Subject: Just scored a Cory Vac Pot!!
 

Hi all!  Last night I found a 10 Cup (I think) Cory vac pot including the New Cory Rod all for $4!  It's my first vac pot so I've never used one, but I get the general idea of how it works.  I've tried it already and it brewed some great coffee, I'm just wondering if I am doing it correctly though.  When do you put the top half on?  Do you just put cold water in the bottom part, put the top half on, turn on the heat and then wait?  Or do you have the water heat up first before you put the top half on and if so how much?  Sorry about the rapid fire questioning, it's just that I've been fascinated about vac pots and now I've got one....too bad it's the stainless steel kind though, as I'm not able to see the whole process.

I don't have a Cory pot, but I do have a Yama pot and a Cona glass rod.  I can answer some of your questions though, so maybe I can help.

Though you can either preheat or not, I personally prefer to preheat the water in the carafe, with the top off.  It allows me to do a couple of things:
  • While the water heats, I can prep the other parts (grounds, cleaning, cup prep, etc.).
  • I can defer grinding until the very last minute, so that they aren't sitting out in open air for 10 or 15 minutes while the water in the bottom boils.

When I preheat, I don't let the water get too close to boiling.  I find that at some temperature before boiling, enough pressure builds up to that low-temp water makes it to the top.  Instead, I get it probably around 190 or so, assemble the pieces, then put it under high flame to finish the heating.  Unfortunately I can't tell you the exact temperature as it is difficult to measure at that point, but my goal is to put the preheated water and top together without having the water start traveling upward immediately.

When the water begins to travel upward, lower the burner to just barely enough to keep the water traveling upward.  If the burner is up too high, you will get a lot of vigorous bubbling from the bottom once all the water reaches the top.  This will jostle the glass rod and could potentially allow grounds to travel down to the bottom if too much gets caught under the rod.  The cloth/plastic filter models (Bodum, Hario, Yama) don't have this problem.

If you have more questions, please fell free to ask!  If I can help more, I will.

Looks like I have to get myself a thermometer...I think I was putting the pieces together too close to boiling and the water travels up right away.  I'll give it a try later on though, and I will post results.  Thanks!!

Tim...The Cory makes really great coffee that allows you to adjust the flavor to your taste.

My method (boil first or don't, it really doesn't matter)

Put the entire unit on the burner with the rod in place. Water will start going north at well below 200f, I've seen it appear to boil at temperatures as low as 175, so measure temperature of the water in the upper part.

I grind a little coarser than drip and add grinds to the upper bell only when the temp hits 195-200. Stir with a wooden something or other, don't want to break it with anything metal. At this point you want to reduce the heat to just enough to maintain the 200 degrees for around 3 minutes. Remove from heat.

Once removed from the heat source draw down usually takes around 20-30 seconds so 3 minutes of up top brew time works for me giving a total time of 3 1/2 minutes.

A tiny bit of sludge is normal so pay no attention. Changing the grind size, amount and/or the brew time will affect the final taste so just play around and see what you prefer.
