There’s a cafe in Georgetown, Penang, designed by SK Leng, a man with a mild obsession for coffee. Under the espresso counter he’s got pipes running into empty upside down filter housings (to act as a small reservoir) and BWT bestmax PREMIUM ion-exchange filters stripping out calcium and adding magnesium to his water with testing points and connections for planned adaptations in several locations. His irrigation system is constantly changing; I’ve never visited this cafe without seeing some change to the way that he waters his coffee. To most people, water is H2O and that’s it. To health conscious GMO avoidant modern consumers, removing calcium and adding magnesium seems like the work of Dr. Frankenstein. Why would anyone want to do all this to pure, natural water?

The design of the coffee bench is very important for workflow. It must flow for the baristas to get the coffees out fast. The design constraints are the size of the chiller and the direction of flow. If the chiller can be located elsewhere, it frees up the design, but the barista will still need a small fridge to keep a few ready cartons of milk to hand. An icebox is another option. I’ve found that, although it takes up a lot of space, working with a fridge for milk and a freezer for ice is preferable.
Below is a link to a 3D rendering of the bench above. Continue reading
All the baristas working at my cafes sit an exam (here’s a link to it). Most fail the first time round and that’s nothing to be ashamed of. The modern barista has to mentally wrestle with concepts that include knowledge of physics, chemistry and fluid dynamics, they need to have the palette and confidence of a good chef and be charming when relating complex concepts to the customers. We all forget how much we’ve learned and getting people to learn all these things is difficult. I have a genuine passion for coffee and I want people working with me who are genuinely interested in coffee and can enthusiastically impart that passion to our customers. Training is very important to me. Continue reading
Factory visit 1/11/2011
A visit to the Dutch equivalent of Santa Claus for good baristas in his hometown of Eindhoven.
First, I have a confession: I initially saw the Kees’ machines as equipment that was style over substance. Being suspicious of tight jeans and periwinkles, I have always preferred practical clothing and practical equipment. I’m more of a Linea or a Cyncra kind of a guy, machines that only need a set of tank tracks and a turret to be useful to the Blues and Royals. I had seen the Mistral and thought it looked a thing of beauty, but, I assumed, in a botoxed-bimbo-I-look-like-fun-until-I-open-my-mouth kind of way. It looked too pretty to be able to make serious coffee; I suspected it to be vulnerable to break-down and sudden faints. Continue reading
The death of ristretto, volume and single and double shots.
I still get a lot of people asking for a ristretto and I’m always interested in what they mean. Usually, they’re after something with less bitterness than a typical short black. If the coffee is of the fourth or fifth stage, restricting the pour makes sense: if a double shot means 60mL, then by cutting the pour at 40mL we’ve got a cup of liquid that is less bitter than had we carried on to 60mL. Restricting the pour with six stage coffee makes no sense.
In sixth stage coffee, the barista has set up the pour so that there is a balance of acidic, sweet and bitter tastes. Cutting the pour early produces a very sour cup.
Had a quick visit to Starbucks. My first visit to Starbucks in six years. Things have changed. There’s wood everywhere, great little nooks with interesting local designs and plaques to describe the features. The place is well thought out and is much more welcoming than any chainstore I’ve been to before. It’s the new concept store in Amsterdam and I think Starbucks has hit the mark with it’s new concept.

Coffee comes from the area that is now Ethiopia. Interestingly so do we. Fossil and genetic research suggests that all modern humans originated in the same area as coffee. It is impossible to know if your great x 10^4 grandfather was munching on coffee products. However, for the next 9928 generations there was probably more munching than drinking. Archaeological evidence suggests it was common around 800AD to press the cherries into ball of fat to preserve them for long journeys[i]. At some point some bright spark started boiling water and using the leaves of the coffee plant to make a stimulating infusion. Since then the way that coffee is drunk has changed dramatically six times over the past 600 years. Continue reading
19/9/14 Nota Bene. This post was relevant to particular style of coffee (light to medium), roasted on a drum roaster (Diedrich IR5). Our current roaster (Loring Merlin) roasting a similar style of coffee leads some coffees – especially natural-processed coffees – to swell the bags up and occasionally burst. We currently cut open and vacpack these coffee bags again a couple of days after roasting. This is only the case for 1kg bags. 250g bags are not affected. We shall be ordering 1kg bags with valves in the future.
Yesterday I decided to do away with one-way valves on our roasted coffee bags when packing with a vacuum. It’s been something that I’ve been testing for many years now and time again I’ve come to the conclusion that they really don’t make that much difference to the coffee. Indeed, too often they provide an access point for oxygen to enter the bag and degrade the coffee.
One-way valves are supposed to let CO2 gas out of the bag while preventing O2 getting into the bag. Oxygen is the main culprit behind the staling of coffee and packaging is an attempt to extend the vitality of the beans. Continue reading
At Artisan, we’ve all spent hundreds of hours practicing how to make a cup of coffee. It’s not just that we’re obtuse. To understand why it takes us so long to get a decent brew, you need to understand four things about coffee: concentration, extraction, brew ratio and temperature. Looking at these aspects of a drink might seem overly fastidious (verging on wanky) but, for those of us with simple passions, they are highly necessary. Continue reading
