Coffee beans are turning from yellow to brownish
and it started to smell really nice.
Hey guys, it's Aleš from European Coffee Trip and
in this video I will show you how we roast coffee
in our office using a machine called IKAWA.
Okay, as you know we are not coffee roasters,
but we love to experiment with coffee and
I think it's a dream of every coffee lover
to roast coffee at some point.
For us this dream came true in 2018
when we launched the partnership with IKAWA
to film a series of Roaster Stories videos.
So far we publish 5 stories on our YouTube channel
and of course, we ask them to send one sample roaster to our office.
We get IKAWA pro version 3 model.
So we need to mention a disclaimer
IKAWA is an advertising partner of ours at the time of
filming of this video.
Please don't
expect we'll teach you how to roast coffee in this video.
What we want to show you is how
IKAWA looks and how does it work,
how and why we roast coffee in the office
and also the new update of IKAWA's mobile app
that was released in 2020.
Also at the end of this video we've prepared a bonus for you.
You can win a sample of coffee we will be roasting today.
Here it is a professional sampler roaster.
But why is it called sampler roaster?
Unlike big production roasters that roast several kilos
or even several hundreds of kilos at a time.
Sample roasters are built to roast only
small batches of coffee,
usually around 50 grams.
It's super useful for Coffee Roasters to evaluate coffee
and to make the right decision about coffee to buy.
Before IKAWA
roasters would need to rely on the gas sample roasters
like Probatone that is not easy to operate and rather
inconsistent or on receiving roasted coffee samples from importers.
With IKAWA it's super easy. So even we can do it ourselves.
You just insert green coffee, pick the roast profile
from a library and press the button.
The rest is controlled by the machine itself.
If you look at the IKAWA, it looks very simple
There are only a few buttons and moving parts.
You need to plug it to the electricity,
there is a switch to turn it on and off.
Above that switch
you can see a window that covers a Bluetooth sensor
that connects the machine with an app.
There is a button to heat up the roaster and prepare it for coffee roasting
and there is a button to release coffee after roasting.
There is also a glass jar and a dozer.
If you look from the top you see a dozer and a glass lid
that is magnetically attached and you can take it out.
Then you will see a roasting chamber and what you can't see below it
is a ventilator and a heating element that blows hot air
through the bends to the roasting chamber.
It agitates the beans and allows them to roast evenly
Okay, now, you know the basics, let's roast some coffee
We don't roast coffee in the office to decide which coffees to buy
We use it to educate ourselves and our friends.
Often we have a chance to bring green coffee samples from coffee origins
or we can ask our friends who are coffee
producers, importers or roasters and then use their IKAWA roasting profiles to taste coffee back home.
And that's what we are going to do now.
We got a hundred grams of special coffee from Brazilian coffee farm called Daterra.
It's naturally processed coffee of Paraiso variety that was harvested in 2019.
It's flavor descriptors are mango, peach liqueur and blackberry.
Now, I will show you how we roast this coffee with IKAWA.
I will start by turning on the IKAWA.
Then I will open the mobile app and make sure that the roaster is connected
Now, I need to download the roast profile
It can be from an online library or somebody can share it with me directly.
In our case, we will use Daterra's profile for its Masterpiece collection.
I load the roast profile into IKAWA and let it preheat.
In the meantime, I will measure 50 grams of green coffee and insert it into a doser.
When IKAWA is preheated, I turn the dozer so all the beans fall through the hole into the roasting chamber.
When I turn it back, the roaster will start the roasting process.
When coffee is roasting. 
I can monitor the roast curve in the app
and in the new version, I can easily turn into the landscape mode
or I can smell roasting or watch the colour change through the glass lid
So roasting is in progress. Now it's turning from yellow to brownish and it starts to smell really nice.
During roasting, all the chaff is sucked out into the glass jar.
Once the roasting is over IKAWA turns into a cooling mode
So now roasting is over. Coffee actually is now cooling down inside of IKAWA
It will take another 2 minutes and then we are done.
So in less than 15 minutes since we switched IKAWA on,
we have roasted coffee in a room temperature ready for a brew.
Normally, we would wait one or more days before brewing
but for this video we want to do it right now!
Can't get enough
It's still a little bit harsh. It's only
Come on, it's only 15 minutes after we roasted but the aroma is amazing.
It's like the full of passion fruit
it's really sweet, intense ...
I don't know if I taste mango but really full of fruits
so I'm really looking forward to taste it tomorrow or even later
Later, because Juliana from Daterra wrote me that it's best after seven days from roasting.
Okay. I hope that you enjoyed the roasting experience in our office
and before I get to a giveaway, there are two things I wanted to mention.
Number 1 is that we used IKAWA Pro version in this video
but there is also one designed for home users
So if you like the experience, 
you should definitely check it out.
Number 2: If you already have IKAWA Pro and use it at your roastery, don't wait and update the mobile app.
It's a really big improvement.
Okay now it's time for a giveaway -  to win a sample of coffee we roasted today
