote, I’m hoping to start a discussion about profiling, and I would like to learn what the collective group knows about the technique. If people are interested, I will post what I have learned so far. Any decent manual machine should be able to profile, so the information and techniques should apply equally to all.

      So is there anyone out there with profiling experience on a manual device, or profiling in general?

          Hi,

          How is the shot compare to lever and pump machine?

          Anywhere in Brisbane or Melbourne that I could see some demonstration?

          I am really interested in its portability and shot quality, but like everyone else, not sure want to be a guinea pig.
