Copper, the perfect boiler material

by Reiss Gunson on Friday, 05 August 2022 12:59

Sometimes i read of people expressing a view that stainless is a vastly preferrable material for an espresso machine boiler, or even more oddly a group

Copper is hihgly malleable, ductile, and most importantly has unmatcheed electrical and thermal conductivity (unlike stainless which performs very poorly in this regard)

Additonally it does not suffer from metal fatigue from the repeated heating and cooling cycle that a boiler is subject to

Critically copper will not rust as stainless will if you end up with less than 12% chromium anywhere in the stainless as a result of fabrication, for example stamping the stainless where you create the mounting face for the heating element on the boiler (warranty claims arising from just this is i understand how the original Faema firm went out of business)

Stainless is thought by some to be more hygenic than copper, but that is not the case either

I saw this article on copper and thought you might find it interesting, so here it is; https://theconversation.com/amp/copper-is-great-at-killing-superbugs-so-why-dont-hospitals-use-it-73103

Copper is wonderful, but it has become expensive and for that reason we will not be using it on the boiler of the forthcoming Vectis model

& for the record copper does not have any lead in it, it is not an alloy, it is a pure metal that you can find on the periodic table at number 29

At last, a small 58mm spring lever group.  Direct fill, no pump, dipper fed, steam wand.  20cm wide, 30cm deep

LONDINIUM no grease piston & group seals are coming

by Reiss Gunson on Friday, 08 July 2022 21:50

Whilst waiting for the Vectis group to be forged i have busied myself developing piston seals for the modern lever group that do not need any grease whatsoever

It has taken a few iterations, but i have now ironed out the material and the design and i am waiting for the first run of 30 sets

If they are well received we will then get dies made and make them in volume

I expect the set of 30 to arrive in a couple of weeks from now; they are being manufactured here in Auckland where i reside so it is a simple matter of driving across town when they are ready and we will have them the same day

These seals will last much longer than 12 months, you will not get any grease trapped in the shower screen causing channelling, you will never need to regrease the seals, and coffee residue will not adhere in the grease in the mesh of the shower screen in the way that it currently does

So the benefits are vastly longer seal life, avoid the need to use expensive silicone grease, vastly increase service life for the shower screen (especially the fine 35 micron screen) and fewer hours servicing the machine and more time drinking coffee

These seals will only be available as an post purchase upgrade to the machines

These seals will transform your user experience whatever brand of lever machine you have if it uses the modern lever group; KVDW, Bosco, Quickmill, Profitec, etc, etc - this is the small insignificant upgrade that will transform your lever life

To fit the piston seals soak them in water and a drop of dishwashing detergent and also wet the piston in the same solution before you fit each piston seal; this will ensure the seals do not grab and tear as you work them onto the piston

Pleased to announce that we have sold our first LONDINIUM II to Croatia

by Reiss Gunson on Thursday, 02 June 2022 08:48

73 countries in all

Today, Thursday 2 June and Friday 3 June are public holidays in the UK but I am still available online to take your questions

Next week should be interesting when we receive the Vectis group back from the electroplaters, chromed, and from there we can assemble the group and see how it looks

The only two deliverables we are working on for 2022 is the Vectis and a new website that works properly on mobile devices as that is how most of your are accessing our website these days, a far cry from 2012 when we first laid the current website down

We might add a 58.55mm tamper for VST baskets and a couple of other tweaks, but that's it

There are no other changes planned

kind regards

An experiment: Ten years of drinking almost entirely single origin espresso

by Reiss Gunson on Saturday, 30 October 2021 12:13

Please note that what i have written below only relates to espresso

Having pursued single origin espresso for the last ten years in something of a search for excellence i have reached a conclusion, perhaps heretical to some, but never mind.  It is absolutely the case that there are some fabulous off the charts single origin/single estate/microlot espresso roasts in existence.  They are an absolute joy to experience, in many cases delivering flavours in the cup that you might not have thought coffee could deliver.  Almost always i order 1 kilo of any coffee so i get to taste it change from when it is just a few days post roast to when it is several weeks post roast, and tasting this progression is very helpful if you want to understand the roast and detect which flavour notes drop out as the coffee ages and which notes appear from the background that were not noticable when the coffee was at its freshest

However as much fun as it is discovering these single origin gems, and i will still be buying single origins that strike me as interesting, i have found that i have tired of their one dimensional aspect which is almost always present.  after ten years of single origin i am tired of a single off the wall flavour note that i never expected to taste in a coffee.  now i want those flavour notes but i want the full orchestra, i want balance.  i wanted perhaps two or three of these off the wall flavours carefully chosen by an expert coffee roaster to compliment each other in the way that heston blumenthal does with food.  what do i want?  i want a blend.  not a traditional coffee blend which is shorthand in the industry for penny pinching and trying to flog low grade coffee at a premium, the proverbial silk purse from a sow's ear, but a blend of single estate and microlot speciality coffees

The leads into my next thought.  in a good number of cities in the world there are now a good number of great coffee roasters; competition between them is high.  i think they need a new trick, a new product offering, and here is what i think that new product offering could be.  perhaps some are already doing it, i dont know

Speciality coffee has become obsessed with precision, at least by some practitioners.  Take grinders for example where users are weighing to a tenth of a gram and performing particle distribution analysis of the grind to determine the distribution of the size and shape of the grounds that the grinder is producing, and measuring grinder tolerances in microns.  But here's the thing; what about when you buy a bag of coffee that is a blend?  The beans separate by weight and the beans separate by size, just as any bag of an aggregate material will, but no attempt is made to address this.  It can be guaranteed that with a bag of blended coffee the proportion of each coffee that makes up the blend is going to vary with each 18g of beans that you scoop out of that bag, and its going to vary a lot.  Perhaps this doesnt trouble you at all, in which case click away and read no further, but i think this is letting the game down, particularly if you have purchased a blend of speciality coffees which if it is true to label you will have paid a lot of money for; you deserve a consistant taste experience with each shot you pull and to achieve that you need to lock in the proportion of each of the constituent beans in each dose you measure

The only way to lock in the proportion of each speciality coffee in the blend as the roaster wanted you to experience is if the roaster sold you the constituent speciality coffees in the blend before they mixed them

So, if their speciality blend contained say five different speciality coffees they would then sell the five coffee in the ratios that you need to make the blend.  So the blend might consist of 1 part coffee A, 2 parts coffee B, 5 parts coffee C, 3 parts coffee D, and 1 part coffee E.  The roaster could sell these coffees in 200g bags, so in the above example you would be buying 12 lots of 200g, a total of 2.4Kg, which some individuals might find too much but i think there are work arounds such as measuring out the coffee beans into individual bean cellers that many home barista enthusiasts already have and use and then freexing those that you think you wont be using for some time.  Then you have 2.4Kg of coffee that you have pre-blended at the exact ratios that your favourite master roaster envisaged you experiencing.  When you want a coffee you take the lid off the bean cellar and pour it into your single dosing grinder

Possibly roasters will baulk at that and just say we sell in 250g minimum and if the ratios of the blend dont divide cleanly into 250g portions, then tough, and i think the market would accept that as the beans left over could always be consumed as single origin or combined into new experimental blends, either way i dont see that it would go to waste

For sure this is a niche market and it wont be of interest to many, but i think in an increasingly competitive market for coffee roasters this is a point of difference they could offee that would not involved them buying any more coffee and not having to blend it would be one less step too.  The only downside might be having to offer the coffees that are only present in the blend in small proportions in smaller bags they perhaps they currently offer

On the customer side i would definitely be prepared for the extra work in blending the coffee myself in return for locking in the ratios of the blend so they were the same for every shot i pulled of the blend

If you are wondering if a blend you are considering purchasing is a speciality blend a good way to tell if whether the exact beans used in the blend have been disclosed on the bag.  If they have not you can safely assume it is not a genuine speciality coffee blend.  You would also expect that the beans in the blend are also available for sale by the roaster as single origin roasts, another good cross check

Personally i think carefully considered blends of speciality coffee are the future of specilaity espresso cofee because they give you the full orchestra taste experience, rather than one spectacular flavour note performing alone

little londinium

by Reiss Gunson on Sunday, 06 June 2021 16:14

UPDATE: 10 JUL 21

the little londinium is not going to follow a drip fed release to market approach, unlike most of our previous models

the 4 pre-production units will be assembled and tested, revised if necessary, and then signed off into production

the production components will then be produced and the machines will be assembled and the product will then be made available for purchase on our web store

one thing is cerain the news will break here first, rather than any social media platform

 

UPDATE: 3 JUL 21

the UK foundry have not delivered us the 4 sample lever groups for sign off into production, something we expected in May

we now have all the other components in house and there is nothing more for us to do other than wait

i am told by those experienced in dealing with foundries that it is a bit of a feature of the industry, but its frustrating none the less

there isnt much else to say as we have now taken all the project steps that are within our control as far as we can (boiler, portafilter, heating element, valves, seals, frame, power leads, packaging, etc, etc)

our suspicion is we may not receive the lever group until august 15

the only good news is when it does finally arrive we should be able to move quickly to assemble it

-------------------------

 

 

we remain on target to get a pre-production sample together this month, june

that isnt a guarantee that it will happen, but nothing has occurred yet which will prevent it from happening either

some people are taking some well earned holidays this week and on their return we will start putting pieces together

elements, seals, boiler, sheet metal fabrications are all very much in hand; the lynch pin in this project is the all new compact 58mm spring lever group which is a gem

rapid prototyping takes you so far, but it isnt until you screw all the real pieces together that you can see for sure how it performs

we're also looking to ship it with polystyrene free packaging as we feel we can do better in this area

kind regards

Prepay EU tax and duty option now available on machine orders

by Reiss Gunson on Tuesday, 25 May 2021 18:05

We have finally got around to adding the ability to prepay duty and tax for any machine order that is shipping to a country that is a member of the European Union (EU)

Apologies for taking so long to get around to it; we have a few long over due jobs like this hanging around

The next big one is a redesign of the website so it runs properly on mobile devices

Keep checking in, we have plenty of news to come in 2021
