Nice Mal. You can almost taste them.
Whats in the grinder? It looks like a fairly young roast from the bubbly crema.
All of the above are Talk Coffees wonderful Yirgacheffe Special Prep. with the Brew Temperature set at 94deg C. This was definitely the sweet spot for these particular beans and probably close to the best coffee Ive ever had... [smiley=thumbsup.gif]
Ive had a brief play with the Controller Settings to ensure that it works with the way I operate quite closely, i.e. maximum rate of climb from cold with no overshoot once Setpoint is reached; quick response from shot to shot with no overshoot and rock-steady performance during a shot.
At all times, once the Setpoint is reached, the temperature remains absolutely stable with no oscillation. Can probably do a little more tweaking over time once I have some more specific data to work with...
The Offset needed to be adjusted too given that Canberra is quite a bit cooler than where we are; reduced from the previous of 16deg C to 13deg C. Indicated temperature is spot on actual now.... 8-)
I really love this machine as do, no doubt, owners of other DB machines with PID Controllers. It opens the potential for even more enjoyment from the bean. You dont need to move the Setpoint temperature around much either - Just a degree up or down from one bean to the next can make a huge difference to the quality of coffee in the cup. Love it.... ;D
Gday Steve.... :)
I think the bubbles are just as a result of entrained air during the pour, not from the crema itself. When the cup is left to sit idle for a minute or so, the bubbles have all but gone.... 8-)
Glad you are enjoying your new baby Mal, and thank you for posting some very useful information.
Now.....where do I get a camera like yours :D
You bet Attilio.... [smiley=thumbsup.gif]Originally Posted by 4B7F687E65524E626B6B68680D0 link=1305962450/56#56 date=1307087067
Ill send you a copy of the settings for the controller that Ive settled on for now too mate - Might be helpful...
Ive only got a little Canon camera but it does produce great quality photos. Its a model "Powershot SX110 IS" but I think theres a later model around now which is supposed to be just as capable but with a couple of refined features that mine doesnt have.
Back to the DJE DB, it is really performing wonderfully and a lot of fun to use. The only pity is that too much coffee means I dont get to sleep :P.... Otherwise Id be consuming beautiful sweet espresso all day long... ;D
Its a beauty mate.... 8-)
That looks like a remarkably rich and syrupy pour for a Yirgachefe. [smiley=cool.gif]Originally Posted by 537E7A767B170 link=1305962450/55#55 date=1307087038
The DJE DB certainly isnt just a pretty face but delivers very well on end product. Im sure other CSers might look to one of these as a double boiler option.
Of course, The Kony-e is an important contributor to those results. [smiley=thumbsup.gif]
Its close to the best coffee Ive ever had and thats saying something. The pity of it is, the bags nearly gone.... :(Originally Posted by 2E24312626293D3B480 link=1305962450/58#58 date=1307089150
::) and the Kony does her bit too of course... ;D
Well.... :) 8-)
Ive been having a bit of a play with Brew Temperatures using two of Chriss excellent S.O. roast offerings and the difference that a single degree C. can have on the end result is quite astounding, and as I remember it from my days with the PID Controller modded Mokita I owned several years ago.
The BIG difference of course, is that the DB Extra is able to hold that brew temperature within 0.5deg.C throughout the shot whereas my modded Mokita could manage, at best, 1.5deg.C through a shot. Rather than repeat everything, heres a summary of my experience in the Cupping section.... ;)
This is a lot of fun... ;D 8-)
Hows the steam Mal?
Great Ronin.... :)Originally Posted by 200C0F0A0D3C34630 link=1305962450/61#61 date=1308461419
Though I rarely use it... ::)
Plenty of high power, dry steam; stretches 300ml (for two Piccolos) in about 15sec. If you have the milk ready to go before you start pulling the shot(s), you can have the milk finished and ready to pour before the shot(s) finish.
Really simple to produce excellent quality, silky and shiny microfoam... 8-)
Sounds like a great machine Mal
Many enjoyable Godshots to you mate
Ive had a good few already I reckon.... 8-)
Gotta say.... 8-)
Im loving the flexibility of the lovely PID DB :P
Just having the simple ability of being able to control the Brew Water Temperature, coupled with the excellent temperature stability of the overall design, Im exploring coffee flavours that Ive never picked up on before. By far and away, Ive been enjoying the best Yemeni espresso Ive ever had, over the last week or so. Simply luscious.... :D
Loving my DB.... [smiley=thumbsup.gif]

+ 1 Couldnt agree more Mal being able to tweak the temp with different beans can make a good shot a Godshot* :P It opens up a hole new ball game :)
Worth every cent in my opinion.... 8-)
For those considering a DB what are the effects of running the machine on a standard power output?
Does it reduce steaming power, result in a heat up time for steaming after a shot etc?
P.S. the machine looks awesome. 8-)
Gday ITC... :)
With my Diadema Extra DB, it is fine to operate it with both Boilers running, just the Brew Boiler, a Priority Mode for either the Steam Boiler or the Brew Boiler and when both Boilers are running, there is an additional Economy Mode that reduces power draw after the machine has been sitting idle for a little while.
With both Boilers On and the Pump running, the DB runs at under 10A so is safe to use with a standard 10A Power Point. This is not necessarily the case with all DB machines though, so you would have to verify that before parting with the hard-earned.
If anything, the Steam Power with this machine, compared to my previous DJE HX machine, is probably a bit more powerful. Textures milk for two standard Flat White coffees in about 18Secs. Used to take about 25Secs with the original. Both the Brew Boiler and the Steam Boiler are completely independent of each other so what you do with one, does not affect the other... 8-)
Warm-up time is probably quicker too but in reality, it is of academic interest more than practical interest for me, as I like to leave the machine warming up for about 30-40 minutes from cold, just to ensure that the entire Group w/Handle is nice and hot. With the PID control though, after the machine is hot, its just a matter of walking up and making the coffee - No need for any flushing, cooling or heating. The pour temperature profile is very nearly flat and right on the money from the moment the Brew Lever is moved up.
A very satisfying and easy machine to use. Probably the same could be said by owners of similarly specd machines too... If youre a bit of a geek when it comes to coffee, these machines will definitely satisfy all the criteria... ;)
...25 seconds...Mal, how tedious! ;D ;D ;D ;DOriginally Posted by 6B46424E432F0 link=1305962450/69#69 date=1311859019

Well, there you go. I didnt realise that.... :)Originally Posted by 487D7077435F737A7A79791C0 link=1305962450/71#71 date=1311890926
We dont drink bucket size milk coffee around here though, probably 100-120ml of milk maximum per cup. If Im just making one for myself in a tiny little jug, it only takes about 15secs... Gotta be on the ball then ;)
YOu should get something like my 6910... that way you have (*lots*) more time to relax and lose yourself in the swirling milk.... :o
;) ;DOriginally Posted by 3832273A373C3B26550 link=1305962450/73#73 date=1312529577
Actually, I find the whole process very relaxing. Unless, I have to churn out umpteen lattes for friends or relos but then I really appreciate the speed.... 8-)
Digging this one up as I'm toying with the idea of an upgrade (it must be Wednesday again).
Can't seem to find much info on these machines, do you still have it Mal? Any concerns or are you still as happy now as you were 5 years ago?
Still very happy with the DJE DB.
Any failures in output these days are down to me, not the machine.
Probably why you might be finding it a bit difficult to find information, is that they are now marketed under the BFC manufacturer name. Still the same machine, but dispensing with the Diadema name tag...
Junior Extra TCI | BFC srl
Thanks for the tip (re name change). I haven't figured out how to search on coffeesnobs for BFC and PID (since they are 3 characters) and if i look for Diadema I get all of the HX posts,
But I'm able to see that BFC in general are well regarded and I figure you'd have discovered any bugs with yours by now, so that's enough to get my ar5e into gear and check one out in the flesh. Cheers.
Don't forget, lots of other great machines to be had in this price range...
If you can, check out as many as you are physically able to get to...
Easiest way to search for specific items...
Any owners of this machine know how to turn off the super loud beep when the machine turns on? Turn the machine on too early and the critters wake up (6 month and 2 year old girls), wait for them to get up and I risk missing my fix before work. I don't need to know that I've turned the bloody thing on.
Anyways, it's amazing how all of the craftsmanship and experience that has gone into making a quality product can be rendered kakaka by a simple setting to the electronics.
It's a control board timeout on autofill. Check that it's not restricted in some way (blocked inline filter, dirty solenoid or similar) when it drinks.
