Duetto V3 Second Look

Second Look :: Izzo Duetto V3 Six Month Review

It’s hard to believe the new Izzo Alex Duetto V3 has been out since late November, but believe it!  Since we’ve had about 6 months to use and evaluate this new version, we thought it was time to give you a quick update with respect to its build quality and performance out in the field.

No big surprises here, the V3 continues Izzo’s tradition of great Italian build (I know, sometimes an oxymoron), sturdiness, and curb appeal in a pro-sumer machine. After some heavy holiday sales and use, I took some time to listen to what a few of our early adopters had to say:

By and large everyone is saying the V3 is superb so far.  Very few warranty issues, very stabile brew water temperature control, and very easy to use.  So really, nothing has changed!  Which jives with what we said 6 months ago, that this new version is mostly about cosmetic changes. Our showroom Duetto sees much use during our barista classes, where it pulls shot after shot for 2 hours straight without missing a beat.  We have had zero problems with our unit, no adjustments to brew pressure, nothing.

But this isn’t just a fluff piece…

The most common comment that could be construed as a negative is that the Duetto V3 is just plain heavy.  It has large boilers, and weighing in at about 92lbs with water, it can be hard to move around to add water, especially if the machine lives underneath your cabinets.  The other comment is that the Duetto must be plumbed-in to get pre-infusion.  These issues are connected of course, and have led me to advise folks to plumb this machine in, thus saving yourself from having to move it around to put water in the not-so-easy-to access internal water tank, and to reap the benefits of pre-infusion.

Something else I’ve heard (and experienced) is that with the steam boiler turned off, the coffee boiler has a hard time maintaining a steady temperature for your shots.  This is because in the Duetto the steam boiler actually pre-heats the water for the coffee boiler.  This saves a lot of recovery time when the machine sees heavy use, but is a bit of a bummer for those who want a shot brewer.  I recommend simply that you don’t turn off the steam boiler.  It is very well insulated, and really doesn’t take much power to keep it at the correct temperature.  Your espresso will thank you.

The one thing we’d change on the V3 is the insulated steam wand.  In my experience, the insulation in smaller non-commercial machines such as the Duetto slows down milk steaming and does not yield great micro-foam.  So Ken (our service tech) and I just took the insulation out and added a rubber grip to the elbow of the wand.  The result is a wonderful, easy to use and to control steam function that is more powerful without the insulation.  We would definitely recommend this quick customization.  Just unscrew the steam tip and pull the insulated hose out with a pair of needle-nose pliers.  I think it took us slightly less than a minute, and is well worth the effort! (Note: This modification works on machines with large steam boilers like the Duetto and La Marzocco GS/3; in our tests the Rocket R58 and QM67 boilers do not work well without the steam wand insulation).

    I also pretty quickly pulled the insulation out of the steam wand, and boy what a difference it made. This is a great machine and overall am very pleased with it. I had a hard time getting 18+ gram double shots with the stock basket so I ordered the VST 20g and that was able to get me the higher amount. The only other thing I noticed was that the temperature sometimes overshoots the target by 3-5 degrees. I assume this is probably easily fixable with a change in the PID settings but I don’t know where to start. Any ideas? Overall I am 100% satisfied with the machine and wouldn’t have bought anything else now that I’ve been using it for 3 months. You guys were amazing to work with and I appreciate the phone support and help getting it all plumbed in. =)

    Chris, do you have any idea if you can simply re-insert the insulation back into the steam wand?  Thanks.

    Thanks for the kind words Geoff. That is a fairly normal temperature swing. I would actually avoid trying to adjust the PID offset unless you have a Scace sitting around.

    It is possible to push the insulation back in, but it may be easier to remove the steam wand to confirm that the seal has been made.

    If you pull out the tubing where do you get the plastic “handle” to put on to the wand?

    Give us a call. We have them in stock in the showroom.

    Would you explain why you cannot preinfuse unless plumbed?  What makes it different that a Rocket or the QuickMill in this respect?  Thanks!

  • Written by: Kevin Haugen

    Any traditional E61 machine (Rocket and QuickMill included) must be plumbed in order to pre-infuse properly. While you may see a pre-infusion of sorts unplumbed, it will result in a siphon lock in the brew group and could potentially damage it.

    Dear Kevin,

    Is there an insulation of the brew boiler in the Alex Duetto III which you sell? Because the European version of AD III is being shipped with insulated brew boiler. Also I have had conversation with Izzo Technical Department and they assured me that the settings P=1.3, I=0,06 and d=1,5 are the same for US and European Market?! Which is strange to me because the heating elements for USA and Europe are different. What do you think about this?

    Thanks and regards,

    Hi Petar,

    The boilers are in fact insulated. 220v machines should have faster warmup and reheat, but we try not to think about it too much because we’re only able to get the 110v machines in this country 🙂
    As far as the PID settings are concerned, we feel that Italians do a fantastic job and they’ve kept our Duetto 2 and 3 owners very happy.
