Fundamentals for Reaching "Espresso
Nirvana"
For traditional, semi-automatic espresso machines
Note: The following does not fully apply to
superautomatic, hand lever, or steam power-generated espresso machines
that may operate under different principles and guidelines for proper
operation .
Part III: The "Arte"
This is where we put it all together! Although your pump driven
espresso machine will apply the required water pressure and proper
temperature, you will need to focus on the interdependent variables
to reach "Espresso Nirvana"! In other words, you
will need to adjust the different variables that you can control
in the order we have outlined below:
Preheating
First and foremost, it is extremely important to preheat the portafilter
handle, filter basket, and cups you will be extracting into. Otherwise,
the crema will not be achieved due to the fact that the loss of
heat will not allow a proper extraction. the espresso beverage will
have a cooler, weak, and/or bitter flavor profile. We recommend
filling your cup with hot water from the steam wand on your espresso
machine and pulling an"empty shot" of about 4 ounces of
hot water through a filter handle and basket (without coffee).
Cup warmers on the top of most espresso machines are only effective
if the cups have been heated for at least 1-2 hours. This is not
preferred for home model espresso machines since damage to the machine
can occur without operating it for this period of time.
Fresh Roast of The Coffee Bean
The selection of the type of coffee is yours. Remember, it is advisable
to stay within the four (4) roasts previously mentioned. For lighter
roasts and consumption of straight espresso, we recommend our Italian
imported coffees from Segafredo.
For darker roasts and for beverages with milk, we suggest our own
1st-Cup espresso coffees - Mid-Morning
Blend or Decaf Espresso. Utilizing one of these coffees will
rule out the chances of using a coffee bean inadequate for espresso
extraction. However, do not hesitate to experiment with the various
coffees - estate, varietals, or blends - from the many different
coffee suppliers and roasters found on the internet today. Then
again, you may want to Roast
Your Own Beans!
Fineness of The Coffee Grind
Our universal measurement for fineness of the grind is NutraSweet.
Each type of coffee and roast can be fine-tuned from there - slightly
coarser or slightly finer. In addition, it is important to grind
only a minimal amount above what you need. Ground coffee loses its
aromatics and taste profile with 7 Minutes of grinding. As your
espresso beans age, the oils in the beans will begin to evaporate
or dry. These beans will need to be ground finer since there is
less oil to achieve that golden cream. This is similar to lighter
roasted coffee beans that have less oils right from the start. They
need to be ground finer.
Make sure the fineness of the grind is consistent throughout. If
it isn't, the water being pumped into the filter basket will flow
through the coarser grinds due to the fact that the coarser grind
is a path of least resistance. The result would be overextraction
of the coarse coffee grinds and possible underextraction of the
finer coffee grinds.
Dosage
The Typical Measurement For The Fundamental Rule Is 7 grams of Ground
Coffee (Or One Level Non-Compacted Scoop That Is Usually Provided
With the Machine) Per Shot (1.0 -1.5 ounces) of Espresso To Be Extracted.
For Beginners, We Always Recommend Using The Double Dose Filter.
It Is Typically Easier To Achieve The Fundamental Rule. When Utilizing
The Double Filter Basket, Place Two "Level" Scoops of
Freshly Ground Coffee Into The Basket. If You Decide To Utilize
The Single Filter Basket, Place Only One "Level" Scoop
of Freshly Ground Coffee.
Sometimes, A Customer's Current Grinder Cannot Grind Fine Enough
To Achieve The Fundamental Rule. Therefore, To Increase The Pump
Pressure, We Suggest Creating Greater Resistance By Dosing A Slightly
Greater Amount of Ground Espresso Coffee. Sometimes, This Translates
Into A Superior Taste Profile for "Espresso Nirvana"..
Tamp Pressure
If You Are Using An Espresso Machine With A Pressurized Handle or
Pressurized Filter Basket, Just Apply A Light Tamp To The Ground
Coffee In The Basket. If You Are Using An Espresso Machine With
A Standard Handle and Filter Basket, A 30-50 lb Tamp Should Be Applied.
After Tamping, The Coffee Should Be Compacted Into A "Coffee
Puck". It Is Important To Maintain A Level Surface In The Basket.
An Un-level Surface Will Create A Path of Least Resistance for The
Water Being Pumped Into The Filter Basket. In Essence, The Same
Result Would Occur As If The Fineness of The Coffee Grind Was Inconsistent.
Remember To Remove Any Coffee Grinds That Remain On The Rim of
the Filter Basket. If These Coffee Grinds Remain, A Proper Seal
Will NOT Occur Between The Filter Basket and The Gasket In The Grouphead
of The Machine. This Will Result In Leaks Down The Outside Of The
Filter Handle and In A Weak Beverage Since Pressure Was Leaking
At The Point Of The Improper Seal.
Moment of Truth
Place The Filter Handle With The Tamped Ground Espresso Coffee Into
the Grouphead Of The Espresso Machine. Place The Preheated Cup Under
The Spout(s) of The Filter Handle. Check Your Clock For The Time
(In Seconds) and Press The Coffee Switch. Watch The Extraction.
Espresso Should Start Pouring From The Spout(s) Between 5 and 7
seconds After You Turned On The Coffee Switch. Make Sure Not To
Leave The Handle In Place Without Turning On The Coffee Switch Too
Long As The Hot Grouphead Will Burn The Grinds Before Extraction.
The Beginning Of The Extraction Is Usually Dark (Although Dependent
HIGHLY Upon The Beans You Are Using), And Then The Extraction Will
Turn Into A Golden Brown Cream That Pours Ever So Gently Into The
Base Of Your Cup. On Espresso Machines With Pressurized Handles
or Baskets, The Pour Will ypically Be Straight Down. On Espresso
Machines With Standard Handles And Baskets, The Pour Can Slightly
Curve On Filter Handles With A Dual Spouts. This Curvature Is Known
As "Mouse Tails."
When 2.0 to 2.5 Ounces Of The Espresso Has Been Extracted For A
Double Shot, Turn The Coffee Switch To The Off Position. Check The
Time (Seconds) On Your Clock. The Timing From the Points You Pressed
The Coffee Switch To The Time You Turned It Off Should Be Between
23 and 27 Seconds. Now, You May Have Extracted In A Lesser or Greater
Time. Just Taste The Espresso and See If You Like It.... If You
Do, Then Use That Timing As An Indication For Your "Espresso
Nirvana"!
We Have Assembled A Quick Reference Table To Make Your Adjustments
For Extractions Times Less Than 23 Seconds or Greater Than 27 Seconds.
Remember, There Are A Few Variables Which You Control. We Recommend
That You First Try To Adjust One Variable At A Time To Move Closer
To Your Goal of The Fundamental Rule!
| Science/Art
|
Espresso Extraction Shorter Than 23 Seconds or No Crema
|
Espresso Extraction Longer Than 27 Seconds or Too Bitter

| Preheat |
- Preheat Grouphead, Filter Handle, Filter Basket, and
Cups

Water Through Steam Wand (~6-8 ounces)

Putting It All Together - The Arte! Well, We've
Covered All The Fundamentals In "Reaching Espresso Nirvana"!
Now, It Is Up To You To Practice and Make Perfect With The Quality
Machine You Purchased from 1st-Cup
Coffee Company Equipment. Finally, You Can Make Slightly Different
Variations of Our Fundamentals To Acheive The Fundamental Rule.
For Instance, You Can Grind Slightly Finer and Tamp Slightly Less
To Achieve The Same Crema. However, You May Notice A More or Less
Favorable Taste From Making Those Changes. As We Referenced In the
Beginning, We Sure Hope It Tastes As Good As It Looks And Vice Versa.
Now, That We're All Set, Let's Go Look At Some Equipment!
Buon Appettito!!!!
