How to Make the Perfect Coffee – A Lesson Learned from the WBC

Thursday, July 22nd, 2010

Disclaimer: This post will not tell you how to make the perfect coffee – I was trying to think of a catchy title and “How to make your coffee taste better by making small adjustments to the brew variables from the standard method – a lesson learned from the WBC” was a little long winded. As in most cases perfection is something to aspire to, but in reality will never be achieved. If anyone can think of a better title please leave a comment.

Now I know that the WBC was quite a few weeks ago, but I thought I would write about it today as I think there is an important lesson to be learned that we can all employ when brewing at home. This lesson doesn’t just apply to brewing espresso, but to any coffee maker.

Stray from the standard brewing method

While the standard brewing method is a great starting point when learning to use a new coffee maker, it’s not a strict recipe that must be followed to the letter. To get the best out of your coffee (or to pursue perfection) you should experiment with the way you make it.

World Barista Championship 2010 – The Results

Sunday, June 27th, 2010

world barista championship 2010If you haven’t heard already, the results for the WBC are as follows:

  1. Michael Phillips (USA) 706 points
  2. Rual Rodas (Guatemala) 691 points
  3. Scottie Callaghan (Australia) 672.5 points
  4. Colin Harmon (Ireland) 659.5 points
  5. Soren Stiller Markussen (Denmark) 644.5 points
  6. Stefanos Domatiotis (Greece) 632 points

Should you have missed any of the action, the videos for all the competitors are still available online here.

The whole event was done really well. The only disappointing thing for me was the drawn out announcement of the final results. Like many people I’m sure, after the final performance by Rual, I wanted to know the results as soon as possible. But instead, I had to endure each and every sponsor being invited onto stage, by the MC, to give a speech.

Could you imagine this happening in the FIFA World Cup? After England beat Brazil in the final (I wish), before Steven Gerrard can lift the trophy we have to hear a speech from all the sponsors.

MC: I’d like to welcome onto the pitch our ball sponsor Adidas.
Adidas: Thank you. This World Cup we at Adidas listen hard to what players and coaches alike wanted from a football. We then went incompletely the opposite direction and took inspiration for the Jabulani ball from those 99p plastic balls you find on the garage forecourt.
MC: Thanks Adidas. Now I’d like to welcome Ronald MacDonald…

Big respect must go to Stephen Leighton of Has Bean Coffee. As a sponsor he had the opportunity (and every right) to promote his company. I can’t remember his exact words, but basically when he was handed the mic he said “Just get on with the results”.

Update: Just watch the announcement back to find out what Stephen’s exact words were. What he actually said wasn’t crude like the words I suggested above – sorry. Light-heartedly Stephen said:

All the baristas rocked. Can we have the results please.

WBC – World Barista Championship 2010

Saturday, June 19th, 2010

WBC - World Barista ChampionshipWimbledon isn’t the only competition kicking off in London next week, as the World Barista Championship arrives in the city. Michael Phillips or Colin Harmon might not be household names like Roger Federer, Rafael Nadal or Andy Murray; but the WBC is a hotly anticipated event in the coffee calendar.

Starting on 23 June, at the Olympia Exhibition Centre, 54 nationalities will compete over 3 days to see who is crowned World Barista Champion. Each competitor must produce 4 espressos, 4 cappuccinos and 4 signature drinks during a 15 minute performance; which will be scored by an expert panel of judges.

To learn more about the event visit the WBC website. You can also watch live streaming of the championship here.

Communicating Grind Size

Tuesday, May 4th, 2010

One of the biggest problems when describing a brewing method is getting across what size of ground coffee to use. The trouble is that each grind setting on a coffee grinder will produce a range of sizes rather than one exact size.

How coffee grinders work

The reason we get a range of sizes from a grinder, is that grinders use a crushing action to break the bean into smaller pieces. On a conical burr grinder, there are two discs: a female cylindrical disc and a male dome shaped disc. Each disc has ridges (know as teeth) running across its surface, and it’s these ridges which crush the bean. Obviously crushing isn’t an exact science. Irregular sized pieces break off from the bean each time it’s crushed between the grinder’s teeth.

If you look at the cross section below of a burr grinder: the bean enters at the top and as it progresses down, the gap narrows between the two discs, breaking the bean into smaller and smaller pieces. The ground coffee cannot escape from between the grinding discs until it’s small enough to fit through the gap at the bottom (indicated by the two red arrows).

Ascaso Update

Tuesday, April 27th, 2010

Yes I know that Ascaso upgraded the spec on its espresso machines back in September 2009; so this isn’t exactly new news. But still I though it was something worth talking about. So I decided to compare the equivalent pre-upgrade machine against a brand new Pablo (before the Update this used to be called the Basic).

So what’s changed?

As standard, Ascaso now fits all of its espresso machines with a solenoid valve. But also: the UK distributor for Ascaso, Fairfax Coffee, has chosen to switch from importing machines fitted with the ‘versatile’ system (which can use both ground coffee and ESE pods) to the ground coffee only system.

Now the versatile system uses ‘supercream’ pressurised portafilters. Which Ascaso boost: guarantees a creamy coffee (no matter how badly you prepare it! – okay I added the last bit myself). The coffee only machines, like their commercial counterparts, don’t have this cheat.

Caffeology – the Study of Coffee Drinkers

Friday, February 19th, 2010

The You CodeAs its Friday, I thought I’d post something light-hearted today. On my usual trawl through the internet looking for all things coffee related, I came across this little gem.

In a new book, “The You Code”, authors Judi James (one of the UK’s leading body language and behavioural expert – according to her website) and James Moore have come up with a new study; a weird mix of coffee and astrology. But rather than stars governing the way we behave, it’s the type of coffee we drink.

This new “caffeology” states:

Espresso Drinkers tend to be moody, hard working and hard living. They are into leadership and fast goals. They can be an experienced, exciting and consummate lover, but are not know for reliability or loyalty.

Cappuccino Drinkers tend to be extroverts and optimists. They have a liking for material objects. They enjoy sex but are easily bored by an unimaginative partner.

Latte Drinkers are typical metrosexuals or cuddly-toy collectors. Have an overwhelming compulsion to be liked. They want to come across as hot shot contenders, but are actually quite immature.

Black Coffee Drinkers are minimalists and take a no-frills, direct approach to life. They can be quiet and moody but are prone to brief burst of extroversion.

Instant Coffee Drinkers are cheerful straight forward types, who like a laugh. They have unadventurous careers and leave their socks on during sex.

It would be interesting to know how the research had been done for this book. There’s only so much you can learn from sitting in a coffee bar. How did they find out whether someone wears socks in bed? Did they stalk customers from Starbucks? Maybe all their friends have stopped inviting them round for coffee after too many personal questions: “Thanks for the cappuccino. But tell me do you own a copy of the Karma Sutra?”

Oh course; it’s all a bit of fun (if a little random). As I drink mostly espresso and black coffee that must make me really moody. Although I don’t think you could call me a minimalist, I’m far too untidy for that.

Caffeine! – Coffee’s Ball and Chain

Wednesday, February 17th, 2010

I read an article in the newspaper over the weekend on a study by the University of Palermo, stating that because of its caffeine content, espresso can be bad for the heart. Right next door to this, another article quoted a study declaring that chocolate was good for us as it helps prevent a stroke. So, if I believe what I’ve read then coffee is bad and chocolate is good.

But isn’t this a bit contradictory? Coffee and chocolate both contain caffeine. And if caffeine slows blood flow, while at the same time increasing blood pressure, chocolate shouldn’t really be recommended to prevent strokes.

It seems odd to me, that whenever there’s a study into caffeine (good or bad), it’s always related back to coffee, even if the amount of caffeine involved would mean drinking a ridiculous amount of coffee.

For example, an article on the BBC’s website talks of a study of how mice taking 500mg of caffeine a day reversed the effects of Alzheimer’s.

“The mice were given the equivalent of five 8 oz (227 ml) cups of coffee a day..”

A small rodent drinking five 8oz cups! So to reverse Alzheimer’s, us humans wound need to drink approximately 14,000 cups, or 45 times our own body weight, of coffee every day. I love coffee but I couldn’t drink that much.

Handpresso Intense Portafilter – Part II

Sunday, February 14th, 2010

handpresso domepodIn the previous post, I was testing the new Intense portafilter on the ESE version of Handpresso’s portable espresso machine. Now it’s the turn of the Domepod (ground coffee) version.

As I said previously:

I’m not quite sure of the advantage yet (of the Intense portafilter), as flow rate can already be controlled by altering the grind size of the coffee.

I did come up with a theory however – that using the Intense portafilter may slow the loss of pressure when compared to simply grinding finer. For some reason the Intense portafilter would be better at stopping the pressurised air from escaping and consequently the coffee cake would be under higher pressure for longer. So to put this to the test I made several ristrettos (yes you can make these with the Domepod), some using a coarser grind and the Intense portafilter and some using a finer grind with the standard portafilter. But I couldn’t detect any difference between the two; so that was my theory out the window!

Back to the drawing board; my big assumption was that everyone has an espresso grinder, with access to 24/7. But that’s not the case. Once I realised this (stupid me) I came up with a list of scenarios where the Intense portafilter is beneficial:

  1. If you do have a grinder but it doesn’t grind fine enough for espresso.
  2. Or if you buy pre-ground coffee but and again the grind size isn’t fine enough.
  3. If you’re going out for the day, and want to drink both espressos and ristrettos, but don’t want the hassle of making up and labelling which pods have which grind size in it.

I’m sure there are other scenarios. Please feel free to suggest any.

Handpresso Intense Portafilter

handpresso intense portafilter
We’ve recently started to stock an alternative portafilter to the standard one shipped with Handpresso espresso machines. So I thought it would be a good idea to put the new Intense portafilter through its paces.

Intense Portafilter

Intense portafilter - fewer holes

The Intense portafilter is designed to slow down the flow rate for a more intense (hence the name!) extraction. The difference between this and the standard portafilter is that this one simply has fewer holes – i.e. fewer holes the longer it takes for the water to flow through.
 

I can immediately see the point of this portafilter for the ESE version of the Handpresso. The biggest problem with ESE pods is that they brew too quickly, resulting in an under-extracted brew. So something that slows the process is going to be beneficial. However with the Domepod (ground coffee) version, I’m not quite sure of the advantage yet, as flow rate can already be controlled by altering the grind size of the coffee.
