Q&A

• How does overheating affect the taste of coffee?

  Overheating coffee can result in a burnt taste as it alters the chemical composition of the brew, impacting its overall flavor and aromatic qualities.

• What defines espresso?

  Espresso is a small, strong cup of coffee brewed under high pressure with finely ground coffee, resulting in a concentrated and bold flavor profile.

• What is the health impact of excessive coffee consumption?

• How can coffee be stored for long-term preservation?

  Coffee beans can be stored for long-term preservation by freezing them in an airtight package to maintain their freshness and flavor over an extended period.

• What is the recommended coffee to water ratio for brewing?

  The recommended coffee to water ratio for brewing coffee typically ranges from 1:15 to 1:17, meaning 1 part coffee to 15-17 parts water, depending on preferred strength.

• Where is the best climate for growing coffee?

  The best climate for growing coffee is in regions near the Equator, within the tropical belt known as the 'coffee belt.'

• What is the difference between cold brew and iced coffee?

  Cold brew is made by steeping coffee grounds in cold water for an extended period, producing a smoother, less acidic coffee. Iced coffee is coffee brewed with hot water and then cooled down with ice, retaining more of the coffee's original flavor profile.

• What are the reasons for adding milk and sugar to coffee and tea?

  Milk and sugar are often added to coffee and tea to balance out acidity, reduce bitterness, or enhance the flavor. However, high-quality coffee should already possess a natural sweetness.

• What are the effects of coffee on digestion?

• How can espresso be made without a machine?

  Espresso can be made without a machine using alternative coffee equipment such as an AER press and a Moka pot. These methods allow for the creation of espresso-like coffee at home.

• What is the ideal temperature for brewing and drinking coffee?

  The ideal temperature for brewing coffee is close to the boiling point, while for drinking, it should be closer to body temperature to avoid scalding and to fully savor the flavor.

• How does the decaffeination process work?

  The decaffeination process typically removes 99.5% of caffeine from coffee beans. There are various methods such as the Swiss Water Process and the use of solvents to decaffeinate coffee.

• Is good instant coffee available?

  Yes, good instant coffee is made from high-quality raw materials, ensuring a satisfying and convenient coffee experience.

• How do different roasts affect caffeine content?

  Different roasts affect caffeine content due to variations in bean density. Lighter roasts generally have more caffeine while darker roasts have slightly less.
