The barista plays a crucial role in creating a delicious and appealing cup of coffee by mastering the principles of extraction and honing exceptional skills.

• Incorrect Temperature: Water that is too hot can increase the amount of bitter compounds extracted from the coffee, while water that is too cool can result in under-extraction, leading to a bitter, dry, and bland cup.
  

• Improper Extraction Time: Insufficient extraction time can result in coffee that lacks flavor, sweetness, and body, while over-extraction can produce bitterness.
  

• Incorrect Pressure Adjustment: Especially for espresso, improper pressure adjustment can lead to poor-quality coffee due to under or over-extraction.
  

• Wrong Grind Size and Grinder Consistency: Poor grind size and inconsistent grinding can lead to uneven extraction, resulting in an imbalanced cup of coffee.
  

• Improper Coffee-to-Water Ratio: An incorrect coffee-to-water ratio can affect the quality of extraction, resulting in coffee that is either too strong or too weak.
  

• Neglecting Coffee Machine Maintenance: A coffee machine that is not cleaned and maintained properly can reduce extraction performance and quality.
  

In summary, not understanding the principles of coffee extraction can lead to various issues and result in a poor cup of coffee.

It all depends on the brew 😜
