Anette’s trip reports

Sunday, January 22nd, 2012

One of the things I’d like to do this year with this blog is highlight coffee writing that I think is great, from all around the web.  You could argue that this particular selection is self serving, so here’s the clear disclaimer:  These articles were posted on our company blog.  I generally try not to link to work stuff on here, but sometimes I think it is entirely appropriate.

Recently Anette has started to write up her travels, starting with Ethiopia in November, and continuing last week with Sumatra.  I really enjoy reading these posts, a genuine mixture of her personality, bountiful information and her insight.  (The fact that English isn’t even her first language shames my poor language skills so deeply.)  I also really like that these are written by someone travelling to learn, and looking to share the information collected. I have no idea how she records as much information as she does!

Posting these makes me realise that there aren’t enough posts like this out there, or (more likely) I’m just not looking in the right places.  Feel free to link me up in the comments! (I read Coffee Collective’s posts, Tim Wendelboe’s and Tom Owens mostly)

I think these posts are very much worth reading – yes, yes I am probably extra biased because of who is writing them, but if you put the time in reading them (they’re pretty long) then I’m confident you’ll come to the same conclusion. (That they were worth reading, not that I am biased!)

A quick poll on brew methods

Thursday, January 19th, 2012

I was thinking about this the other day, and was wondering what other people think. I’ve seen each of the opinions out there, but I’m curious about the distribution of opinion amongst those who read this blog.   I’ll post my own thoughts ont this up with the discussion of the results, but if you have an opinion (and I know you do!) and a moment to spare (which you must if you are reading this!) then I’d appreciate a couple of clicks from you.

Do you think individual coffees are suited to certain brew methods?

  • Yes, I think certain coffees suit certain brew methods - (44%, 233 Votes)
  • Sort of, I think certain coffee suit certain methods of filtration - (41%, 217 Votes)
  • No, I think any brewer can brew any coffee equally well - (15%, 77 Votes)

Total Voters: 527

UPDATE:  I’ve closed this poll.  I will be posting a response to the results pretty soon.

Explanation of yesterday’s graph

Sunday, January 15th, 2012

So yesterday I posted up a little graph to see if people could identify it.  It was a tricky one, and I was pleased when Kevin Cuddeback, CEO of Gimme! Coffee, chimed in with the correct answer.  What the graph represents is the rate of increase of temperature in the bean mass (calculated to be per minute) measured every 30 seconds in a roast.  I removed the first part because formatting a graph to look nice when you’ve got to drop to -100 on your x-axis is difficult.  Plus, it would have made things too easy!

Here is the graph again, properly labelled:

I posted this for a couple of reasons:  Primarily I thought it was interesting.  Secondly I wondered if other people were looking at roast data like this.  I’ve only produced a few of these curves, as I have to do it manually at the moment, and they are confusing to read.  Bear in mind – if the graph were to flatten out it would simply mean that the bean mass is increasing in temperature at a steady rate.  The roast curve would be point up, it would just be straighter.

Other roasts have produced extremely different profiles.  I need to get more data and start doing comparisons!

This is also interesting because there are changes in the rate of the bean mass absorbing heat that don’t correlate to changes in gas or airflow.  I don’t know whether evaporative cooling has much impact on rate, or why we don’t see a faster uptake of heat once the coffee is dry.  The curve on this roast between 6 and 8 minutes is particularly interesting to me.

I should note that this was a test, rather than production roast.  It was dropped not far past 1st crack, as you may surmise from the graph.  We have a colour meter but it doesn’t produce accurate Agtron numbers.  It cupped pretty well, but was out-cupped by a slightly different profile that I don’t have this kind of data for.  (Annoyingly)

Anyway – I thought it was interesting, and I hope it might generate some discussion – because we are really bad at openly discussing roasting theory online.

Cutting edge reporting from the Telegraph

Sunday, January 15th, 2012

There was a most unusual article today in the Telegraph that you can view here.  I’m probably going to do myself no favours by picking up on a few problems with the article, but also in the piece there are some really important points that probably require a longer post that this.

The most avant-garde espresso experts now say that crema is rubbish. Apparently, when you really concentrate on the taste, crema is very bitter. Those in the know treat it like scum, and skim it away before drinking.

This ‘espresso-stripping’ started in fashionable Copenhagen at a place called the Coffee Collective, but it’s now spread to London where its leading proponent is James Hoffmann, a spiky-haired coffee geek who looks a bit like Gareth Malone.

Why yes, of course – I am absolutely the leading proponent of this.  It is all I talk about.  I never drink espresso with crema.  Oh wait, nope…. It actually appears that I just made a video over 2 and a half years ago about how removing it was interesting and worth some discussion or experimentation.  Cutting edge reporting there…..1

One other quote set off a little train of thought in my head – about which I am happy to be proved wrong.  I agree with the quote from Tim, but not the inference that follows.

Williams agrees that the world of London coffee is evolving at such a pace it’s hard to keep up. ‘When I arrived in 2006 a good cup of filter coffee couldn’t be found.’ Now, thanks in part to antipodeans like him, London has become a mecca for coffee purists.

I think antipodeans have had a massive positive effect on London.  However, I would argue that the vast majority of places pushing good filter coffee in London are not Antipodean owned business.  Just a thought.

Onto the really important stuff – that merits its own separate post and discussion really.  (I’m going to skip my quibbles about us going too far with Penny University  It turns out Tim never said this….).  This is something that I agree completely with:

Williams also thinks the current obsession with new gadgetry has become a distraction. Japanese syphons can be a gimmick, in his view. ‘It would be ridiculous to walk into a wine bar and order it by the device the cork’s been removed with!’

I agree.  I think selling the brew method is bad idea.  By this, I mean promoting the way we make a cup of coffee as part of the way we sell it.  We should, I believe, be selling the coffee itself first and foremost.  The price should match the experience and no brew method improves a cup of coffee, it doesn’t make it more valuable. You can argue that “experience” has a worth, a value – so the engagement of a syphon means that it can be sold for more.  I believe that this leads to bad cups of coffee, sold at high prices, justified by the spectacle.  As for argument of theatre – how many performances of exactly the same thing would you pay to see before you got bored?  If I price by the spectacle of the brew then it gets less and less valuable the more often I buy it – not great encouragement for repeat purchases and customer loyalty.

I promise to write up something a little more developed on this topic soon, but in the meantime I probably won’t be rushing out to buy a copy of the Telegraph.  As for the aeropress – I think it’s great, and I swear I once saw a box with a picture of Gareth Malone on the side…

Identify this graph

Saturday, January 14th, 2012

A little bit of fun.  All you have to do is identify what this graph is charting out.  The x and y scales are linear.  It has something to do with coffee.  The first person to identify it will get a bag of tasty, tasty coffee sent to them from me.  Terms and conditions apply1

Also – please leave a comment to guess so other people can see. Submissions won’t be accepted via twitter etc.

UPDATE:

Clearly I’ve made this too tough.  Here is the same graph with a little more information on the axes:

Coffee descriptors

Wednesday, January 11th, 2012

Back in September of last year I was thinking a bit about the words we use when we describe coffee.  Out of interest I went to a few US roaster’s websites and copied all their coffee descriptions into a text document and ran it through wordle.

I then went to Starbucks website and did the same thing with all their descriptions.  The results are interesting, I think and you can click to enbiggen:

Speciality:

Starbucks:

Now don’t take these too seriously – this is hardly the most incisive bit of research.  I’d like to ask if the same thing stands out to you as it does to me – but then I have to ruin the question by giving my own answer.

Speciality  ((how uncomfortable I am with this term)) likes to use nouns.  Solid, statement-of-fact nouns:  This coffee tastes like blackberry.

Starbucks surprised me, not only by their consistent use of acidity which confuses me on a couple of different accounts, because they don’t use as many nouns.  Lots more descriptive words, more adjectives and adverbs.  Are they harder to argue or disagree with?  Perhaps a more accessible way to describe coffee to their customers?

Is there something in the way they do this we can learn from.  I’m not suggesting we spruce up our descriptions with meaningless words, and I will admit that I am uncomfortable with labels when flavour descriptors start verbing, but would describing those factual flavour nouns in our labels a little more be beneficial?

The price of coffee at home

Tuesday, January 10th, 2012

There have been two great posts from Coffee and Conservation recently, detailing Julie Craves’ year of consumption.

I buy a lot of really high-quality coffee. The average price per pound (not including shipping) this year was $22. The big outlier was a half-pound of Finca La Valentina Geisha from PT’s Coffee, which retailed at the equivalent of almost $120/lb. Including that coffee, I indulged in 23 bags of coffee that retailed for over $20/lb. If I take out the five most expensive bags of coffee (over $30/lb) my cost per cup declines to $0.83, or $0.75 without shipping. Most average coffee consumers will be able to bring even this price down substantially without compromising sustainability, or taste.

Great coffee is incredibly cheap.  We’ve been saying this for a long time, but it is nice to have it written aloud by someone buying a lot of coffee as a retail consumer.

Most interesting to me was seeing the increase in per cup cost since 2008.  A mixture of increasing retail prices, perhaps coupled with an increasing preference for certain coffees:

The high elevations of my favorite coffees also stood out to me. The average elevation of these coffee was over 1600 meters! Higher elevation slows bean development, resulting in a denser bean and typically more well-developed flavors. Alas, we may be seeing more coffee grown at these high elevations in the decades to come. This doesn’t mean there will be a proliferation of coffees with characteristics like that of high-grown coffees today. Climate change will mean the temperatures required by fine arabica coffee will move upslope, but of course conditions at 1600 meters may soon be the same as 1200-1400 meters today.

Both posts are an interesting and enjoyable read, and it made me want to do more to track my own consumption in these terms:
