A podcast for coffee roasters. This is NOT an introduction to start roasting coffee, but for people who already roast coffee. It's about all the different ways of doing it. The coffee roasting process is very complex. The taste is affected by so many things. It's difficult to control completely. Different roasters use different ways to control the process: the time, the color, the smell, the bean temperature - and the possibilities are increasing with new technology.Made by Therese Brøndsted from Denmark.

Do you go for more acidity or more body in your roast ? How do you roast a Kenya for a light espresso ? And how do you present your beloved coffee for the ignorant customers ?

Tony Jacobsen own a coffee shop and roastery in Trondheim, Norway, Jacobsen og Svart. As in episode 2 and 3 I interview him about how he decides to stop the roast. And then he got some crazy weather changes that affect the roast.

Rank #3: #5 Listening to the beans cracking

Podcast cover
Read more

Back in history before you had a temperature probe in the roaster you could listen to the crack and look at the color of the beans. This episode is about listening: counting seconds from the start of crack.

It is a mix of my own background in coffee roasting and roaster Mikkel Selmer from La Cabra.

I had already planned this episode when we had Danish Roasting Championship last month. Here I had opportunity to make short interviews with the participants in the competition. Mikkel Selmer was one of them and his way of roasting just fitted in to this episode.

And then I have a soundbite with James Hoffmann from his YouTube channel – with his permission.

Rank #4: #8 Roast degree

Podcast cover

The very light roasts are worlds apart from the darker ones roasted to Second Crack. Light roast is a very small part of the marked and strange to most coffee drinkers. But many coffee people loves it.

An american coffee roaster was surprised to hear in this podcast that a roast could be stopped before the First Crack is over.  In this episode I talk with him about the differences. His names is James Simon. We did kind of a cultural exchange: he tried a light roast on his roaster … and I tried roasting to Second crack.

James Simon has been roasting coffee for 12 years in the family business Almost Heaven Desserts and Coffee in West Virginia, USA.

Theo Maitre from Sigfreds Kaffefabrik

Rank #6: #7 Sample roasting at bean importer

Podcast cover
Read more

Kaya Caretta is roaster at the bean importer Nordic Approach in Norway. This is only sample roasting: each batch is 100 grams and the roaster is a small Probat gas-roaster. It’s very different from roasting 120 kilos as Kaya did in her former roaster job.

Daily she roasts more than 40-60 new coffees … apart from their coffees in stock.

I was curious on how she roasts the many different coffees – and what differences she sees in the many origins.

We talk color change, smell, blue smoke, weather change and the mysteries of how coffee beans are different. And of cause I ask: how do you decide when to stop the roast ?

Rank #7: #9 Geisha part 1

Podcast cover
Read more

When you buy specialty coffee you quickly notice that the most expensive green beans are Geisha coffees. This botanical variety got famous from the farm The Hacienda la Esmaralda in Panama. Since Geisha have been planted at many farms in different countries – and still priced higher than other good coffees. That made me wonder: How good are they ? How different are they ? Are they worth the price or are they hyped ?

This is part 1 in a series about Geisha.

Roast degree makes a big difference for the taste of coffee. But other factors can make the coffee taste roasty and smokey.

This time I visit Ida Kofoed Lindhart at Kontra Coffee in Copenhagen. Recently they changed roasting machine: From a 65-years old Probat to a brand-new 70 kg Loring.

#13 When the taste change

Podcast cover
Read more

When you roast the same bean on a regular basis and do the same roast profile – most of the time the taste turn out approximately the same. But sometimes it doesn’t anymore. That could be the beans getting older or changes in the environment.

This time I visit Cristian Scigliano, barista and roaster at Andersen & Maillard in Copenhagen.

I also hear from roasting consultant Michael de Renouard and roaster Kenneth Kastberg. We first heard from Kenneth in episode 6. This time he tells about how he build in pressure measurement in an old roaster.

I have written a post about the factors in changing weather.
