Roasting your first batch on the Ultra

Roasting on the L100 Ultra in six simple steps

The L100 Ultra is an advanced machine with a lot of features. But roasting a batch for the first time is very simple. Roast coffee in just six steps!

Steps

1. Close the drop door to begin preheating the roaster
2. Select a profile
3. Load beans into the hopper and charge
4. Mark first crack
5. End roast automatically
6. Open the drop door to cool down the roaster

1. Close the drop door to begin preheating the roaster

drophandle+down When the drop handle is in the downwards position, the door is closed and the roaster will start heating up. You can start roasting right away, or wait for the drum to warm up and the temperature to stabilise for more consistent results.

2. Select a profile

The top bar on the touchscreen dispays the currently selected profile. To choose a profile, tap on the profile name, and then choose a profile from the list.

3. Load beans into the hopper and charge

The default profiles are all designed for 100-g batches. Weigh out 100 g of green coffee, and pour it into the hopper.

Start the roast by pulling the charge handle to 'charge' the beans (load them into the drum). Let go of the handle when all the beans are in the drum. The roast will start automatically.

4. Mark first crack

Towards the end of the roasting time you will hear the popping sounds of first crack. When you hear first crack, mark it manually by tapping on 'First crack' on the touchscreen.

The L100 Ultra features automatic first crack detection, but by default this is not enabled. Learn more about first crack detection here.

5. End roast automatically

After marking first crack, the roaster will count down the development time, and then end the roast and drop the beans into the cooling tray automatically.

Let the beans cool for around 90 seconds before removing them from the cooling tray. You can start roasting the next batch while the previous batch cools.

6. Open the drop door to cool down the roaster

After the first batch ends, the drop door will close automatically. Once the door closes you can go ahead and roast the next batch right away.

When you are finished roasting, lift the drop handle to open the drum and begin cooling down the machine.

You can also lift the drop handle at any time during a roast to abort the roast and drop the beans immediately. If you end the roast this way, the machine will not close the door or heat up again until you close the drop door manually.
