I thought that I was taking the water temp into account when I would preheat the water and then let it rise to 205*F before placing the upper bowl with the coffee in it.  Apparently the temp drop from the added mass of the additional glass was dropping the water temp below the 195*F limit.  

Since reading this thread, Iíve taken to preheating the water and then letting it rise to the upper chamber where I check the temp.  Once it has reached 195*, in go the grounds.  Much better results.  Thanks for the heads up!  I just have to get a handle on keeping the temp below 208 and not let the steam from below keep the temp rising before my 3 min. is  up.

I can understand why the instructions do not address this.  First off, not everyone wants to make as much of a ritual out of the coffee brewing experience as some on this site do.  And Iím sure that compared to the majority of coffee that is being consumed out there, even the slightly sour brew that is produced by using the instructions is better by far already.

Man, I learn something new every day on these boards that improves my coffee!

I took some measurements myself this morning, similar to Dan's approach.  Decided to not pre-heat the water.  I wanted to see how long it would take from start-to-finish with no shortcuts.

Assembled the pot (no coffee in the upper chamber) and placed it over medium heat at 8:38AM.

When the upper chamber was half full, the temp read 169 F (76.1 C).

When the upper chamber was completely full and "bubbling", the temp still only read 181 F (82.7 C).

So I decided to wait (and time) before adding the grinds.  So I waited.

And waited.

And waited.

A full 6:53 minutes later, the water temp in the upper chamber had finally hit 195 F (90.5 C) so I dumped the grinds in, stirred, steeped for 2 minutes and pulled it off the heat for it's journey downward (about another minute).

Total time from putting the pot on until I was drinking coffee?  31 minutes.

I guess my question to some of you now, is can I (should I) increase the heat to med-hi or hi to get the upper chamber water closer to 200 (and faster)?  I have an electric cooktop.  I am worried that too high of heat will crack the carafe.  

I watched the small amount of water in the bottom chamber very carefully while I was waiting for the upper chamber water to get hot enough.  It never dried up downstairs but it did diminish to dangerously close levels, IMO.  The other interesting thing I noted was that after a few minutes, the water in the upper chamber stopped bubbling altogether (but did slowly get hotter).

I will say, though, that the cup I'm sipping on right now is by far the best I've had yet from my vacpot!

I thought about that a bit since i overpaid just to get an original 6 cup cory but i'm sorta of one of those Damn the torpedoes types.

Starting with near boiling water, if available, will cut the time a lot. The burner i use is the solid cast element, electric medium wattage (don't really know the true value)  set to the highest point on the dial. I think my total time is in the 12 minutes range.

It does look a bit scary to see the water level drop to 1/2" in the lower chamber but so far i've had no damage.

Remembering back to the days (nights really) working in a coffee shop when we were using about 8 vac pots at any given time, many were forgotten on the burner untill all the water had went north and suffered zero damage. Breakage from careless handleing finally forced the owner to switch to drip and i almost cried. Sorta like the night the music died. DAMMIT..We're talking over 30 years ago and i still remember that coffee!!!

I would really hate to think i influenced you to up the temp and have your vac pot break so i promise to let you know if i screw up mine. It gets a lot of use, sometimes as many as 6 pots a day and thats on top of 2-3 pots thru the commercial Bunn drip ( it's tweaked a bit so does a pretty good job).

Trying not to throwing my arm out of place patting my own back here....I noticed one of the girls was drinking her coffee black and ask her if we were out of cream as she always took it white with 2 sugars. Her reply was "your coffee is good enough that i don't need cream and sugar to enjoy it"  PRICELESS!!!!!! I guess thats what it is all about.

Now to try to make it better.
