Interview Questions for Coffee Production

Coffee processing is a journey from cherry to cup, and it’s fascinatingly complex. It begins with harvesting ripe coffee cherries. These cherries are then processed to separate the beans from the fruit. There are three main processing methods:

• Washed/Wet Process: Cherries are depulped, fermented, washed, and dried. This method produces a cleaner, brighter cup profile.
• Natural/Dry Process: Cherries are dried whole in the sun, then depulped. This results in a fruitier, sweeter cup with more body.
• Honey Process: A hybrid method where some of the mucilage (sticky layer) is left on the beans during drying, resulting in a balance between the washed and natural processes.

After drying, the beans are hulled (removing the parchment layer) and then sorted and graded. Finally, they are ready for export and further processing, such as roasting.

There’s a vast world of coffee varieties, each offering unique flavor profiles. Arabica and Robusta are the two major species, with numerous cultivars within each.

• Arabica: Generally known for its higher quality, nuanced flavors, and lower caffeine content. Examples include Typica (a classic with balanced acidity and body), Bourbon (similar to Typica but often fruitier), Geisha (renowned for its floral and tea-like notes), and Caturra (a high-yielding variety with a sweet, clean taste).
• Robusta: Offers a stronger, bolder flavor with higher caffeine and a more robust body. It’s often used in espresso blends or as a cheaper option.

Flavor profiles vary tremendously depending on factors like terroir (soil, climate, altitude), processing method, and roasting style. For example, an Ethiopian Yirgacheffe Arabica is famous for its bright citrus acidity and floral aromas, whereas a Sumatran Mandheling is known for its earthy, full-bodied profile and low acidity.

Coffee bean quality is a complex interplay of various factors. Think of it as a recipe with many crucial ingredients:

• Varietal: The genetic makeup of the coffee plant determines baseline flavor characteristics.
• Terroir: Altitude, soil composition, rainfall, and sunlight all significantly impact bean development and flavor.
• Farming Practices: Proper cultivation, harvesting techniques (selective picking of ripe cherries is crucial), and post-harvest processing methods are critical.
• Storage: Proper storage after processing prevents degradation and preserves quality. Beans should be stored in cool, dark, airtight containers to maintain freshness.

A single flaw in any of these areas can impact the final cup quality, demonstrating the interconnectedness of factors from farm to cup.

Ensuring consistent coffee quality demands meticulous attention throughout the supply chain. This requires:

• Strict Quality Control at Each Stage: From cherry selection to milling and roasting, regular quality checks are vital to identify and correct any deviation from standards.

Imagine a symphony orchestra: every musician must play their part perfectly for a harmonious performance. In coffee production, every step needs to be consistent to achieve the desired final product.

Coffee roasting is a crucial stage where green coffee beans are transformed into the aromatic, flavorful beans we know and love. The process involves heating beans to specific temperatures, triggering chemical changes that drastically impact flavor and aroma.

During roasting, beans undergo several stages: drying, browning, and development. The roasting profile (temperature and duration) dictates the final flavor. Too short a roast yields under-developed flavors, while over-roasting leads to bitterness and burnt notes. Key factors to manage include:

• Temperature: Precise temperature control is essential for achieving the desired roast level.
• Time: The roasting duration dictates how the beans develop their flavors.
• Bean Type: Different bean varieties react differently to the roasting process, requiring tailored roasting profiles.

Think of roasting as cooking: a slight change in the temperature or time can dramatically change the outcome.

Roasting levels are categorized by color and flavor characteristics. While descriptions can vary, common levels include:

• Light Roast: Beans are light brown, with high acidity, delicate flavors, and a more vibrant aroma.
• Medium Roast: A balance of acidity and body, with more pronounced flavors than light roasts.
• Medium-Dark Roast: Stronger flavors, full body, less acidity, and a more intense aroma.
• Dark Roast: Dark brown beans with reduced acidity, bolder flavors, and often a smoky or bittersweet taste.

The choice of roast level depends on personal preference and the type of coffee being brewed; some beans benefit from lighter roasts to highlight their delicate flavors, while others excel with darker roasts that emphasize body and intensity.

Cupping, or sensory evaluation, is a standardized method to assess the quality of coffee. It involves a systematic approach to evaluating various sensory attributes:

• Aroma: The dry and wet aroma of the ground coffee are assessed.
• Flavor: The taste, including acidity, sweetness, bitterness, body, and aftertaste, is evaluated.
• Acidity: The brightness and liveliness of the coffee.
• Body: The mouthfeel, how the coffee feels in your mouth.
• Aftertaste: The lingering flavor after swallowing.

Professionals use a specific cupping protocol: grinding beans, blooming, and slurping the coffee to assess these aspects, providing a comprehensive evaluation of coffee quality. Cupping is essential for quality control, sourcing, and product development.

Identifying defects in green coffee beans is crucial for ensuring quality. It’s a multi-sensory process, combining visual inspection with the occasional use of touch and smell. We look for defects broadly categorized as primary and secondary defects.

• Primary Defects: These affect the bean’s inherent quality and are usually caused during the growing or processing stages. Examples include: Black beans (overripe or severely damaged), Broken beans (cracked or split), Immature beans (greenish, under-developed), and Insect damage (holes or webbing). The presence of these defects significantly impacts the final cup quality.

• Secondary Defects: These are less severe, often affecting the bean’s appearance but not necessarily its internal quality. Examples include Quakers (hard, dense beans that don’t roast properly), Stony beans (hard, heavy beans, usually indicating mineral content), and Damaged beans (with minor cracks or blemishes). Though less detrimental, high percentages of secondary defects can still indicate issues in processing or storage.

We typically use a combination of manual sorting, using specialized sieves to separate beans by size, and electronic color sorters, which use cameras and sensors to identify and remove defective beans based on their color and shape. The percentage of defects is meticulously recorded and plays a significant role in determining the bean’s overall grade and price.

Coffee production faces numerous challenges, many intertwined and influenced by climate change.

• Climate Change: Erratic rainfall, extreme temperatures, and increased pest infestations directly impact yield and quality.
