## Quick answer

South Indian **filter coffee** starts with a strong decoction from a metal filter. **Warm milk** turns it into the finished drink. Measure **a small amount** first, as the decoction’s strength affects the final **balance**.

## Key takeaways

- South Indian filter coffee starts with a strong decoction from a metal filter.

- Add ground coffee to the upper chamber of a South Indian filter and level it gently.

- Combine the decoction with hot milk to taste, then sweeten if desired.

## Make the decoction

 

Add **ground coffee** to the upper chamber of a South Indian filter and level it gently. Pour hot water over **the grounds**, place the perforated insert and **lid**, then let the coffee collect below. The wait depends on **the filter** and grind; follow the method you use rather than forcing the brew.

 

## Mix with milk and serve

 

Combine the decoction with hot milk to taste, then sweeten if desired. **A small amount** of decoction makes a mild cup; using more creates a stronger coffee flavor. Some traditional **serving** styles pour the drink between vessels to mix and aerate it, but use heat-safe equipment and take care with hot liquid.

 

## Choose the coffee blend

 

Some South Indian filter coffees use a coffee-and-chicory blend; others contain coffee alone. Check **the label** so you know what you are buying and can adjust the brew. Our guide to [reading coffee **labels**](https://www.coffeejay.com/en/learn/guides/coffee-basics/read-a-coffee-bag-label/) explains how to check blends, and [milk **texture**](https://www.coffeejay.com/en/learn/guides/milk-drinks/dairy-milk-for-coffee-foam/) can help if you want a smoother finish.

 

## Adjust decoction and milk separately

 

Make the decoction with **the filter**’s directions, then add it to hot milk gradually. More decoction creates a stronger coffee flavor; more milk softens it. Keep **the proportions** steady while you compare a new blend so you can tell whether the coffee or **the serving** changed the result.

 

Some **serving** styles mix the drink by **pouring** between vessels. If you try this, use two heat-safe containers with enough **room** and pour carefully to avoid splashing. Stirring with a spoon is also an option; choose the method that feels safe and comfortable in your kitchen.

 

### Check the blend before brewing

 

If chicory is included, expect a different cup from coffee alone. Read the package and use a measured starting **recipe** before adjusting strength or **sweetness**.

 

## Plan the decoction before serving

 

The metal **filter** takes time to collect its decoction, so start it before heating milk and preparing cups. The timing depends on the filter, **grind**, and amount of coffee. Follow **your brewer**’s directions and avoid pressing the grounds down unless the maker instructs you to do so.

 

Keep the amount of decoction consistent while you **compare** different blends. Once the coffee is brewed, add milk gradually and sweeten only if desired. This makes it easier to find **a balance** without masking the difference between coffee-only and coffee-and-chicory blends. Serve it immediately while warm. Adjust each cup separately if guests prefer different strengths. Avoid filling cups to the brim.
