http://www.ncausa.org/i4a/pages/index.cfm?pageid=71>Water Temperature During Brewing>Your brewer should maintain a water temperature between 195 - 205 degrees Fahrenheit for optimal extraction. Colder water will result in flat, underextracted coffee while water that is too hot will also cause a loss of quality in the taste of the coffee. If you are brewing the coffee manually, let the water come to a full boil, but do not overboil. Turn off the heat source and allow the water to rest a minute before pouring it over the grounds.Basically get water to a hard boil, then let it sit off the fire until it stops bubbling, it'll be just about 210 then. And it'll lose heat while pouring it through the air.
I'd rather have the water be too hot than cold, because anything lower than 195 gets really weak if you try to brew a lot.
Keurig machines brew at 192 max, so they are only good for the 6 oz brew.
