Making filter coffee in Tamil Nadu involves several steps. Here are the typical steps involved:

Selecting the Coffee Blend:

A blend of Arabica and Robusta coffee beans is commonly used in Tamil Nadu. The beans are carefully chosen for their flavour and aroma. 

Arabica beans, known for their mild acidity and complex flavour notes, provide a smooth and aromatic base to the filter coffee. They add a subtle sweetness and hints of fruit or floral undertones.

Robusta beans, on the other hand, are known for their higher caffeine content and robust flavour profile. They bring a stronger, earthy taste and a fuller body to the coffee. Robusta beans also contribute to the rich crema that forms on top of the filter coffee. The specific ratio of Arabica to Robusta beans in the blend can vary, and different coffee roasters or households may have their own preferred ratios based on personal taste preferences.

The choice of coffee beans and their quality play a significant role in the final flavour of filter coffee in Tamil Nadu, and the balance between Arabica and Robusta beans helps create a distinctive and cherished taste that is loved by coffee enthusiasts in the region.

Roasting the Coffee Beans: The selected coffee beans are roasted to perfection. This process brings out the unique flavours and aromas of the beans. The level of roasting can vary based on personal preference, ranging from light to dark roast. Roasting plays a crucial role in the process of making filter coffee in Tamil Nadu. Here are the typical aspects of roasting involved:

Roast Level: In Tamil Nadu, coffee beans for filter coffee are commonly roasted to a medium to dark level. This roast level brings out the rich flavours and aromas desired in filter coffee. It is important to achieve an even roast to ensure consistency in the final brew.

Roasting Methods: Traditionally, coffee beans in Tamil Nadu are roasted using a pan or a drum roaster. In the pan-roasting method, a flat-bottomed pan is heated, and the beans are constantly stirred to ensure even roasting and prevent burning. In the drum roasting method, the beans are roasted in a rotating drum, allowing for more precise control over the roast.

Aromatics and Flavor Development: During the roasting process, the coffee beans undergo chemical changes that lead to the development of aromatic compounds and flavour profiles. The length of the roast affects the intensity of flavours, with longer roasts resulting in stronger, bolder flavours. The roasting process also reduces the acidity of the coffee, resulting in a smoother cup.

Cooling and Resting: After roasting, the coffee beans are immediately cooled to halt the roasting process and prevent over-roasting. The beans are then rested for a period of time, typically 24 to 48 hours, to allow for the release of carbon dioxide and the development of flavours before grinding and brewing.

Grinding the Coffee Beans: The roasted coffee beans are then ground to a medium-coarse consistency. This ensures that the coffee is not too fine, allowing for proper extraction of flavours during brewing. Grinding the coffee beans is a crucial step in making filter coffee in Tamil Nadu. Here's how it is typically done:

Coarse Grinding: The roasted coffee beans are ground to a medium-coarse consistency. This coarser grind allows for proper extraction of flavours during the brewing process.

Traditional Grinding Methods: In Tamil Nadu, traditional grinding methods are often favoured to maintain the authenticity of the process. One such method is using a manual grinder known as "Ammikal" or "Ammi Kal" in Tamil. It consists of a large stone slab with a cylindrical stone roller. The beans are placed on the slab, and the roller is manually rotated to crush the beans into a coarse powder.

Electric Grinders: While traditional grinding methods are still cherished, electric grinders have gained popularity for their convenience. Electric burr grinders or blade grinders can be used to achieve a consistent medium-coarse grind. It is essential to grind the beans just before brewing to preserve the freshness and aroma.

Quantity: The amount of coffee beans used for grinding depends on personal preference and the desired strength of the brew. Generally, a ratio of one to two tablespoons of ground coffee per cup of water is a good starting point.

Preparing the Filter: The traditional filter used for making filter coffee in Tamil Nadu is called a "Davara Set" or "Madras Filter." It consists of a cylindrical metal filter with two compartments. The upper compartment, called the "upper dabara," is where the coffee grounds are placed, and the lower compartment called the "lower dabara," collects the brewed coffee decoction.

To prepare the filter, the upper compartment is detached from the lower compartment. A perforated disc with tiny holes is placed at the bottom of the upper compartment. This disc acts as a sieve to ensure a smooth flow of water through the coffee grounds.

Next, finely ground coffee is added to the upper compartment. The coffee grounds are distributed evenly and gently tapped to create a uniform bed. It is essential to maintain the right level of compactness to allow the water to pass through the coffee and extract the flavours effectively.

Once the coffee grounds are in place, the upper compartment is reattached to the lower compartment, forming a seal. The filter is now ready to start the brewing process, where hot water is poured over the coffee grounds, allowing the decoction to slowly drip down into the lower compartment. This process ensures a strong and flavorful brew, characteristic of Tamil Nadu's filter coffee.

The preparation and handling of the filter require skill and finesse, as even slight variations in the distribution of coffee grounds or water flow can impact the taste and quality of the final brew. The art of preparing the filter reflects the attention to detail and dedication that goes into making an authentic cup of filter coffee in Tamil Nadu.

Adding Coffee Grounds: Adding the coffee grounds is a critical step in the process of making filter coffee in Tamil Nadu. Once the coffee beans have been roasted to perfection, they are carefully ground to a medium-coarse consistency. This specific grind size allows for optimal extraction of flavours during the brewing process. In traditional Tamil Nadu filter coffee preparation, a cylindrical metal filter known as a "Davara Set" is used. The upper compartment of the filter is filled with the freshly ground coffee. The coffee grounds are then gently tapped to create an even layer, ensuring uniform extraction. This meticulous process sets the foundation for the rich and aromatic brew that is characteristic of Tamil Nadu's filter coffee.

Pouring Hot Water: Once the coffee beans have been ground to a medium-coarse consistency, the next step in making filter coffee in Tamil Nadu is pouring hot water over the coffee grounds. This step requires precision and patience. Boiling water is heated separately, ensuring it reaches the ideal temperature, typically around 90 to 95 degrees Celsius (194 to 203 degrees Fahrenheit).

With the filter set in place, hot water is poured slowly over the coffee grounds. The water seeps through the grounds, gradually making its way down to the lower compartment of the filter. This slow and controlled process allows for the optimal extraction of flavours, resulting in a rich and flavorful decoction.

As the water percolates through the coffee, it carries the essence and oils from the beans, creating a strong and aromatic brew. The decoction that collects in the lower compartment of the filter is dark and concentrated, forming the base of the authentic Tamil Nadu filter coffee.

This careful and deliberate pouring of hot water over the coffee grounds is essential in achieving the distinctive taste and aroma that Tamil Nadu filter coffee is known for. It is a ritualistic process that reflects the artistry and dedication to preserving the traditional brewing techniques.

Mixing the Decoction and Milk: This decoction is what gives Tamil Nadu's filter coffee its distinct flavour and strength. The decoction is carefully separated from the residue, resulting in a strong and flavorful brew.

Next comes the crucial step of mixing the decoction with milk. The milk used is typically fresh and full-fat, lending a creamy texture to the coffee. The decoction is poured into a small tumbler, followed by an equal amount of hot milk. The two liquids are mixed by pouring them back and forth between the tumbler and a small metal container called a "dabarah." This process not only combines the decoction and milk but also helps to cool down the coffee to a drinkable temperature.

Sweetening: The use of jaggery as a sweetener in filter coffee is deeply rooted in Tamil Nadu's traditional culinary practices. It not only adds sweetness but also imparts a distinct caramel-like undertone to the coffee, making it a truly enjoyable experience. Many households in Tamil Nadu have a dedicated container filled with jaggery cubes specifically for making filter coffee. This reflects the significance of this sweetener in the daily lives of Tamil Nadu's coffee enthusiasts.

Serving: Traditionally, filter coffee is served in a stainless steel tumbler and a wide-brimmed bowl called the "dabarah." The coffee is poured back and forth between the tumbler and dabarah to create a frothy layer on top. This process, known as "dabara style," enhances the aroma and presentation of the coffee.

By following these steps, one can enjoy a cup of authentic and flavourful filter coffee, a cherished tradition in Tamil Nadu.
