Siliconslave's how to make espresso thread

so 30g in and 50g out - so slightly below a 2:1 ratio.

Now just done another cup into a glass cup and the ratio of coffee to crema seems to be out. At the moment I am getting about a 80% coffee and 20% crema at the most - whats the best way to increase the crema - tamping pressue / volume of coffee or size of grind?
 
Is that what you're getting at the moment?

Presumably that's a double shot? I wouldnt worry about the ratio of crema, 80:20 sounds about right, and it'll only go up when you get some decent beans in there. All 3 of those will affect it.
 
Yeah, thats what I am getting at the moment, and it is double shot - might have to drop down to single shots going forward, but enjoying the balance in a latte.
 
single shots are usually more tricky than doubles, because they require even finer control over the variables.

Just stick with doubles and tweak for correction. It'll never be exactly the same every time. Variations in humidity, age of bean, temperature of the water, etc. etc. all make for slight fluctuations in every shot pull. The trick is to get it to within a tolerance and just enjoy it. :)
 
So Hasbean order has just arrived:

El Salvador
Jail break
Blake
Kicker
Jabberwocky

Also got a Knockbox to go with the Barista Express as well.

Very much looking forward to indulging in some proper coffee - however as they were roasted yesterday should I give them another couple of days, or are they good to brew today?
 
If you're just using them for espresso they should probably wait a week or so, I'd be tempted to try one of the blends though to dial it (almost) in. :)

EDIT: Try one with the Blake blend (seems to be the cheapest from that bunch, less £ to waste if it isn't perfect) - see what you feel. Weigh in & out.

Good luck!

Spent some time last night properly dialling in and weighing my latest batch of coffee. It made me realise that I'd really let things slip previously. The results are *so* much better now. Like..night and day.
 
Let us know how you get on Bar! :-)

@FrenchTart - yep, doesn't matter how familiar you are with it, it really does start to 'slide'. I tend to just weigh every shot now as it's pulling (bit different on a lever machine) just to keep everything spot on and save on beans :)
 
Finally managed to take some pictures - shocking quality, but they give the right views.

Having played with ths Barista Express for a couple of weeks now I can honestly say it is an incredible machine. The control you have over the grind and the quality of the build is exceptional. It looks and feels professional and yet is quite forgiving. It comes with 4 filter sizes: Single and Double both in standard and pressurised forms. You can control both the grind size and the grind amount which has come in very useful. It is only single boiler so you do need to wait a little if you are heating milk or wanting hot water however this is no more than 30 seconds.

Finally got onto the Jabberwocky blend and I wanted to take you through the process with the Barista Express:

First of all grinding the beans, this has been dialled in for the new beans and I used the automatic setting, however as you can see you can manually control it.

Once ground its time to tamp, and here the Barista Express again provides so much support to the novice, a nicely shaped and weighted tamp goes along with the Razor which helps you ensure you are at the right level within the filter:

You can see on the top of the tamp a small metal disc - this slots into a holder within the Barista and attaches magnetically.

Once tamped its time to pour. A simple push of the button and the Barista Express goes through a low pressure pre infusion phase and then a more high pressure pouring phase:

Pressure was a little high, so will increase the grind size a little for the next pour, but it didnt overly affect the final product:

Delicious. Will do a proper review of the various blends, but the Jabberwocky is certainly one of the nicer 4 that I have tried.

And for those that like that kind of thing - the puck comes out perfectly everytime and never seems to be too wet or too dry:

I am considering Breville/Sage Barista Express machine, the utube Seattle coffee review suggests steam comes from a thermoblock so water is directly heated electrically and could do this at same time as making coffee (if you have turned it on in anticipation);
also that brewing is done by a thermocoil, a similar mechanism.
Seattle coffee have a video showing a cutaway thermocoil : search what is a thermoblock for those interested ..... I want to see inside before I buy.
it was unclear if the machine would need back-flushing ?

The reviews I have seen all point to it having a single boiler and my experience would also seem to indicate you have to brew and then heat up for steam.

Once you have steamed however it has a valve to vent excess steam / heat back out of the boiler and into the drip tray to get it back to the optimum brewing temperature.

For its price bracket I havent seen anything else that comes close all things considered.
