What are common mistakes to avoid when preparing espresso?

The selection of incorrect grind size, using stale coffee beans, and improper brewing time collectively highlights critical aspects of the espresso-making process that can significantly impact the final product.

Using the wrong grind size can result in either over-extraction or under-extraction of flavors from the coffee. A grind that is too coarse will lead to weak and underwhelming espresso, while a grind that is too fine can create a bitter taste due to over-extraction. Both scenarios fail to achieve the rich, balanced shot that is characteristic of well-prepared espresso.

Stale coffee beans can also ruin the flavor profile. Freshness in coffee is key to maximizing flavor, and stale beans can result in a dull or flat taste. Coffee starts losing its aromatic qualities soon after roasting, so using beans that have been stored properly and are still fresh is crucial.

Improper brewing time factors in the extraction process as well. Espresso typically requires a specific brewing time (around 25-30 seconds) to extract the right balance of flavors. If the brewing time is too short, the espresso will be weak, whereas too long can lead to bitterness.

By avoiding these common mistakes, you will improve your ability to prepare high-quality espresso that meets the standards expected in a coffee shop setting
