I read something yesterday, that said not to boil water before brewing
coffee with it. Something about it taking out the micro-bubbles of air
in the water, which actually help the brewing flavor?
Here:

A single shot of "True Espresso," as defined in the specialty coffee
trade, requires a precise weight of finely ground coffee (7 grams) to be
tightly packed (tamped) into a filter holder so that hot water (not-
quite-boiling water, between 195 and 205 F -- 88 and 92 degrees C;
boiling water or steam will utterly incinerate coffee's delicate
essences), moving under at least nine atmospheres of pressure (at least
130 pounds per square inch -- or some unknown number of ergs, Newtons,
Joules or kiloPascals), will take 20 to 30 seconds to extract exactly
one fluid ounce of the magical liquid.

TEMPERATURE - for brewing coffee the recommended temperature for proper
extraction is between 197-204 degrees. Do not boil the water for it
loses dissolved air that can leave coffee flat. If the water is too
cool, the brew will be under-extracted and have a poor taste.

Do not boil the water. Coffee is best made with water that has not
boiled and is slightly below boiling point.
