In this video, I want to show you the DE1+,
and I am going to make two shots with the two tablet interfaces, so you get a feel for the different ones.
This is called the Barista Plus interface, it's the one you will probably use every day,
because it makes it easy to just get on with your day and make coffee.
You've got hot water, espresso and steam buttons,
and it uses the current presets.
Now, before I make a shot, I want to show you how you can change the settings.
I am going to use this little pointer here, so my fingers don't get in the way.
So here we are with settings.
We're currently doing a 90°C infusion temperature shot,
with pre-infusion rising to 9 bar, holding for 10 seconds, with a decline time of 38 seconds to 2.0 bar.
Now, the reason I had this profile is I personally like shots where the flow rate slows down to compensate for erosion.
But you can do different kinds of shots.
So, for example, you can take this and shorten the decline time, go and do a 5 bar shot.
It ends at 5 bar, maybe you want to peak at 8.4 bar.
You can just play around very quickly.
And what you do now is hit "save", and it will be ready immediately to do this kind of shot.
So let's go back to where we were.
And I had a hold time of 10, and I was doing a 9 bar shot. Ok.
So, at this point, I am going to take my portafilter,
and I am going to use our grinder/doser, and there's another video that explains how this works.
Now, I am aiming for a 16g dose, I've got 15.8 - that's close enough for me.
I give it a little shake to try and even it out,
and then a few taps
to make it settle
This is our tamping cradle, and typically what I do is hold it like that.
Tamp.
And this is our tamper, which got a spring in it, so you tamp always with the same force.
Go ahead and lock it in. We have a second handle here, which makes it easy to pull it in and pull it out.
At this point, I am ready to make my shot.
Go ahead and put a cup here.
And tap "espresso". Now, what's happening is the water is circulating up right behind the coffee puck,
getting the whole system up to temperature.
You can see that right now, the basket temperature is a little bit under,
as it circulates. And as soon as the temperature of whole system is at 90°C, it's going to go "click",
and you're going to hear pre-infusion start.
There's the click of pre-infusion.
So, pre-infusion is happening at a very low pressure,
the water temperature is right there. The next temperature is right around 90°C.
It's just up the mixed temperature, because our DE1+ is aiming for a brew temperature of 90°C,
not a water temperature. So it's automatically varying the mixed temperature
so that the temperature sensor here is trying to attain 90°C.
And we're very close. We're at 89.5°C infusion temperature,
and you can see that the mixed temperature is actually 92°C.
So what it's doing is compensating for the cooling effect of the coffee grounds, the basket, the portafilter.
And it's a brand-new way to think about coffee brewing:
instead of the boiler temperature, we're thinking about the infusion temperature.
At this point, I consider the coffee is no longer blonding,
and so, I just tap anywhere on the screen, and I've got my espresso.
Now I've come back with one of our jugs. I pre-filled it with milk. I've got our temperature on it,
and I am aiming for a 65°C foam.
And I can go ahead and foam immediately, there's no waiting.
If you can read the display, you can see that we're doing a 152°C foam, which is extremely powerful.
What this allows us to do is do really fine microfoam with very little effort.
You can also see the total water volume, which is giving us the dilution of the milk,
to know it's how many ml of water have we put in here.
And there I am.
So that, if you were watching the timer, it was 32 seconds to steam
6 ounces of milk.
Now I am going to go ahead and pour the latte art.
And here is your coffee, ready to be served!
