The filter coffee that I have purchased contains 53% Coffee and 47% Chicory.

Since I don't have a machine yet, what I did is as follows:

Spoon measure: 6 ml

1. I put heaped Coffee spoon in a steel glass.
2. Added 60ml boiling water to the same, stirred and kept in untouched for 6 minutes.
3. Then I added 200ml hot milk to the same with 2 spoons sugar.
4. Filtered the mixture using a strainer.

The result was **NOT** strong Coffee.

Questions: 

1. Do I need a Coffee with less amount of Chicory?
2. Do I need to add more Coffee OR steep the same amount of Coffee for a much longer duration?
