Siliconslave's how to make espresso thread

Matched shower screen and filter basket is definitely worth it - i do remember back in the depths of this thread when someone was ribbed for buying a nanocoated basket but IMS or VST do seem to make a real difference to the pour :) \

How have you found going to 14g Raymond - i'm tempted so i can get away with an extra coffee in the day but not convinced its going to give enough flavour.
 
Rave does seem a bit commercial now. Try Dorset coffee company over Rave. Their Australian skyberry is very nice. £23 a kilo of beans.

I think Rave have just been very good at their marketing etc - I do wholeheartedly recommend trying different roasters though, there are so many excellent options around and more popping up all the time.
In fact my brother is just starting to roast semi commercially - should be getting some beans through from him any day now...
 
Have you got a set of scales? I find now I am getting MUCH MUCH better coffee with the Niche, partly because it is a better grinder but partly because every shot now I am putting in accurate weight of coffee. Actually so much so I might upgrade my scales, only using some £15 ones but I find that it isn't that accurate, it lags and sometimes putting a single bean can make it move the numbers, sometimes it doesn't.

Arr the scale problem - seems finding a fast, accurate and waterproof scale is a real challenge - very tempted by a perl but for now i'm just using a cheap jewelry scale and trying to be careful with it. Although this is the second version as the first had half an espresso poured over it which apparently the screen doesn't like!
 
VST basket - maybe you need to change the gasket - it maybe baked in on the old baskets gauge, afaik they do not publish guages.

A silicon gasket is a good investment from the sounds of it - they don't bake themselves into the machine so you don't end up having to chisel it out later down the line - wish i'd know about them with my classic but will be replacing with one on the maraX...

Theres someone building a 'smart' scales on coffee forums - https://coffeeforums.co.uk/topic/53374-coffee-scales-diy that looks pretty cool - I do need to start my temperature and timing Raspberry Pi build at some point
 
For weight they are great, nice and accurate to 0.1g and consistently sensitive - I've added 0.1g to 500g and it detects it just fine - but the smart timer is a gimmick.

Isn't the timer more relevant for pour over where your time accuracy isn't anywhere near as granular?

Project wise i'm looking to put a magnetic switch on the pump which gives an accurate time of how long thats running and theres a serial connector on the marax that pumps out the current temperature. If i could add a scale into the equation then i'd be all set for a totally over the top doc brown contraption...

Oh yes, absolutely. I suspect this is the case for all smart scales.

The problem is with espresso the time to start pouring can vary and its relationship to the quality and output is a little vague (and related to pre-infusion and pressure profiling) so timeing from the weight change isn't really helpful unless its linked to the pump - decent have started playing around with this on their machines and scale, as do some of the high end commercial setups. For hobbyists its only useful for pour over where you're trying to control in the time it takes to pour & filter.
 
Generally measuring volume out is considered as being inconsistent as the crema can throw things off. If your measuring the volume of liquid pumped through by the machine its a lot more consistent.

You have to remember with home espresso there are so many variables going on and were trying to narrow them down by stabilizing (or trying to at least) a few of them. We're also only pulling a few shots a day so ideally want a way of looking at what's worked in the last shot (or not) and trying to find the right formula to repeat or fix it 12 hours later. Pouring a few starter shots to get things dialed in every morning isn't really viable either :(
 
Yep, just done that and all good. Just had to peel the paper filter off before I did the plunge.

aren't you just binning the filter as well? Its compostable as well...

Used up the last of my beans last night. Waiting for delivery today.

i've managed to do the opposite for once and have about 3kg of coffee for once, i'm usually running out about a week before my subs come in!
 
i'm sure James Hoffman does a little swirl after inverting the grounds cup into the PF (from memory). I do quite want a dosing cup, motta do one I may have to order...
I have been reusing them, just rinse it off and leave it in the cap to dry after rinsing out the rest. Been reading about the metal filters which I may try just for testing sake really.

a little out of date but this is quite interesting: https://perfectdailygrind.com/2015/01/aeropress-filter-comparison-the-big-test/
 
Also the E61 design means that some water will always be retained until you remove the PF (where it promptly drops onto the PF/puck anyway). There is always some water backed up to the valve inside the head itself.

Exactly, the 3 way valve in the gaggia is great for a dry puck, e61 less so - its annoying when turning out the puck as it can make a real mess.

As were posting our pucks heres this mornings (needs a bit more dialing in):
