Here is my contribution. This is what I have learnt from experience:
1. while brewing coffee, hot boiling water has to be poured on the coffee powder and not vice versa.
Normally TB community(of Tanjore origin) doesn't put coffee powder in to boiling water and only boiling water in the filter containing coffee powder
2. the coffee you make will depend to a great extent on the kind of milk you use. whole milk will be ideal. toned milk because of reduced fat tastes differently and spoils the experience.
Only fresh cow milk is used
3. coffee has to be taken when it is still hot.
Correct
4. take coffee slowly, not in a few gulps quickly.10 minutes for one tumbler will be ideal.
Offcourse with foam
5.preparation of t he coffee powder has to be done carefully. Generally only two varieties of seeds are used(though there is a third variety called robusta) in various proportions depending on individual preferences. The plantation variety of seeds give the unique bitter taste while peaberry seeds gives the flavour. I use these two varieties in equal proportion in the mix.Some times i go for 60% plantation and 40% peaberry to get better taste.
Normally Plantation A and Plantation PB in equal quantities. `PB'will give flavour and `A' will give volume.
6.the powder has to be ground in such a way that it does not become very fine in consistency. If I had the facility I would have measured the size and would have given it in microns.
In my younger days, myself and my brother/sisters use to wake up in the early morning and grind fresh powder using hand grinding machine.
7.Chicory is extraneous to coffee and so i dont add it.
Chicory has to be avoided totally. It will spoil the taste
Cheers and happy coffee times.
