Also known as a vacuum pot. This brewer is a very old yet exceedingly entertaining way to make coffee. The whole process of the syphon brewer is a pleasing application of physics.
The brewer is built of two chambers, the lower of which is filled with water and heated to boiling point. The upper chamber, which contains the ground coffee, is then placed on top, creating a seal allowing steam to build up in the lower chamber. Eventually, this trapped steam will push the water from the bottom chamber up through a tube and a filter into the upper chamber. At this point, the water is just below boiling point making it suitable for making coffee. The brew is left to steep for a desired amount of time, during this steeping time it is important to keep heating the lower chamber. To finish the brew, the vacuum pot is removed from the heat source. As the steam cools, it condenses back into water which creates a vacuum, sucking the coffee from the upper chamber back through the filter into the bottom chamber. The grounds remain in the upper chamber separated from the coffee which is ready to be poured from the bottom carafe.
The Ratio
We recommend 26-27g of ground coffee per 12oz cup of coffee. Some people prefer to use a little more coffee than this for syphon brewing.
The Grind
We recommend a medium grind. Going too fine can stall the draw-down process to end the brewing, going too coarse can lead to longer brewing time which can make the brew overly bitter.
Steps to Brewing with the Syphon Brewer
Grind the coffee just before you start brewing. Be sure to weigh the coffee first.
Boil a kettle/pot of fresh water suitable for brewing coffee.
Fit the filter into the upper chamber, making sure it is completely flush.
Place the bottom chamber on a scale and pour in the calculated amount of hot water.
Transfer the lower chamber to a heat source (ex. Small butane burner, alcohol burner, or halogen lamp).
Place the upper chamber on top, but do not seal it yet. Sealing too soon can result in the expanding gases to push the water up into the top chamber before it is the right temperature, making your resulting brew taste bad.
Once the water starts to boil, seal the top chamber on top of the lower chamber. If you are using a controllable heat source, reduce the heat to low at this point.
The boiling water will now start pushing up into the top chamber. Look directly down on the filter to make sure it is centered, if not you will see lots of bubbles flowing from one side. With a paddle/spoon correctly position the filter by pushing it in place.
Initially the bubbling in the top chamber will be aggressive with large bubbles. The bubbles will gradually become smaller, when it becomes smaller you are ready to brew.
Add the ground coffee to the water and stir it in until it is all wet.
You will see a crust form at the top, wait 30 secs, then give it another gentle stir.
After another 30 secs, turn off the heat source.
The coffee will begin to draw down into the lower chamber, allow it to draw down completely. A slightly domed bed of grounds will be left in the top chamber.
The coffee beans we received are fresh and delicious. We grind fresh beans daily and thoroughly enjoy them. The cost of the 5 lb. bag we ordered is an excellent value too.
It's great, good coffee and same convenience as other but helps a local roaster! Just wish their mailing packaging was better than a big cardboard box. Maybe a big paper envelope? Or a smaller box?
Brooklyn, labs medium roast coffees Mexico and Peru are excellent! I’ve been drinking the coffee for a couple of years. I find it to be the best coffee I use a percolator pot highly recommend the 5 pound bag.
We tried 6 of Brooklyn Lab blends: Brazil, Peru, Mexico, Colombia, Manhattan and Brooklyn. We had previously been a (5 lb. bag) subscriber to Stumptown’s Hair Bender blend and loved it.
But Stumptown got WAY too expensive, so I shopped around to try to find a coffee that I liked as much as Hair Bender.
After trying those six blends from Brooklyn Lab (all were very good), one stood out: their excellent Brooklyn Blend! My wife and I chose it for its rich, full flavor and for the nice coffee energy boost it provides.
We just happen to live in Brooklyn, but that’s not why it’s our favorite. We also love the 5 lb. subscription price (about half the cost of what we were paying with Stumptown). We are a very satisfied Brooklyn Lab subscriber family.
My hope is that the price won’t escalate as drastically as it did with our Stumptown subscription.
I received a package of Brazil Medium Roast Coffee as a gift earlier this year and was amazed by the delicious, robust flavor! It is robust, yet smooth and
tastes wonderful! I have since ordered more for myself and sent some out as a gift too!
