The siphon brewer (aka Vacuum Pot, Vac-Pot, Vac Pot, Coffee Syphon...) is an excellent process for making brewed coffee.  These brewers utilize a steep-and-release process that starts first with a full immersion of grounds in brew-water, then finishes by pulling the finished coffee through a filter in the draw-down phase. Siphon Brewers yield a very clean cup that helps the more subtle notes shine through, which often lost or muted in other brew methods. 

Why do we love Vac-Pots so much?  Perhaps it is because, like our sensory driven roasting philosophy, brewing with a syphon is a hands-on, sensory, almost romantic experience. 



Laboratory Quality Borosilicate Glass is durable and withstands daily use.

Beautifully Painted Ceramic Base and Stand looks great in the kitchen. 

5-Cup Capacity (approximately 22 ounces) is enough for 2-3 servings per pot.

2 Cloth Filters Included


How To Brew with a Vac-Pot 

While Vac Pots can seem complicated and intimidating, they are in reality quite simple to use.  We recommend following the below method to start, then later, after you can consistently achieve great results, tweak and play around a bit.  Remember, great artists first had to master the basic rules and techniques of their craft before they could brake them!  

1. Fill the lower pot with filtered water (for fastest results, we recommend pre-heating in microwave or on stove first).

2. Heat water to boil using burner.

3. Place filter into upper portion, feeding the spring clip through the syphon tube.  Grab the chain and pull gently to latch the clip to the end of the syphon tube. 

4. Place upper chamber into the heating lower chamber and rest it is in such a way that a seal is not formed.  (This is for 2 main reasons: first to allow the chain to rest on the bottom of the lower chamber preventing an accidental super-heating of the water*, second to preheat the upper chamber)

4. For a 5-cup Yama, weigh out 4-5 Tablespoons of whole beans and grind to a medium consistency.

5. Once the water comes to a boil, seat the upper chamber in place forming an air-tight seal.  The brew-water will rise into the upper chamber.

6. After all the water is in the upper chamber (aside from a small amount remaining in lower chamber to provide the needed steam),  start your timer and add the ground coffee.  Gently knock down the bloom with a bamboo paddle (doesn't absorb heat).  After 30 seconds perform another knock down of the bloom.

7. After 1:45 to 4 minutes, without breaking the air-lock between chambers, carefully remove from heat and watch the draw down phase (if it takes more than 30 seconds, you are likely grinding too fine). Blowing on the lower chamber or wrapping with a damp cloth can quicken the draw-down.

8. Once air starts bubbling in lower chamber, your coffee is ready. Remove upper chamber and pour (it will be hotter than you might be used to, around 200 degrees, so allow it to cool a bit).

9. Enjoy!


*Superheated water is rare,  and will never happen by following the above procedure.  Don't know what superheated water is?  Watch a quick Mythbusters video to find out.

    Amazing gift and conversational piece!

    Review by Jon L. on April 30, 2015

    The Yama CNT-5 is the perfect gift for an anniversary or special occasion. It's a must have for all coffee lovers. The gold and black artwork makes it a great table piece - and it makes great conversation when friends come over. The photos here on Venia do not do the artwork justice. When we received it we were pleasantly surprised at the detailed gold art on the piece.

    I dinged it one star because the grooves that hold the top glass piece to the bottom glass piece makes it slightly crooked. I wish they didn't use grooves, and used something a little more accurate. Most people won't even notice this issue though.

    Also, if you're going to get a siphon coffee, you should always get a model with the butane burner, which this model has. It is a must have as it gives you a lot of control over the heat. The burner itself feels heavy and durable. The thing to be careful here is that a spherical pot hovers over the burner which naturally makes water drip to where the burner is. Make sure when you wash the pot, that you don't let water drip into the burner. If that happens, just need to shake the water out and light the flame manually and keep it going until all the water vaporizes.

    I would buy it again as a gift for someone else, or for myself in the future.
