A. Coffee Bean Variety

The type of coffee bean used plays a significant role in determining the caffeine content of espresso. Generally, there are two main species of coffee beans:

1. Arabica
2. Robusta

Bean Type	Caffeine Content	Flavor Profile
Arabica	Lower (1.2-1.5%)	Smooth, complex
Robusta	Higher (2.2-2.7%)	Strong, bitter

Robusta beans contain nearly twice the amount of caffeine compared to Arabica beans. This difference can significantly impact the final caffeine content of the espresso shot.

B. Roast Level

Contrary to popular belief, the roast level of coffee beans affects caffeine content:

• Light roasts: Contain slightly more caffeine
• Dark roasts: Contain slightly less caffeine

This occurs because the roasting process breaks down caffeine molecules. However, the difference is minimal and often negligible in a single shot of espresso.

C. Grind Size

The size of coffee grounds influences the extraction process and, consequently, the caffeine content:

1. Fine grind: Increases surface area, leading to more caffeine extraction
2. Coarse grind: Decreases surface area, resulting in less caffeine extraction

For espresso, a fine grind is typically used, which contributes to its higher caffeine concentration compared to other brewing methods.

D. Extraction Time

The duration of the extraction process directly affects the amount of caffeine in the final espresso shot:

• Shorter extraction time: Less caffeine extracted
• Longer extraction time: More caffeine extracted

However, it’s important to note that over-extraction can lead to bitter-tasting espresso. The ideal extraction time for a standard espresso shot is typically between 25-30 seconds.

These variables interact with each other, making it challenging to predict the exact caffeine content of an espresso shot without proper measurement. For instance, a longer extraction time with Robusta beans will yield a higher caffeine content compared to a shorter extraction with Arabica beans.
