    Hi Graham,
    Nope, not a misprint. Here is the text from the Domobar Users Guide:

    Stand by Mode (Heating lamp will glow)
    Aim Steam wand into Drip tray
    Slowly open steam valve
    Press Steam button (ON)
    Wait until steam no longer splatters (Approx 1 minute)
    Close Valve
    Wait till pressure is >2 bar
    Texture milk


    I dont know what temperature that represents, but the water is definitely boiling and the steam pressure is high.

    Greg
    I think there is some confusion here re the specific machine discussed....
    [*] Vibiemme Domobar Levetta (Vashetta) - single 0.7L  boiler machine at circa $1300- just like a sexy albeit much better e-61 based Silvia- The VBM Levetta runs 4 bar boiler pressure or more in milk texture mode as dictated by the pressurestat - You push a button and wait for it to come to pressure and then texture the milk. Higher pressure = more steam and a bonus as the shots have already been pulled and temperature is therefore irrelevant.
    [*]Vibiemme Domobar Super more like $2400+ is a 2.7L boiler HX machine- Ideally runs 1.0-1.2 bar boiler pressure as dictated by pressurestat.

    I thought the initial questions were about the Levetta (Vashetta)  :-?

    It may be that I texture larger quantities of milk than some of you...I nearly always use a 750ml Motta jug for 2 milk coffees in large cups.

    After bleeding the water from the steam wand, I always wait until the pressure gauge has reached 4 bars, no more, then start steaming with the boiler light still on. I found that this gives me the best results. With my machine, the boiler light switches off at about 6 bars indicated.

    As Chris said, Ive found you can steam effectively at almost any pressure.

    No Mark- little need to look at the gauge.

    In the levetta, the gauge shows system pressure only- this has a relationship to group head pressure. I heard that the pressurestat allows the boiler pressure to come up to 4 bar for milk texture- which I guess makes sense. It allows for some extra steam out of a (relatively) small capacity.

    Hey thanks Trev,

    I got excellent results this morning with my one hole. The trick is not to stretch the milk too much, 20-30 degrees as you mentioned, then sink the tip. Oh and go easy opening up the steam valve, especially on small quantities of milk for one latte.

    Will look into doing the mod to the tip myself at some stage. Thanks for the note.

    Cheers
    Javabeen.

    Hi again javabeen,

    Im certain that, given your experience, youd find the VBM 2 hole tip just fine for milk texturing and Im sure they would be available if you were interested...alternatively I believe Coffeeparts stocks a generic 2 hole tip. It may be harder to clean, though, as I think it is smaller than the genuine VBM 2 hole and may not be a flush fit with the rest of the tip assembly.

    Yes 4 hole tip :-( I got mine new from Talk Coffee, didnt know they came with a 2 hole tip. In fact, the VBM website states 4 hole tip on the specs sheet...

    Hi Javabean,

    Quick question...did your Levetta come with a 4 hole tip? I ask this because I understood from ECA Australia that all of the new Levettas were being supplied with a 2 hole tip, as is mine, purchased locally in Adelaide in October 2007.

    Hi Graham,

    I got my Vibiemme Domobar Levetta about 10 weeks ago and can echo Trevs responses:

    1  Quality for money: Excellent. The E62 group is magnificent and the build qaulqity is superb.
    2  Ease of use: Operating the machine is very easy and straight forward once you learn to operate the leaver. I upgraded from a Gaggia machine and really love the lever operation. Keeping it clean is about as painful as any other machine.
    3  quality of coffee shots: Superb as trev said ;-) . The consistency in pulling the shots is amazing, and I reckon its because of the e61 group. I could never go back to a Gaggia or even a Silvia machine.
    4  and what grinder you are using: Mazzer Mini. An amazing grinder that pairs with the VBM very well.
    5  quality of steam: excellent. As Trev said can be a little tricky bleeding the wetness from the water. It literally blows steam across the room. You have to go easy when steaming small quantities of milk though otherwise you blow it out the jug! Getting microfoam has been a little hit and miss for me and this is due to 2 things: 1 the stupid 4 hole steam tip that shoots steam sideways and out of the jug when at the surface fof the mile amd; 2 me getting use to the stupid steam tip. Even though Im now down to 1 hole as I blocked the other 3 off, its still awkward to use because of the angle of the holes! Ill either get another tip or block the 4 off completely (sikver solder???) and drill a new one in the middle. Its emabrassing for a machine of that calibre and quality. What were VBM thinking????
    6  Problems: None to date. Work like a dream.
    7  improvements or mods: hmm, a bigger water tank might be nice and Ive been thinking about using an external on in addition to its internal one. It just a pain removing the cover to fill the tank, especially if you keep stuff on it. Having said that the tank is **more than adequate*** if you use the machine for espresso only. You will drain a lot of the tank when you go to fill the boiler after steaming.
    8  what other machines have you used (ie what are you comparing it against) : A PIDed Gaggia Coffee Deluxe with adjustable OPV and Silvia Steam wand. VBM is truely in a league of its ow compared to it, and dare I say the Silvia  :

    Overall, all I can say is...where has VBM been all my life!
    Cheers

    Graham,

    Overall I agree with Trevors comments. This is an excellent machine and makes both great espresso and fine microfoam milk. I find it as easy to use (or easier) than my previous machine.

    I can add a bit from my recent experience as I have moved to this machine from a La San Marco domestic machine. Current grinder is a teflon-taped Rocky.



    *snip*
    is it the pitcher angle or size, milk quantity,nozzle, too much steam, too wet, slow to start

    what size milk jug are you using, how full
    what temp do you heat too


    The instructions on the distributors page suggest draining the wand while the machine is heating for steam. This takes a while--about a minute or so and expels a lot of water--about 60ml.

    If I just let it heat to 2 bar and then drain the wand less water comes out before the steam gets dry. This also heats a bit faster.

    I have replaced the 4 hole steam tip with a 2 hole tip that works better on the very small amounts of milk I steam. I have also semi-plugged the holes with a bit of stainless wire. Without this mod the steam was too much, with the milk getting hot in only 3-4 seconds and sometimes spraying all over the kitchen. I usually steam only 50-75 ml in a 300 ml jug. I had no problems with 150 ml in the same jug, just the small amount.

    I use the wand vertical and place it in the middle of the jug for a good result in about 5-8 seconds.

    Hi Graham,

    Sorry for the delay in replying...have been out for a while.

    Milk texturing requires a lttle different technique than the Saeco V/V
    or the Expobar Elegance.

    I hold the Motta 750 ml jug at about 15-20 degrees to vertical, and place the tip as near verticle as possible to the surface of the milk, positioned in the middle of the jug.

    Steam just under the surface to 20-30 degrees C, listening for that chchchch sound, then raise the jug so that the whole tip assembly is below the surface of the milk, setting up a rolling action with the milk, (rather than spinning), to the required temperature.

    Swirl the jug around, and tap a couple of times on the bench if any bubbles are present, then pour.

    Use the same technique, regardless of the quantity of milk, but bear in mind that the Levetta is a powerful steamer, so gradually open the steam valve and use less steaming pressure for small amounts of milk.

    Its not a hard process, just a lttle different than one might usually expect to do, and soon becomes second nature.

    If doing double caps or lattes, I usually third to half fill the 750 ml Motta.

    Hope this helps.

    Trevor

    hi trevor
    thankyou for your comments

    Milk texturing is a little harder to perfect, but comes with practice.

    please explain further
    ok small boiler but would hope that it compared well to a single group or compact commercial machine

    is it the pitcher angle or size, milk quantity,nozzle, too much steam, too wet, slow to start

    what size milk jug are you using, how full
    what temp do you heat too

    compared to the expobar how would you compare

    your comment on the steam wetness is interesting, will be interesting to pull covers off and check boiler pressure and water level

    (heres where it comes into comparing apples to oranges)

    i dont expect all these answers, any will be appreciated

    thankyou

    Graham
