TYPES OF EXTRACTION

With the pressure gauge, you can read the brewing pressure during espresso extraction.

Below you will find an explanation of the terms under-extraction, optimal extraction, and over-extraction:

UNDER-EXTRACTION

With under-extraction, you get a very thin, flat, and underdeveloped coffee. The coffee flows into the cup very quickly. Too few components have been extracted here. The coffee is very light, or the crema is very thin, absent, or the crema is very pale with large bubbles.

• Brewing pressure less than 7 to 8 bar.
  • Coffee flows into the cup very quickly.
  • The coffee tastes sour or flat.

Possible reasons for under-extraction

Cause	Solution
Grind size too coarse (falls out of the grinder very quickly, the ground coffee feels quite coarse when rubbed between the fingers).	Grind finer, gradually adjust to the optimal grind size.
Too little ground coffee.	Use more ground coffee, observe the maximum fill volume, and if necessary, also adjust the grind size.
Channeling: Tamping is uneven.	The tamper should rest evenly and not at an angle on the compressed ground coffee. Otherwise, channels can form in the coffee and the hot water will flow through the coffee too quickly.
Beans are not fresh or ground coffee is not fresh (possibly pre-ground for too long).	Ideally, store the beans in the resealed coffee packaging. Light and oxygen will otherwise cause the coffee to age. Only take as much coffee as you will use in the near future.
Beans are too lightly roasted.	Lighter beans behave somewhat differently during brewing than darker ones and are usually brewed at lower pressure. By adjusting the quantity and grind size, you can also prepare a delicious espresso with different flavour notes. However, this can only be briefly addressed within the scope of this manual.
Brewing temperature too low	Adjust the brewing temperature in the menu

OPTIMAL EXTRACTION

With optimal extraction, the espresso flows evenly, slowly, and with a honey-like consistency from the spout into the cup. The crema is dense and dark to golden brown.

• Brewing pressure from 7-8 up to 12-13 bar.
• Tamping pressure approx. 15 kg.
• Ground coffee evenly distributed in the group handle.
• Optimal grind size, not too fine, not too coarse.
- Beans are fresh or ground coffee is freshly ground.
• Optimal water temperature, not too cold, not too hot.

OVER-EXTRACTION

With over-extraction, too many bitter compounds are extracted from the coffee. The preparation takes a very long time, and the coffee drips slowly into the cup. The coffee is very dark, and the crema is dark brown to reddish and tastes very unpleasant and bitter, or even burnt. The pattern on the crema is uneven, with light spots among darker areas.

• Brewing pressure above 13 bar.
• Coffee flows slowly (extraction time well over 30 seconds) and drips into the cup.
• The coffee tastes bitter and burnt.

Possible reasons for over-extraction.

Cause Solution
Grind size too fine (falls out of the grinder rather slowly, the ground coffee sometimes feels like powder when rubbed between the fingers).	Grind coarser, gradually adjust to the optimal grind size.
Too much ground coffee. Use less ground coffee, and if necessary, also adjust the grind size.
Beans are too darkly roasted.	This is rare with purchased beans. If roasting beans yourself, end the roasting process earlier.
Ground coffee is left in the brewing unit for too long before preparation.	The ground coffee can change its aroma due to the temperature. As a result, the coffee tastes burnt even with otherwise optimal extraction. After locking in the group handle, brewing should be started immediately.

Brewing temperature too high. Adjust the brewing temperature in the menu.

MANUAL ESPRESSO PREPARATION (FACTORY SETTING)

IMPORTANT!

See the Preparation chapter for warming up the group handle, the system, and the cups. Insert the filter insert for one or two cups. Then start espresso preparation.

• Carefully dry the group handle.
• Grind the desired amount of coffee directly into the group handle.
• Tamp the ground coffee with the tamper. Make sure to press evenly and straight so that the water can later flow evenly over the entire surface.
• Insert the group handle firmly into the machine.
• Place one or two cups under the spout.
• Push the toggle switch upwards 📁 to start espresso preparation. The current flow time appears on the display. Ideally, the flow time should be around 20–30 seconds.
• As soon as the desired amount is reached, push the toggle switch downwards again O.
  • The brewing time will be displayed for 10 seconds.
• Remove the group handle and knock the coffee grounds into the coffee grounds container.
• Clean the filter insert of coffee residue and lock the group handle back in place.
• Push the toggle switch for espresso preparation upwards 📁 and briefly let water run through to remove any coffee residue sticking to the filter.
• To end the process, push the toggle switch for espresso preparation downwards O.
• Clean the filter insert and the group handle and place them on the drip tray to dry.

IMPORTANT!

Optimal espresso preparation depends on many influencing factors. The unit is delivered with factory settings for brewing time, brew volume, brewing temperature, etc. For optimal espresso and milk froth, you can adjust the parameters in the programmes for perfect coffee enjoyment.

ADVANTAGES OF CONTROLLED ESPRESSO PREPARATION

Controlled espresso preparation via brewing time or brew volume gives you the ability to programme a reproducible extraction – for consistently enjoyable coffee.

ESPRESSO PREPARATION USING THE SET BREWING TIME

To prepare espresso with a fixed brewing time, you must first adjust the factory settings. To do this, open menu item 1 TIMED BREW. There you can save the desired brewing time, display the currently saved brewing time, and activate the brewing time mode. A detailed description of the brewing time menu can be found later in this manual under "Programmes & settings". After successfully activating and saving the brewing time, proceed as follows:

• Carefully dry the group handle.
• Grind the desired amount of coffee directly into the group handle.
• Tamp the ground coffee with the tamper. Make sure to press evenly and straight so that the water can later flow evenly over the entire surface.
• Insert the group handle firmly into the machine.
• Place one or two cups under the spout.
• Push the toggle switch upwards 📁 to start espresso preparation. The current flow time in seconds appears on the display "TOO".
• As soon as the set time is reached, the process stops automatically.
• Push the toggle switch downwards again O.
• Remove the group handle and knock the coffee grounds into the coffee grounds container.

ESPRESSO PREPARATION BY VOLUME

To prepare espresso with a fixed brew volume, you must first adjust the factory settings. To do this, open menu item 2 VOLUME BREW. There you can save the desired volume, display the currently saved brew volume, and activate the brew volume mode. A detailed description of the brew volume menu can be found later in this manual under "Programmes & settings". After successfully activating and saving the brew volume, proceed as follows:

• Carefully dry the group handle.
• Grind the desired amount of coffee directly into the group handle.
• Tamp the ground coffee with the tamper. Make sure to press evenly and straight so that the water can later flow evenly over the entire surface.
• Insert the group handle firmly into the machine.
• Place one or two cups under the spout.
• Push the toggle switch upwards 📁 to start espresso preparation. The current flow time in ml appears on the display "V00".
• As soon as the set amount is reached, the process stops automatically.
• Push the toggle switch downwards again O.
• Remove the group handle and knock the coffee grounds into the coffee grounds container.

HOT WATER DISPENSING

• Switch on the unit. "PREHEAT" appears on the display.
• As soon as "G" is displayed, the unit is ready for operation.
• Place a cup under the steam wand.
• Set the toggle switch to .
  • Hot water flows into the cup.
  • End the process by pushing the toggle switch downwards O.

MILK FROTHING

• Switch on the unit. "PREHEAT" appears on the display.
• As soon as "G" is displayed, the unit is ready for operation.
• Press the control knob to switch to steam mode.
• The unit now heats up to steam temperature. "STEAM HEAT" appears on the display.
• Fill the supplied milk jug about halfway with cold milk (straight from the refrigerator).
• When "*G*" is displayed, the unit is ready for frothing.
• First, point the steam wand at the drip tray and push the toggle switch for steam upwards 🌐 to release condensate. Push the toggle switch downwards again ○ once the condensate has been released and steam is produced.
• Turn the steam wand outwards and immerse the steam nozzle just below the surface of the milk in the jug.
• Switch on the steam 🌐. The correct position is reached when a steady slurping sound can be heard. You are now in the stretching phase, during which air is incorporated into the milk. Slowly lower the jug as the milk level rises.
• Once the desired volume is reached, raise the jug so that the steam nozzle is fully submerged in the milk.
• This is the roll-out phase. Hold the jug steady and place one hand flat against the exterior surface. The milk should now swirl without drawing in any more air. If air is still being drawn in, slightly adjust the position of the steam nozzle.
• The milk froth has reached the correct temperature when the side of the jug becomes too hot to touch comfortably.
  • End the process by pushing the toggle switch downwards O.

IMPORTANT!

Only remove the steam wand from the milk after the toggle switch has been pushed downwards.

- Carefully remove the steam wand from the milk.

• Tap the milk jug lightly on the tabletop to remove any remaining large air bubbles. By gently swirling, the froth is distributed evenly and achieves a fine, creamy texture.
• Clean the steam wand immediately after frothing to prevent milk residue from sticking.
• Briefly release steam from the nozzle and then wipe the wand from the outside with a damp cloth. Be careful of the heat.
• If you do not wish to froth any more milk, press the control knob 🎨/ 🌐 to switch back to coffee mode.
• The unit will now display "COOLING" and the system will be cooled by flushing with water.
• When "G" is displayed, the unit is ready for coffee dispensing.

IMPORTANT!

During several consecutive cooling processes, steam may come out of the drip tray. This is completely normal.

IMPORTANT!

To practise, you can use the following method:

• Pour cold water into the milk jug.
- Add a drop of dishwashing liquid.
• Froth this mixture as described above.
- If you perform the frothing process correctly, the mixture will look like real milk froth.

Please do not drink this mixture!!

DESCALING REMINDER

The factory setting for the descaling reminder is 25 litres. After 25 litres have been used, "DESCALE PLEASE" will appear on the display once every 60 seconds. Additionally, the control knob illumination lights up red. You can continue to use the unit as usual, but the reminder will continue to appear on the display. The descaling reminder will only disappear and the illumination will return to white after a complete descaling of the system (see the "Descaling" chapter). The volume in litres can be adjusted according to your usage and the hardness level of your water.

12 l = (Hard water over 15°dH)

25 l = (Medium water 7.3°dH to 14°dH)

50 l = (Soft water up to 7.3°dH)

You can find out your exact water hardness from your local waterworks. How to change the volume in litres can be found under SETTINGS = "8 DESCALE REMINDER".

DESCALING

Perform descaling regularly, at the latest when the descaling reminder appears and the control knob lights up red. We recommend using Graef descaling tablets. You can purchase these in our online shop at www.graef.de under item no. 145618 or from your specialist retailer.

IMPORTANT!

We accept no liability for missing or insufficient descaling. In this case, the warranty will be void.
