Types of tea and where grown

There are various types of tea, and they are typically classified into categories based on how they are processed. The main types of tea include:

  1. Green Tea: Made from oxidised leaves, preserving the natural antioxidants. Commonly grown in China and Japan.

  2. Black Tea: Fully oxidised leaves, resulting in a robust flavour. Major producers include India, China, and Africa.

  3. Oolong Tea: Partially oxidised leaves, falling between green and black tea in terms of oxidation. Grown in China and Taiwan.

  4. White Tea: Minimal processing, often made from young leaves and buds. Primarily produced in China.

  5. Pu-erh Tea: A fermented tea from Yunnan province in China, known for improving with age.

Tea is grown in various regions worldwide, with specific climates and altitudes influencing the flavour profiles. While China and India are significant producers, other countries like Japan, Sri Lanka, Kenya, and Taiwan also contribute to the global tea market.

The general steps involved in the production of tea

  1. Cultivation and Harvesting:

    • Tea plants are cultivated, typically in plantations. The leaves are harvested, and the timing is crucial for determining the type of tea.

  2. Withering:

    • The harvested leaves undergo withering, a process where they lose moisture. This is often done naturally or with the help of fans.

  3. Rolling:

    • The withered leaves are rolled to break their cell walls. This releases enzymes and initiates oxidation.

  4. Oxidation or Fermentation:

    • The rolled leaves are spread out for oxidation. The extent of oxidation determines the type of tea—green tea is unoxidized, black tea is fully oxidized, and oolong tea is partially oxidized.

  5. Fixation:

    • The oxidation process is halted by heat treatment, often through steaming (common for green tea) or pan-firing. This step helps preserve the desired characteristics of the tea.

  6. Drying:

    • The leaves are dried to reduce moisture content, ensuring the tea is stable and won't spoil.

  7. Sorting:

    • The tea leaves are sorted based on size, shape, and quality. This step helps ensure consistency in the final product.

  8. Grading:

    • Teas are graded based on quality factors such as leaf size, color, and appearance. This step is crucial for the commercial market.

  9. Packing:

    • The sorted and graded tea is packed into various containers, including bags, boxes, or loose-leaf packaging, ready for distribution.

  10. Tasting and Quality Control:

    • Tea professionals may sample and taste the tea to ensure it meets quality standards before it's packaged for sale.

These steps can vary slightly depending on the type of tea and regional traditions.

The steps in the production of coffee

  1. Planting:

    • Coffee cultivation begins with planting coffee seeds or seedlings. The choice of the coffee variety and the conditions of the soil play a crucial role in this stage.

  2. Growing and Maintenance:

    • Coffee plants require specific conditions to thrive, including the right amount of sunlight, rainfall, and proper care. Farmers need to manage pests and diseases that can affect the coffee plants.

  3. Harvesting:

    • The time it takes for a coffee plant to produce cherries varies, but typically it takes several years. Once the coffee cherries are ripe, they are ready for harvesting. In many regions, this is done by hand, selectively picking only the ripe cherries.

  4. Processing:

    • After harvesting, the coffee cherries need to be processed to extract the beans. There are two primary methods:

      • Dry Processing: The cherries are spread out in the sun to dry, and the beans are then extracted.

      • Wet Processing: The cherries are pulped to remove the outer skin, and the beans are fermented and washed before drying.

  5. Milling:

    • The dried beans are then hulled and milled to remove the parchment layer and any remaining husk, leaving behind the green coffee beans.

  6. Sorting and Grading:

    • The green beans are sorted and graded based on size, weight, and quality. This step ensures that only high-quality beans make it to the next stages of production.

  7. Roasting:

    • The green coffee beans are roasted to develop the characteristic flavors and aromas of coffee. Roasting is a critical step that significantly influences the final taste.

  8. Grinding:

    • Roasted coffee beans are ground into a coarse or fine powder, depending on the brewing method. The grind size affects the extraction of flavors during brewing.

  9. Brewing:

    • Finally, the ground coffee is brewed to produce the beverage. There are various brewing methods, including drip brewing, espresso, French press, and more.

  10. Packaging:

    • The finished coffee is packaged for distribution and consumption. This can involve grinding and packaging the coffee in various forms, such as whole beans, ground coffee, or coffee pods.

Each step in the production process contributes to the final taste and quality of the coffee.

Cocoa



Types of cocoa and where grown

Cocoa is primarily grown in tropical regions near the equator. The main types of cocoa beans are:

  1. Forastero: This is the most widely cultivated variety, known for its hardiness and robust flavour. It is grown in West Africa, particularly in countries like Ivory Coast, Ghana, and Nigeria.

  2. Criollo: Considered a high-quality variety with a delicate flavour profile, Criollo beans are mainly cultivated in Central and South America, including countries like Venezuela, Ecuador, and Mexico.

  3. Trinitario: This is a hybrid variety that combines features of both Forastero and Criollo. Trinitario cocoa is grown in various regions, including Trinidad, Tobago, and other parts of the Caribbean, as well as some countries in Central and South America.

These regions provide the ideal climate and conditions for cocoa cultivation, with warm temperatures, high humidity, and well-distributed rainfall.

Steps in production of cocoa

The production of drinking cocoa involves a different process compared to the production of chocolate. Here are the steps:

  1. Harvesting and Opening the Pods:

    • Similar to chocolate production, cocoa pods are harvested and opened to extract the cocoa beans.

  2. Fermentation:

    • The extracted beans, still surrounded by some pulp, undergo fermentation, contributing to the development of flavour.

  3. Drying:

    • After fermentation, the beans are dried to reduce moisture content.

  4. Roasting:

    • The dried beans are roasted to enhance the cocoa flavour and aroma.

  5. Winnowing:

    • The roasted beans are winnowed to remove the outer shell, leaving behind the cocoa nibs.

  6. Grinding:

    • The cocoa nibs are ground into a coarse powder.

  7. Pressing:

    • The ground cocoa is pressed to separate cocoa solids from cocoa butter.

  8. Blending and Grinding:

    • The separated cocoa solids are blended with other ingredients like sugar, milk powder, and sometimes additional cocoa butter.

    • The mixture undergoes further grinding to achieve a smooth consistency.

  9. Dutching (Optional):

    • Some drinking cocoa is subjected to a process called Dutching, where it is treated with an alkaline solution to modify its colour and taste.

  10. Packaging:

    • The final drinking cocoa product is packaged for distribution and consumption.

  11. Preparation:

    • To enjoy drinking cocoa, consumers typically mix the powdered cocoa with hot water or milk.

The key difference between drinking cocoa and chocolate production lies in the additional ingredients and the level of processing. Drinking cocoa is often more straightforward and doesn't involve the extensive steps of chocolate conching and tempering.

Australian cocoa

In Australia, cocoa is not a major commercial crop due to the country's climate, which is not well-suited for cocoa cultivation. Cocoa trees thrive in tropical regions near the equator, where they require consistently warm temperatures, high humidity, and ample rainfall.

However, there are efforts and experiments to grow cocoa in certain regions of Australia with more suitable conditions. These efforts are often limited to specific areas with climates that somewhat resemble tropical conditions. Queensland, particularly in the far north of the state, has been involved in experimental cocoa cultivation.

In these experimental projects, varieties of cocoa that are better adapted to subtropical conditions are often selected. The goal is to explore the possibility of establishing a cocoa industry in Australia, taking advantage of niche markets and the growing interest in locally produced and unique agricultural products.

It's worth noting that while there may be some limited cocoa cultivation experiments, Australia is not a significant global player in the cocoa industry. The majority of the world's cocoa is produced in tropical regions, primarily in West Africa, South and Central America, and Southeast Asia.
