Coffee landscape

Coffee can taste as different as wine. So many things affect the taste:

• Brewing / extraction
• Roast degree
• The roast profile
• The kind of bean: origin country, washed or natural processed, botanical variety, altitude, the soil …


The first I will recommend you to get hold of is the roast degree. This makes a big difference to the taste. Often people only like one roast degree and really don’t like the others – and feel strongly about it.


You can tell the roast degree from the color of the coffee. On this picture you can see an extreme light roast in the two cups in middle. This light roasted is the least common on the marked but many younger coffee people prefers it.

On the left is a medium roast. But considered medium-dark to the light roast scene here in Northern Europe – and in other parts of the world considered light. There is no common definitions of roast degree.

Example of mapping the taste

Once I did a mapping of 58 coffee capsules for the Nespresso system. If you can get hold of some of the same capsules you can explore too.

It was for a Danish company that sold other brand capsules than Nespresso. But the customers often asked “I like this Nespresso capsule. Which of yours taste like that ?”. This map shows what is nearby and what is very different.

From left to right (x-axis) is the roast degree going from light to dark.
From bottom to top (y-axis) is “other aroma than what comes from the roast degree”. So the lowest has little ‘other aroma’ and high placed capsules has strong ‘other aroma’.

This is simplified to make a 2-dimentional map.
