Alright... I picked up a Cory vacuum pot... got it home and did a test run with just water... PERFECT... then I did a pot with coffee and never did get to the vacuum stage... the coffee nicely filtered from the top pot to the bottom but I did not get that "woosh" at the end... then I did about 10 tries with just water... almost all of them got the "woosh"... then I did a pot with coffee... no "woosh"...

Thoughts?

Thanks!

Most likely there is a problem with the grind.  You don't need a state of the art grinder for vacuum pots, but you do need one that doesn't create too much dust. I'm not sure the cuisinart one is quite up to it.

Provided all the coffee filters down though, and it doesn't take too long it is at least working and making a brew.

I presume you are using a glass rod filter ?

+1 to the observation about grind, provided the answer to the last question is "yes." How long does it take for the coffee to return to the bottom chamber ("drawdown time")?

One thing you might try is to grind a little finer. Paradoxically, grinders in the good-but-not-great range can generate more dust on coarse settings.

Thanks for the replies... I am using a Cuisinart Burr Grinder... I set it on 2 dots below Medium towards the Coarse side... and I will say that it does produce some dust... but I am using a glass rod filter... the drawdown time is long compared to just water... it made a great cup of coffee with almost zero sediment... will try coarser grind next go around...

Recommendations on a grinder that won't break the bank?

As Johnnyb3 suggests, with some grinders it works better if you grind finer, although it seems counter-intuitive.  I'd try that before investing in a better grinder.  I don't know prices/models that well in your market, (I assume you are in the USA ?) but the Baratza ones are often recommended.  I use a Dualit re-badged Solis166, which works fine for drip and vacuum pots. Was also sold as the Starbucks Barista.  I don't think you need anything uber-expensive, just competent.

The draw-down time will always be longer than with plain water because of the filtration process, but if it is working properly you should get a bit of a "whoosh" at the end.

Right -- I really did mean "finer," definitely on the fine side of medium. Also, the timing would be interesting to know. If the drawdown is less than a minute, I'd imagine everything is working pretty well.

I also have a 166, mine is better because it is LABELED Solis 166 :P LOL!
I have also had the OPs, ....... er, ....... inexpensive grinder. There is no way to compare the two, the 166 is miles better than the Cus.

I grind a little more coarse than drip. I use a 3 minute dwell time and it works well for me.

Always make a FULL pot, you can have issues if you don't. I also use the glass rod, which filter are you using?

With that amount of time taking for the draw down because of the lousy grind from your Cuisinart grinder (too many fines), you run the risk of an implosion if there's a scratch, micro fracture, etc., anywhere on the bottom pot.

Tend to use the same grind as for drip. Always difficult to describe grind levels in words, and the same setting on my grinder probably won't be the same as on yours - but set slightly on the coarse side of medium.  I aim for 2 minutes after all water has gone up, then remove heat. Drawn down is pretty quick, and very quick with the plastic filters. (see below)

Agree with the full pot - used that to justify buying all 4 sizes of the current design Cona brewers, along with a few others.

In Conas - glass rod, apart from the French version of the Cona Rex which will only allow a cloth filter. Don't like cloth filters, so that particular one doesn't get much use.

In the Bodum Santos (I mean the original glass brewer, not the disastrous plastic one) the flat plastic filters work extremely well.  Also use them in Hario instead of cloth filters.

I'm pretty well sure the OP's problem is the grinder.
