Coffee Beans

The differences between Arabica and Robusta, including growing conditions, caffeine levels, pest & disease resistance, flavor, and visual differences. Recognize key differences between Arabica & Robusta is can be from their taste and shape, The importance of coffee freshness, including The use of a sealed bag, ideally within one month after roasting and within a maximum of three months; Grinding coffee fresh (to order) within 1 minutes of preparing; another topic is how much importance of using fresh coffee beans and how to keep them fresh, you need good storage of beans in the hopper overnight or when not in use; for roasted bean Keeping lids on the bean hopper and dozer chamber; Store beans far away from air, moisture, light, and heat; Maintaining a stable temperature for roasted lower than 18 degrees and for green bean 60% moisture and 21 degrees for temperature and should be stable.

Workspace management

Maintains a hygienic and organized workspace that minimizes waste demonstrates the appropriate position for commonly used tools, eg tamp, pitchers/jugs, clothes, etc. you need to design your work area and workflow line to manage it in the busy time.

Grinding, Dosing and Tamping

The importance of keeping the work space clean, tidy and organized at all times The correct terminology to Identify correctly all key identify parts of grinder (hopper, espresso machine and adjustment collar, dosing grinder component parts chamber, fork, on/off switch) and espresso machine including switches (steam wand & tip, portafilter handle, group head, dispersion screen & gasket, drip tray, gauges, hot water spout, on/off switch, continuous/AV buttons) The acceptable range (per definition) of coffee used in espresso, and how distribution of coffee grounds affects extraction. The impact of tamping on distribution, and extraction flow,  it’s important to know demonstrates the basics of dosing, distribution and tamping and their impact on extraction is have a huge effect and has too many variables for making good espresso shot. The correct dosing action has an effect on achieving correct input with minimal waste. Demonstrates good dosing and distribution technique to keep dose consistent from one espresso to the next and to minimize channeling, Calibration of a grinder is the main part for choosing the tastes. The grinder should be calibrated to produce an espresso that falls within all standards. The grinder should be purged between adjustments, Demonstrates grind calibration, using a grinder with a dosing chamber OR an ‘on-demand’ grinder. How the grind affects shot times Identifies when a grind is incorrect and corrects it to produce espresso in 20-30 seconds. The correct use of a tamper to produce a flat and even surface on the tamped cake and to reduce repetitive strain injuries for a good tamping technique using a hand tamper

Extraction and Brewing

Espresso is a method of preparation that takes finely ground coffee, compacts it into a portafilter and forces hot water through it under pressure to make a concentrated coffee beverage , Sensory attributes are used to describe coffee, There may be regional variations to espresso and cappuccino parameters used in the traditional ways but normally I required just espresso with big basket as well as every one know with “double espresso basket”, there is no anymore single or double. just ESPRESSO : Dose depend of basket as you using, normally for specialty coffee it would be 18g – 20g or 21g , you should dose accurate size or 1+- for it. Brew ratio for espresso can be  1 / 1.5 , 1 / 2 or 1 / 2.5, mean for espresso 20 gr in and 40gr out is ½ which is standard and most of the time its work. Shot time: 20 – 30 seconds, you need analyze the key defining parameters of an espresso used within any examinations that you have , Tastes and describes attributes, such as aroma, body and flavor, of an espresso Chooses appropriate terms to describe flavor from the Specialty Coffee Taster’s Flavor Wheel

Try to understand how regional variations in parameters have effect on last flavor, There are five interdependent elements to brewing espresso: The bean / The barista / The machine / The grinder / The water , Lists of the five inter-dependent elements to brewing espresso which is in upside line , controlling them and know how they have effect on your last flavor is keep your consistency as well.

Preparation of the espresso machine requires:

  • Prepares the machine for use correctly and with appropriate equipment
  • Having separate cloths for steam wand, counter and portafilter

  • Warming (seasoning) group handles by pulling a minimum of 1 shot per group before dialing-in;
  • Stacking cups on cup warmer and saucers and spoons etc. next to the espresso machine
  • Preparation of espresso involves the following steps:
  • Remove portafilter from grouphead and flush group
  • Wipe basket clean and dry
  • Dose and distribute desired grams of coffee
  • Tamp consistently, level & ergonomically

  • Wipe basket clean and flush group (rinse optional)
  • Return portafilter to grouphead to keep preheated
  • Demonstrates the correct steps for preparing espresso according to SCA standards
  • Understanding of basic sensory qualities of
  • Under-extracted espresso (thin body, unbalanced flavor with high acidity, poor crema),
  • Over-extracted espresso (unbalanced flavor with high bitterness, poor crema)
  • An acceptable espresso (good body round and smooth, well balanced flavor (acidity, sweetness, bitterness), good visual crema which covers whole espresso (in line with coffee used)
  • Recognizes by sight and tastes the differences between under-extraction, over-extraction and acceptable extraction

 

Milk techniques

The importance of using fresh milk in maintaining foam standards:

  • Expired milk is unfit for consumption and should be discarded
  • The time milk is left out of the refrigerator should be minimized

  • Empty and clean pitcher before use
