Barista Tips

When brewing multiple cups:

1. Use a towel to clean and dry the filter basket before filling with coffee. This will help insure even coffee extraction.
2. To maintain the proper brewing temperature, it is important to keep the brew group warm, so:
3. Do not rinse the filter holder with tap water – doing so will cool the filter. It's best to wipe leftover grounds from the filter with a towel.
4. When you're busy with other tasks, like grinding coffee or frothing milk, keep the empty filter holder warm by attaching it to the brew head.

Frothing and steaming milk requires a bit of practice, but you'll be surprised how quickly your skills will develop. The Artisan™ Espresso Machine gives you all the tools you need: a stainless steel jug shaped especially for frothing, a frothing arm that adjusts horizontally and vertically for a comfortable working position, a frothing nozzle designed to enhance frothing, and a "Dial that lets you precisely control the volume of frothing steam.

1. Press the "Button to turn the espresso machine on."
2. Wait until the espresso machine has reached operating temperature; this will take approximately 6 minutes. When the frothing boiler temperature gauge needle climbs into the “zone, the espresso machine is ready to froth.
3. Fill the frothing jug 13 full with cold milk.
4. With the frothing arm pointed into an empty cup, open the "Dial for a moment to purge excess water from the line. To open the "Dial, turn it slowly counter-clockwise; to close the "Dial, rotate it clockwise until it stops.

1. With the "Dial closed, adjust the frothing arm so it's in a comfortable working position, and submerse the tip of the frothing nozzle just below the surface of the milk in the frothing jug.

Close-up of hands pouring liquid from a container into a metal bowl (no visible text or symbols)

1. Slowly open the "Dial by turning it counterclockwise. The farther the "Dial is rotated, the greater the volume of steam that will be released. Tilt the jug to one side to create a whirling motion in the milk, keeping the tip of the frothing nozzle about 5 mm below the milk's surface. If large bubbles are being created or if the milk spatters, the nozzle is being held too high.
2. As the froth expands, it will be necessary to lower the jug.
3. When the frothed milk has expanded to about 14 the volume of the jug, lower the frothing nozzle into the jug to finish steaming (heating) the milk. Keep the jug tilted to maintain a whirling motion in the milk. Steam the milk until it's between 60 and 74 degrees Celsius. (At these temperatures, the jug will be very warm to the touch.) Avoid scalding the milk, which occurs at 80 degrees.
4. Before removing the frothing arm from the milk, close the "Dial by turning it clockwise until it stops. This prevents splattering.

Barista Tips

• Clean the frothing arm and nozzle immediately after use. See "Care and Cleaning" beginning on page 10.
• Lower fat milks are generally easier to froth. Skim milk can be tricky because it froths very easily, with a tendency to form large bubbles and dry peaks that mar its texture. Ultimately, the choice of milk is a matter of experimentation and taste. The most important factors in producing a superior froth are experience and good refrigeration: the colder the milk you use, the better.

Preparing Cappuccino

The Italian word "cappuccino" is derived from "Capuchin," an order of monks who wear garments the color of this most popular espresso drink. A standard cappuccino is a combination of steamed milk and espresso that's capped with a layer of frothed milk; it's usually served in a bowl-shaped cup of 180–210 ml capacity.

To prepare cappuccino, froth and steam the milk before brewing the espresso. This allows the froth to jell slightly and fully separate from the milk. Once the milk is prepared, brew one cup (30 ml) of espresso into a cappuccino cup, then pour the frothed and steamed milk into the cup with a gentle shaking motion. For a show-stopping flourish, top your cappuccino with chocolate shavings.

Hot water can also be dispensed from the frothing arm. This provides a convenient way to make Americanos, tea, or hot chocolate. Filling a demitasse with hot water is also a great way to warm it before brewing espresso.

NOTE: Always dispense hot water into an empty container – dispensing into a cup or jug containing other ingredients may cause splattering.

1. Press the "Button to turn the espresso machine on."
2. Wait until the espresso machine has reached operating temperature; this will take about
   6 minutes. When the frothing boiler temperature gauge needle climbs into the “zone, the espresso machine is ready to dispense hot water.
3. With the frothing arm pointed into an empty cup, open the "☐Dial by turning it slowly counter-clockwise. Then press and hold the "☐Button to dispense water.

NOTE: Residual frothing steam may exit the nozzle before water dispenses. It may take several seconds for water to begin flowing from the nozzle.

1. When the desired amount of water has been dispensed, release the "Button and close the "Dial by turning it clockwise until it stops.

Care and Cleaning

Keeping the Artisan™ Espresso Machine clean is vital to brewing the best espresso possible. Stale coffee oils on the filter holder, filter baskets, and shower screen will ruin the flavor of the most expertly prepared coffee, and any milk left on the frothing arm should be removed.

Before Cleaning the Espresso Machine

1. Turn off the espresso machine.
2. Unplug the espresso machine from the wall outlet, or disconnect power.
3. Let the espresso machine, and any attached parts or accessories, cool.

Cleaning the Frothing Arm and Nozzle

The frothing arm and nozzle should always be cleaned after milk is frothed.

1. Remove the frothing sleeve from the frothing nozzle by pulling it downward. The frothing sleeve can be washed in warm, soapy water. Make sure any openings in the sleeve are free of residue.

Close-up of a hand holding a small object with a tool, next to a mounted device (no visible text or symbols)

1. Wipe the frothing arm and nozzle with a clean damp cloth. Do not use an abrasive scouring pad.
2. Plug into a grounded outlet.
3. Turn the espresso machine on, and let the boilers reach operating temperature. Point the frothing arm into an empty cup and open the “sidial momentarily to run steam through the frothing nozzle. This will clean the nozzle tip.

Cleaning the Housing and Accessories

Do not use abrasive cleansers or scouring pads when cleaning the espresso machine, or any espresso machine part or accessory.

• Wipe the espresso machine housing with a clean damp cloth and dry with a soft cloth.
• Wash the filter holder in warm, soapy water and rinse with clean water. Dry with a soft cloth. Do not wash the filter holder in a dishwasher.
• The filter baskets, drip tray, drip plate, water tank, and frothing jug can be washed in the top rack of a dishwasher, or by hand in warm, soapy water. If washing by hand, be sure to rinse with clean water and dry with a soft cloth.
• Use the shower screen brush or a damp cloth to brush or wipe coffee grounds from the brew head gasket and shower screen.

2. Place the shower screen into the brew head with the smooth side facing down, and attach with the shower screen screw. Turn the screw clockwise until snug.

NOTE: When the shower screen is attached, the center screw should be flush with the surface of the screen. If it is not, remove the screen, turn it over, and re-attach.

Priming After Long Periods of Non-Use

For the best tasting espresso, prime the espresso machine with fresh water after a long period of non-use. Priming will also ensure that the boilers are filled and the espresso machine is ready to operate.

1. Remove the tank, empty any stale water, replace, and fill the tank with fresh water to the max fill line.
2. Fill the boilers with the fresh water. For instructions, see "Fill and Rinse the Boilers" on page 6.

Descaling

Calcium deposits ("scale") from water will build up in the espresso machine over time and may impair espresso quality. Scale should be removed every four months; local hard-water conditions may require more frequent descalings. Use a packaged descaling agent or appropriate decalcification tablets to remove scale.

1. Remove the shower screen from the brew head. See "Cleaning the Shower Screen" to the left for instructions.
2. Make certain the water tank is empty. Following the directions on the descaling agent packet, mix the descaling solution and add it to the tank.
3. To catch the cleaning solution, place a large cup under the brew head (do not attach the filter holder), and another under the frothing nozzle.
4. Press the "Button to turn the espresso machine on. It is not necessary for the boilers to heat before proceeding to the next step.
5. Press the "Button and dispense cleaning agent through brew head for 15 seconds; press the Button again to shut off.
6. Open the "Dial by turning it counter-clockwise, then press and hold the Button for 15 seconds to dispense cleaning agent through the frothing arm and nozzle.
7. Press the "①" Button to turn the espresso machine off.
8. Wait 20 minutes, then repeat steps 4–7. Every 20 minutes, keep repeating steps 4–7 until nearly all the solution in the tank has been run through the espresso machine. Do not allow the tank to run completely dry.
9. Remove the water tank and rinse with fresh water, then replace and fill with fresh water to the max fill line. Press the "①" Button to turn the espresso machine on, and flush the espresso machine by quickly dispensing the contents of the tank, alternating between the brew head and frothing arm. Do not allow the water tank to run completely dry.
10. Attach the shower screen to the brew head. See "Cleaning the Shower Screen" on this page for instructions. Be sure to add additional fresh water to the tank for brewing.

Espresso began as an attempt in the 1800s to quickly brew coffee on demand, by the cup. The goal was to serve the freshest, most flavorful coffee possible and avoid the burned, stale taste of coffee kept warm on a stovetop. To speed the brewing process, coffee pioneers struck upon the idea of forcing water through the grounds under pressure. Steam was initially used to supply the pressure, followed by compressed air, lever operated pistons, and finally, the electric water pump.

Through the decades, the elements of espresso brewing were tested and refined to produce the standards we have today: one cup (30 ml) of true espresso comes from exposing 7 grams of finely ground and packed coffee to 90–96°C water under 9 bars of pressure. In a brief 25 seconds, most of the highly flavorful coffee aromas and oils are extracted, while the more bitter compounds and off-tastes are left behind.

When the ground coffee is fresh and the brewing is done well, the pressurized brew water emulsifies the coffee oils into the golden foam called crema, which crowns the espresso with ultimate flavor and aroma.

Overextraction and Underextraction

Brewing great espresso takes an understanding of what actually winds up in the cup when coffee is exposed to water. Roughly 30% of a roasted coffee bean is made of water soluble compounds. 20% of those compounds dissolve fairly easily, while the remaining 10% take a little more work – which is a good thing, because that less-soluble 10% is acidic, bitter, and generally unpleasant. The goal of all coffee making is to extract the easily dissolved oils and compounds while leaving the rest in the grounds.

If ground coffee steeps in water too long, all the soluble compounds will be extracted, which makes for a very bitter brew. This is called overextraction. The opposite of overextraction is underextraction, which occurs when coffee is not exposed to the brew water long enough, leaving the essential flavors and aromas locked in the grounds. Underextraction results in coffee that is weak in taste.

Whether brewed coffee is overextracted, underextracted, or just right depends on several factors, including the ratio of coffee to brew water, the fineness of the grind, the brewing temperature, and the length of time the water is in contact with the coffee. All these factors are either directly or indirectly affected by the barista's technique.

Before Brewing: The Elements of a Great Espresso

Before the espresso machine is even plugged in, you'll need several elements to produce great coffee.

Fresh Coffee Beans

Great coffee can only come from fresh coffee beans, properly roasted. Many baristas recommend buying beans roasted no darker than a medium roast, the color of which appears as an even chocolate brown. This roast preserves the natural sugars and flavor of the bean, which sets the stage for excellent espresso. A medium roast is the darkest a bean can be roasted without oils developing on the surface.

Darkly roasted beans – which appear dark brown or nearly black – look great, but the extra roasting overwhelms the more delicate coffee flavors and caramelizes any sugars. A heavy "roasted" coffee flavor, often bitter and sharp, will predominate with a dark roast.

To preserve the freshness of coffee beans:

Keep beans in an opaque, air-tight container and store them in a cool, dry place. Refrigeration is not recommended, as condensation tends to form on the beans whenever the container is opened. Freezing can help preserve beans stored for an extended period, but it will also impair flavor.

Great Tasting Water

An often overlooked element of great espresso is the brew water. If you don't enjoy the flavor of your tap water, don't use it to brew espresso – use bottled, purified water instead. Since it doesn't take long for fresh water to acquire a "flat" quality and taste, it's also a good idea to change the water in the tank often and refill the boilers after a long period of non-use.

Do not use mineral water or distilled water – they can damage the espresso machine.

The Right Grind – and Grinder

Espresso demands a very fine, very consistent grind. Blade grinders and inexpensive burr grinders usually fall short when it comes to producing the grinds needed for outstanding espresso.

The best espresso requires a quality burr grinder, like the Artisan™ Burr Grinder. A good burr grinder will maximize the flavor and aroma of espresso by producing an extremely consistent grind with very little frictional heating.

Brewing Temperature

Water temperature and temperature consistency have a direct impact on the flavor of espresso. Great espresso comes from brewing at an optimum temperature, ideally between 90^-96^ C. Modern boilers and thermostats excel at producing and maintaining the right temperature, but there is a complicating factor that is a major concern for baristas: maintaining heat in the brew group.

If water is pumped from the boiler at a near perfect 93^ C, but flows into a filter holder that's at room temperature, the water will cool dramatically – and the actual brewing temperature will be far less than what the best espresso requires. If the water temperature drops below 90^ C, the espresso might still exhibit good crema, but it will acquire a distinctly bitter or sour note.

To Insure Proper Brewing Temperature:

• A lways attach the filter holder (with filter basket) to the brew head when the espresso machine is heating. This warms the filter.
• Always wait until the boilers are fully heated before brewing – at least 6 minutes.
• Dose and tamp your coffee quickly, and brew immediately. This prevents the filter holder from cooling significantly.
• Never rinse the filter holder with cool water if you are brewing additional cups. After knocking the old grounds from the filter, wipe leftover grounds from the basket with a clean towel. Make sure the filter basket is dry before adding more coffee.
• Keep the empty filter holder attached to the brew head when you're engaged in other tasks, like grinding or frothing.
• Warm a cup or demitasse by placing it on top of the espresso machine before brewing. Cups can also be heated instantly with steam from the frothing arm.

The Artisan™ Espresso Machine is designed to provide an optimum brewing temperature. Dedicated dual boilers eliminate the temperature fluctuations common with single boiler designs when alternating between brewing and frothing. The chrome-plated brass brew group heats quickly, and is commercial-size for a very good reason: commercial-size groups retain heat better than smaller groups.

The Espresso Machine does it's part to provide the right brewing temperature. The rest is up to the barista!

Grinding

Great espresso demands the freshest coffee, and the freshest coffee is always ground immediately before brewing. The most delicate aromatic compounds in coffee go stale within a few minutes of grinding, so grind only as much as you intend to brew immediately.

Dosing

Dosing is the process of measuring ground coffee into the filter basket. A single cup (30 ml) of espresso requires 7 grams of coffee – two cups, twice that. If filled level with finely ground coffee, the scoop included with the Artisan™ Espresso Machine is a near perfect measure for one cup of espresso.

Accomplished baristas usually don't bother making precise measurements when dosing: they simply fill the basket nearly to the brim and sweep any excess coffee from the filter with their fingers, leaving exactly what they need. After you've had some experience dosing, leveling, and tamping your coffee, you'll be able to consistently dose your coffee by sight, just like the pros.

If you're dosing coffee without the aid of a measuring scoop, it is important not to overfill the filter basket. Coffee needs room to expand when brewing. If the coffee is crushed against the shower screen, it will prevent an even dispersion of water across the filter, leading to uneven extraction and poor espresso. Here's how to tell if you're overfilling the filter basket:

1. Fill the basket, level the coffee, and apply a good tamp (see the section, "Tamping").
2. Attach the filter holder to the brew head, then remove it immediately.
3. If the coffee in the filter holder has an imprint of the shower screen or the shower screen screw, there is too much coffee in the filter basket!

Leveling

Leveling the coffee after it has been dosed into the filter is a critical technique for great espresso. If the coffee isn't evenly distributed in the filter, tamping the coffee will create areas of high and low density. The high pressure brew water will inevitably follow the path of least resistance, flowing heavily through the low density coffee – overextracting the bitter coffee compounds – and flowing lightly through the higher density coffee, underextracting the flavorful essences. This uneven extraction results in thin, weak, bitter espresso.

To Level Coffee In the

Filter Basket:

• Make sure the filter basket is dry before adding coffee; moisture in the basket will create a path of least resistance for the brew water.
• After dosing the filter with coffee, level the coffee by sweeping a finger back and forth over the filter. Do not sweep in one direction only – this will cause the coffee to pile up on one side of the basket and produce uneven extraction. Try to impart a slight bowl shape to the coffee, with the center lower than the sides.
• Make certain there are no gaps between the coffee and the sides of the filter.

Properly Leveled Coffee

Tamping

Tamping compresses the coffee into a level disc that provides uniform resistance to the high-pressure brew water. Properly leveled and tamped coffee will produce an even extraction of coffee compounds – and great espresso. Coffee that is tamped too softly will be deformed by the brew water, resulting in uneven extraction, a fast brewing time, and mediocre espresso. Coffee tamped too firmly will slow the brewing time, making for a bitter, overextracted beverage.

Proper Tamping Technique

1. The tamper handle should be grasped like a doorknob, with the base of the handle firmly against the palm. When tamping, try to keep the tamper, wrist, and elbow in a straight line.
2. With the bottom of the filter holder resting on a solid surface, gently press the tamper into the coffee with the goal of creating a level surface. Remove the tamper from the filter basket with a slight twisting motion – this will help prevent the tamper from pulling up chunks of coffee.

1. After removing the tamper, some grinds may stick to the side of the filter basket. Tap the filter holder gently on the table to jostle the grinds onto the tamped coffee disc. Do not tap too hard, or the tamped coffee will dislodge or fracture.
2. Apply a second, finishing tamp (also called a polishing tamp). Press straight down on the coffee with about 15 kilograms of pressure, then relax the force slightly (to about 9 kilograms) and polish the coffee by turning the tamper completely around twice.
3. Inspect your tamp. The coffee disc should be smooth and level with no gaps between the side of the filter basket and the coffee.

Measuring Tamping Pressure

9 kilograms, 15 kilograms – how do you know how much tamping force you are actually using? Do what the baristas do: use a bathroom scale! Place a scale on a table or countertop, and tamp your coffee on top of it. Pretty soon, you will develop a feel for how much 9 or 15 kilograms of force is.

Volume

The brew group and boilers are heated. The fresh coffee has been ground, dosed into the filter holder, expertly leveled, and precisely tamped. Now comes the moment of truth: brewing!

For the best espresso, never extract more than one cup (30 ml) using the small filter basket or two cups (60 ml) using the large one. Brewing more will overextract the coffee and result in thin, bitter espresso.

As it pours, perfect espresso is a deep reddish brown with a thick texture like honey running off a spoon. It often forms what are called mouse-tails, or thin syrupy streams. As increasingly bitter and acidic compounds are extracted, the espresso pour will begin to lighten; in some cases, the pour will become almost white. Expert baristas will watch the pour carefully and quickly stop brewing if it starts to lighten.

Espresso Ristretto is espresso brewed with less than normal volume. Prepare the espresso machine to brew two cups, but stop brewing when only 45 ml have been extracted. What you've done is restrict the pour to include only the most flavorful and least bitter coffee oils and essences.

Extraction Rate

Decades of experience have shown that the best espresso – whether a single or a double cup – takes about 20–25 seconds to brew.

If your espresso is brewing much faster or slower than 20–25 seconds, and your tamping technique is good, adjust the grind! Grind finer for a slower extraction rate, and coarser for a faster one. Keep the dose and tamp the same.

Coffee is sensitive to the ambient humidity and will absorb moisture readily. This will affect the extraction rate. In a humid environment, the extraction rate will slow down; in dry conditions, the extraction rate will speed up. You may find yourself adjusting the grind according to the season – or the day's weather.

Some grinders do not allow the fine adjustments necessary to correct the extraction rate. The best solution is to invest in the KitchenAid® Artisan™ Burr Grinder. If this isn't possible, experiment with the tamping pressure. Tamp with less force for a faster pour, and more force for a slower one.

The Golden Crema

A mark of fine espresso is crema, the dense golden foam of emulsified coffee oils that captures the essence of coffee flavor. Good crema should be thick and cling to the side of the cup when it's tilted; the best crema should be able to support a sprinkling of sugar for nearly 30 seconds.

Troubleshooting Espresso as it Brews

As it pours, if your espresso...

...has more of a cinnamon color, instead of being deep brown:

• make sure your brew group and boilers are fully heated
• use a less acidic blend of coffee

...is whitish with thin brown streaks:

- review your tamping technique – the tamped coffee has fractured, or a gap has developed between the coffee and the side of the filter basket

...is thin and fast-flowing:

• review your tamping technique – the tamp may not be firm enough to provide an even resistance to the brew water
• use a finer grind
• check coffee freshness

...barely dribbles out the filter holder:

• review your tamping technique – the tamp could be too firm
• use a coarser grind

A Glossary of Espresso Drinks

Americano

180–240 ml of hot water added to a single cup (30 ml) of espresso. This makes a superb cup of coffee.

Café Latte

250 to 300 ml of steamed milk added to a single cup (30 ml) of espresso. Lattes are often flavored with syrup.

Café Mocha

A café latte with chocolate syrup added, and usually topped with whipped cream and chocolate flakes. It can also be prepared without syrup using steamed chocolate milk.

Cappuccino

A standard cappuccino is a combination of steamed milk and espresso that's capped with a layer of frothed milk; it's usually served in a bowl-shaped cup of 180–210 ml capacity. Powdered cocoa or cinnamon may be sprinkled on top as a garnish.

Classic Cappuccino

Classic cappuccino is common in Italy, and is simply espresso topped with frothed milk.

Doppio

A double cup of espresso.

Espresso Breve

Espresso with steamed half & half poured on top.

Espresso Con Panna

Espresso topped with a dollop of whipped cream.

Espresso Lungo

Espresso "pulled long" – that is, brewed with a greater than normal volume. This technique produces caffeine-heavy espresso which is thinner, lighter-colored, and less full-bodied than normal. To make espresso lungo, brew 45 ml using the small filter basket, or 90 ml using the large filter basket. Use a slightly coarser grind to keep the brewing time between 20–25 seconds; extending the brewing time beyond 30 seconds will make the espresso lungo excessively bitter.

Espresso lungo is often used to make stronger-tasting Americanos or lattes.

Espresso Macchiato

Espresso with a dab of steamed milk added to the top.

Espresso Ristretto

An espresso "pulled short" – that is, brewed with less than normal volume to maximize flavor and minimize bitterness. For ristretto, simply brew about 22 ml using the small filter basket or 45 ml using the large basket.
