Steam Powered espresso makers

Steam Powered espresso makers Were The First Machines Invented To Extract Espresso With Steam Pressure And Boiling Water. These Machines Extracted Espresso By Utilizing The Steam Pressure At 1.5 Bar In The Boiler To Force The Water Through The Coffee Grinds. The Total Extraction Time Was About 1 Minute. These Machines In The Early 1900's Produced A Sour, Burnt Taste Created By The Steam That Was Mixed In With The Boiling Water. The Interesting Point Is That Most NON-Pump Machines Sold Today For Under $150.00 Utilize This Old World Technology.

Manual Lever espresso makers
(Spring Or Non-Spring Lever Operated)

Circa World War II, The Piston Was Introduced Whereby The Water Was Filtered Through The Coffee Grinds With The Aid Of A Manually Operated Piston And Without The Addition Of Steam In The Water. In Other Words, The Boiling Water And Steam Were Removed From The Extraction Process. The Sour, Burnt-Tasting Espresso Was Re-Invented Into A Flavorful Cup With The Removal Of Steam Pressure.

These Manual espresso makers Are Categorized By The Inclusion Of A Manually Operated Lever And The Lack Of An Electric Pump. Pre-Empted By Steam Powered Stovetop Espresso Makers, Manual espresso makers Were The First Devices To Produce Espresso As We Know It Today!

There Are Two (2) Types Of Manual Lever espresso makers: Non-Spring Operated And Spring Operated. With The Non-Spring Operated Type espresso maker, The Operator/Barista Lifts The Lever From The Down Position To The Up Position To Allow Water Into The Brewhead And Then Firmly, With Consistent Pressure, Forces The Lever In A Downward Motion To Make Espresso. The Non-Spring Operated Manual Machines Are Recommended For Seasoned Espresso Enthusiasts And Those That Can Meet The Challenges In Finding The Appropriate Amount Of Manual, Consistent Pressure To Extract An Espresso. In 1961, The Commercial Application Of This Espresso Extraction Was Domesticated Into A Home Unit Called "Europiccola" Manufactured By La Pavoni S.P.A. Today, Both The La Pavoni Europiccola And Professional Lever Models Are Representative Of This Type Of Non-Spring Operated Manual espresso maker.

The Spring-Operated Lever Type Manual espresso makers Work The Opposite... The Operator/Barista, Starting With The Lever In The Up Position, Presses The Lever Downwards Against The Resistance Of The Spring In The Piston To Allow Water Into The Grouphead. Once Enough Espresso Coffee Has Lined The Bottom Of The Cup, The Operator/Barista Allows The Spring To Push Up The Lever With Consistency. Today, The Spring-Operated Lever Type espresso makers Are Represented In Most Commercial Lever-Type espresso makers And The Elektra Home Model espresso makers.

Overall, Manual Lever espresso makers Are Best Suited For People (Coffee Bar Baristas, Espresso Enthusiasts, And Home Machine Hobbyists) That Truly Enjoy Pursuing The Mastering Of Techniques To Extract Espresso With Maximum Control Over All Aspects Of Espresso Extraction (Except The Temperature). The Reason Is That Ease Of Use Is Considered Very Challenging, But Attainable Through A Longer Learning Curve Compared With The Shorter Ones With The Electric Pump Machines Listed Below.

The Challenges Include Finding The Perfect Grind To Extract Your Espresso With Crema And Pressing Or Releasing The Lever With Consistency. An Excellent Burr Grinder Is Essential For These Manual Machines As A Coarse Or Inconsistent Grind From An Inexpensive Grinder Will Result In A Poor Shot Of Espresso. The Spring-Operated Manual Machines Are Slightly Easier That The Non-Spring Since The Spring Will Provide Greater Consistency Of Upward Push In The Lever.

The Reward For Utilizing A Manual espresso maker Is The Resultant Flavor Extraction That Is Second To None. In Other Words, Owners Of These Manual Lever Machines Are Usually Disappointed With The Flavor Profiles Produced By Other Machines.

Most Home Model Lever Machines Have A Boiler That Also Doubles As The Reservoir. Since There Is No Separate Reservoir, The Manual Lever Machines Do Need To Be Powered Down And The Steam Pressure Relieved Before Refilling The Boiler. Therefore, Lever Machines Are Not Suitable For Entertaining At Family Gatherings, Functions, Or Events. The La Pavoni Europiccola Can Produce 2-4 Cappuccino Beverages Before Having To Refill The Boiler. The La Pavoni Professional Can Produce About 5-6 Cappuccino Beverages, While The Elektra Lever espresso makers Can Produce Up To 10 Cappuccinos. There Are No Limitations On Commercial Lever espresso makers Due To The Fact That A Required Direct Water Line Will Refill The Machine Boiler.

Manual Home Model Lever Machines Are Also Not Suitable In Environments With Children Or Others That Can Be Injured From The Hot Brass Boilers That Are Exposed To Human Touch. Care Must Also Be Taken When Utilizing The Spring Operated Lever Machines As To Not Let The Lever Be Accidentally Released To Allow The Lever To Spring Upward And Cause Injury In The Facial Area Or Eye Sockets.

Due To The Design Of A Single Boiler On Home Model Lever espresso makers, Steam Pressure Is Readily Available For Frothing Milk. This Is An Advantage To The Electric Pump Home espresso maker Types Listed Below That Have A Wait Time To Get Up To Steaming Temperature.

Cleaning And Maintenance Usually Include Cleaning And Descaling Once A Month, And The Plated Finishes Cleaned With A Soft, Cotton And Damp Cloth. Cleaning Agents Are Not Recommended As To Not Remove The Clear Coat Finish Placed Above The Plated Finish. Finishes Typically Include Chrome, Brass, And Copper.

The Semi-Automatic espresso makers

Shortly After The Advent Of The Manual Lever espresso maker, An Electric Pump Machine Was Invented By Gaggia. The Electric Pump Machines Gained Popularity Quite Rapidly Over The Piston Type Of espresso makers Due To The Comparative Ease Of Use. Specifically, The Electric Pump Removed The Inconsistent Pressure That Was Being Applied On The Lever By The Baristas Of That Era.

A Switch Was Used To Engage The Pump And To Disengage The Pump Once The Extraction Was Completed. This Machine Type Whereby The Operator Controls The Amount Of Water That Flows Through The Coffee Grind Was Called Semi-Automatic. Although This New Technology Became Quite Popular, The Serious Espresso Enthusiasts Remained Loyal To The Piston Type Machines And The Resultant Tastes That Were Being Produced.

Another Advantage Of The Semi-Automatic espresso maker Was The Ability To Allow More Or Less Water To Flow Through The Coffee Grinds. With The Piston Style Machines, This Was More Difficult As Only Som Much Water Coffee Be Engorged Inside The Piston At Any One Time. The Ability To Pump More Or Less Water Into The Coffee Grind Allowed For A Greater Variety Of Espresso-Based Beverages We Consume Today - Namely Cafe Crema, Espresso Ristretto, Espresso Lungo, Etc...

With The Advent Of An Electric Pump, The Possibility Of Refilling The Boiler Became A Possibility. Direct Water Lines And Reservoirs Were Quickly Introduced Whereby The Operator Had A Separate Control To Refill The Boiler With Additional Water And Without Powering Doen The Machine. This Unlimited Water Supply Allowed For An Increased Capacity During Periods Of Higher Demand.

On Commercial Semi-Automatic Machines, The Design Allowed Immediate Steam Availability. This Was Accomplished By Maintaining A Single Boiler (With Hot Water And Steam) And A Heat Exchanger (Coiled Tubing In The Boiler Originating At The Pump And Ending At The Grouphead). As Cold Water Was Being Pumped Through The Heat Exchanger,It Would Be Heated By Transfer From The Hot Water And Steam Already In The Boiler. The First Commercial Semi-Automatic espresso makers Had Boilers That Required The Operator To Manually Refill Them With Water. If They Were Not Refilled, Damage Would Occur To The Heating Elements In The Boiler. Most Of Today's Commercial Semi-Automatics Have Automated The Task Of Refilling The Boiler With The Inclusion Of A Motherboard Inside The Casing Of The Machine And Water Level Sensor Placed Inside The Boiler.

However, On Home Model Semi-Automatic espresso makers, The Smaller Size For The Kitchen Counter Would Not Allow For The Larger Boiler That Can Contain One Of More Heat Exchangers. Therefore, Home Model Semi-Automatic espresso makers Were Designed In The 1970's With A Single Boiler That Operated At Two Temperatures Ranges - One For Espresso Extraction And One For Steaming. These Temperature Ranges Were And Are Controlled By Thermostats. The Thermostats Were Engaged By A Switch That The Operator Controlled. Opposite From The Psiton Style Machines Whereby Steam Was Readily Available, Home Model Semi-Automatic espresso makers Have A Wait Period When Alternating From Espresso Extraction Mode To Steaming Mode And When Reverting From Steaming Mode To Espresso Extraction Mode. However, The Wait Times Can Be Lessened When Alternating Between Modes With Certain Techniques. There Also Have Been Advances In Technology To Reduce Wait Times - These Technologies Include Advances In Boiler Design (Smaller Boilers Known As Thermoblocks) And The Inclusion Of Secondary Heating Elements Pleaced Inside The Boiler. The Only Advance Made On Commercial Machines, But Not Home Machines, Is The Automatic Water Refill. The Majority Of Home Model Machines Have Boilers That Need To Be Refilled Manually By The Operator Usually Through The Engagement Of The Coffee Switch.

Overall, Semi-Automatic espresso makers Are Best Suited For People That Wish To Produce A Quality Cup Of Espresso, While Maintaining Much Control Over The End Result With Greater Consistency Than A Manual Lever Machine. Cleaning And Maintenance Include Cleaning And Descaling On A Monthly Basis. Mild Detergents Can Be Used On Plastic Bodied Machines, And A Damp, Cotton Cloth With Detergents Is Recommended For Metal Bodied Machines.

The Full Automatic espresso makers

All The Commentary For The Semi-Automatic espresso makers (Commercial And Home) Are The Same For The Full Automatic Machine - Except For Volumetric Dosing Which Was Introduced In The Late 1970's. In Other Words, The Full Automatic Machine Will Measure The Amount Of Water That Passes Through The Coffee Grind. Once The Preset Amount Is Reached, The Machine Will Automaticlly Shut Off The Water That Passes Through The Coffee Grind.

The Pre-Set Amount Of Water To Be Forced Through The Coffee Grind Is Usually Programmable By The Operator On Commercial Machines. However, The Solis Home Model espresso maker Line Does Not Allow Programming. In Addition, Most Full Automatic espresso makers Allow The Operator Utilize The espresso maker As A Semi-Automatic Whereby The Operator Can Control The Amount Of Water To Be Pumped.

In A Newly-Established Commercial Environment, The Recommendation Is To Equip The Business With A Full Automatic To Maintain Greater Consistencies In The Espresso Products Served. Full Automatic Home espresso makers Are Recommended Where A Greater Consistency And Greater Ease Of Use Is Desired Amongst A Group Of Users. Same Cleaning Schedule And Regimen From The Semi-Automatic Machines Apply.

The Superautomatic espresso makers

Up To This Point, ALL Of The Above Machines Required The Operator (Whether A Coffee Bar Barista, Espresso Enthusiast, Or Home Hobbyist) To Control The Factors To Master An Espresso Extraction. However, In The Last 10-15 Years, A New Class Of Machines Has Been Introduced Whereby Many Factors Are Controlled By The Machine. These Machines Are Known As A Superautomatic.

These Automated Machines With Single Or Dual Electric Pumps, Grind Whole Coffee Beans Using A Built-In Grinder With Hardened Steel Conical Burrs, Measure The Appropriate Amount Of Coffee Grinds, Tamp (Compact) The Coffee Grinds Into A Puck In The Extraction Chamber, Measure The Appropriate Amount Of Water Through The Espresso Coffee Grinds, Dispense The Espresso Or Coffee Beverage, And Eject The Extracted Coffee Grind Into A Dump Container Removable For Easy Cleaning. Most Superautomatics Have Some Type Of Indicator (Whether Leds Or Digital Displays) To Warn The Operator Of Low Water, Out Of Coffee Beans, Or A Full Dump Box. This Automation And Features Are Found In The Most Basic And Least Expensive Superautomatic espresso makers.

Enhanced Features Found Mostly On Higher End Superautomatics Include Self-Cleaning Systems For Maintenance And Automatic Frothing Devices. Self-Cleaning Systems Range From Removable Brew Groups To Internal Rinsing Cycles To Automated Descaling Cycles. The Higher End Machines Also Allow For The Use Of Automatic Milk Frothers Whereby Milk Is Drawn From A Milk Container And Automatically Creates Froth Into Your Cup.

Although Superautomatic espresso makers Provide The Greatest Ease Of Use With "Push-A-Button" Technology, Many Espresso Enthusiasts Shy Away From These Machines Due To The Loss Of Control Of The Fundamentals To Extract An Espresso. Although This Is True For The The Most Basic Superautomatic espresso makers, The Mid-Range And Higher End Superautomatic espresso makers Allow For Greater Flexibility With The Following Varying Features:

Grinder Adjustment: An Adjustment Can Be Made To The Grind Fineness. All Other Parameters Being Equal, A Finer Grind Will Usually Result In A Stronger Extraction. A Coarser Grind Will Result In A Weaker Cup.

Dosage Of Ground Coffee: An Adjustment Can Be Made With Respect To The Amount Of Ground Espresso Coffee Is Dosed Into The Extraction Chamber. All Other Parameters Being Equal, The Greater The Amount Of Ground Coffee, The Stronger The Espresso Will Be. Less Ground Coffee Will Result In A Weaker Beverage.

Tamping Pressure: Currently, There Are No Superautomatics That Allow Varying Degrees Of Tamping Pressure.

Dosage Of Water: Superautomatics Perform Like Full Automatic Machines - They Dose The Water. However, On Superautomatics, The Volume Of Water Is Operator Programmable By A Dial Or Push Button.

Bypass Doser: This Feature Allows The Use Of Pre-Ground Coffee To Be Placed Into The Brewing Chamber Without The Whole Bean Coffee To Be Ground And Dosed Into The Same Chamber. Typically, There Is A Limitation Of One To Two Scoops Of Pre-Ground Coffee Than Can Be Utilized Through The Bypass Doser For Each Extraction. This Feature Is Great When Decaffeinated Coffee Is Desired Over Regular Espresso (Especially In The Evening).

Pump Pulsation: When The Steam Mode Is Engaged On A Superautomatic, The Heating Elements Are Engaged To Bring The Boiler To A Higher Temperature. The Pump Also Begins To Pulsate Water Into The Boiler So That The Boiler Does Not Run Out Of Water While The Present Water Is Converted To Steam. In Essence, The Steaming Capacity Is Almost Limitless.

Insta-Steam/Rapid Steam: This Feature Allows The Operator To Reach Steaming Temperature Within 15-20 Seconds Of Pressing The Steam Button. When The Steaming Option Is Disengaged, There Is No Wait Time To Retract Back To Espresso Extraction Mode Due To The Fact That Insta-Steam/Rapid Steam Superautomatic Models Have A Separate Boiler Devoted For Steaming.

In Large Volume Espresso Bars And Commercial Establishments, Superautomatic Machines Can Automatically Froth And Steam Milk Into The Same Cup Without The Operator Moving The Cup. Some Also Make Different Beverages At The Touch Of A Button. Although These Superautomatics For High Volume Espresso Serving Establishments Are Priced Over $12,000 Each, They Are Ideal Where High Turnover Of Employees Is Great (Equates To Lower Consistency And Increased Training Costs) And Required Production Of Beverages Is Very High.

As You Can See, The Superautomatic espresso makers Do Allow Some Control Over The Espresso Extraction Process. The Results Are Desirable For Consistency And Very High Ease Of Use. These Superautomatic Machines Are Highly Desirable When A "Significant Other", Such As A Wife, Girlfriend, Boyfriend, Fiancee. Etc, Places A Very High Priority In Cleanliness - Since These Machines Contain Most Of The Grind Within The Unit.

As Far As The Espresso Extraction, Lots Of Crema Is Produced Utilizing "Vienna Roasted" Or Espresso Roasted Coffee Beans. Very Oily Beans (Usually French Roast) Can Be Undesirable Since It Can Gum The Burr Grinder Just As It Would A Standalone Espresso Grinder. Also, Superautomatic espresso makers Typcially Produce Lots Of Light Colored Crema, So For Those Few Who Prefer Dark Speckled Crema, Another Type Of espresso maker Would Be More Preferable.

One Of The Positive Outcomes Of The Superautomatic espresso makers Is The Ease Of Producing Cafe Crema Coffee. Very Popular In France, This Coffee Is Produced Under The Extraction Process Utilized For Espresso Except That A Much Greater Amount Of Water Is Passed Through The Coffee Grinds. The Resultant Beverage Is A Cup Of Coffee With A Nice Layer Of Cream On Top. This Is Certainly Different Than Drip Coffee Where The Water Is Extracted By Allowing Water To Be Soaked In The Coarse Coffee Grind With The Force Of Gravity Pulling The Coffee Beverage Through A Filter.
