The question asks for the ideal annual rainfall range required for Arabica coffee cultivation. This is a factual question related to agricultural geography and crop requirements. We need to recall the specific climatic conditions suitable for Arabica coffee.
Correct Option: C) 1500 to 2500 mm
The question asks about the typical annual rainfall requirement for Robusta coffee cultivation. To answer this, we need to recall the ideal climatic conditions for Robusta coffee.
D) 1000 to 2000 mm is the typical annual rainfall requirement for Robusta coffee. This range ensures adequate moisture for the plant's growth and development.
The question asks to identify the coffee variety with a higher caffeine content among the given options. This requires knowledge of the characteristics of different coffee species.
Correct Option: A) Robusta
Robusta coffee beans are known to contain significantly more caffeine than Arabica beans. This higher caffeine content is one of the distinguishing characteristics of Robusta, along with its stronger, more bitter flavor profile and greater resistance to diseases and pests.
The question asks about the approximate caffeine content in Arabica coffee beans by dry weight. This is a factual recall question related to the chemical composition of different coffee varieties. Knowing the typical caffeine percentages for common coffee types like Arabica and Robusta is essential.
B) About 1.2 to 1.5%. Arabica coffee beans are known to contain approximately 1.2% to 1.5% caffeine by dry weight. This relatively lower caffeine content, along with its complex flavor profile, contributes to its popularity.
The question asks about the approximate caffeine content in Robusta coffee by dry weight. This is a factual question requiring knowledge of the typical chemical composition of different coffee bean varieties.
D) About 2.2 to 2.7% is the correct answer. Robusta coffee beans are known for having a significantly higher caffeine content compared to Arabica beans. The typical range for Robusta is indeed around \(2.2\%\) to \(2.7\%\) by dry weight, sometimes even reaching \(4.5\%\) in certain varieties.
The question asks to identify the coffee variety known for a milder, sweeter, and more aromatic flavour. This requires knowledge of the characteristics of the main coffee types, Arabica and Robusta.
C) Arabica is the coffee variety known for its milder, sweeter, and more aromatic flavour profile. It is widely preferred for specialty coffee due to its complex taste and pleasant aroma.
