Coffee, making thereof

Your coffee is good when you can enjoy it black.  If you have to do the cream and sugar thing, it means your coffee is coming out bitter.
Step 1 in making good coffee is a clean coffee maker.  Brewing coffee releases all sorts of oils and fragrances which stick the the coffee maker innards.  After time ( a few hours) the oils turn rancid and make the next pot taste bitter.   You need a coffee maker that is easy to clean, inside and out.  The French press is good,  it comes completely apart and you can get inside it with a wash rag or a sponge.  The Silex vacuum coffee makers are good, all glass,  easily cleaned.  Percolators are bad, the inside of that perk tube  is just plain uncleanable. 
Step 2 is good coffee.  Shop around,  try a can of the expensive stuff.  Try some cans of the supermarket brand cheap stuff.  Keep some notes so you can remember what you like.  Up here, Surefine 100% Columbian $4.50 a can makes very good coffee, as good or better than some $10 a can coffee from Dunkin, Green Mountain and others .
   I don't do the grind it from beans thing.  I buy ground coffee and keep it in the fridge after opening it.  Works for me.
   Put in one heaping tablespoon of coffee for each cup of water.  Give the coffee at least four minutes to brew.  Try a little salt with the coffee.  Sometimes salt improves the coffee, the US Navy swears by it,  sometimes not so much.
