If you can find one of these at a decent price, you owe it to yourself to try it. It‘s a wonderful throw-back to a kinder, slower era.

I have read about the ressurgence of interest in vacuum coffee makers in the past few years and wanted to try one, having remembered that my grandmother had a Sunbeam C30 that she used.
I looked on Ebay and was discouraged by the prices and good not find any in local thrift stores, until recently. For those of you hoping to get into this branch of the hobby, don‘t dispair...
My first was a Cory wide-mouth for $36, the second for $5 and the latest for $1.50. It all depends on when and where you find them. (I also have a Silex wide-mouth that works very well.)
I use these on an electric burner on medium heat, being careful not to let it get too hot. I have also found a single burner hotplate that works well and will be great to use on the table during dinner parties.
It is important to read Mark‘s Vacuum Coffee maker FAQ elsewhere in this site.
I grind the my homeroast for a fine drip. and place in the upper chamber after inserting the "Cory" rod. This assembly is then set aside until the water is at the right temp, i.e., 190 to 200 degrees F.
I then place the upper chamber on the lower, seating it firmly. The water usually immediately begins its journey "north", into the upper chamber. When all of the water has gone north, the hot air from the lower chamber "boils" past the filter rod and stirs the coffee above. I usually stir the coffee with a wooden spoon to make sure that it gets mixed well.
When it has brewed for three to four minutes, I take it off the heat, and the coffee begins its journey "south" past the filter rod. It is very fun to watch! The vacuum will ‘suck" all of the water through the grounds, leaving them almost dry.
The resulting cup is very flavorful, with almost NO sediment. Contrary to what others have said about the Cory rod, I think it works very well, and is MUCH easier to clean and deal with than the cloth filters for Silex or Hario. The Cory rods even work well in my Silex, even though the Silex was meant to use with a cloth filter.
It‘s far more fun to recycle one of these antiques than paying through the nose for a Cona. Highly recommended.
