The Yama Syphon Brewer is a modern version of an old coffee brewer design. The process is simple and elegant, but the final product is outstanding. Simply pour 21 oz. of water into the bottom glass and heat it over a butane burner until it slowly begins to boil (the Syphon is also available with a denatured alcohol burner). If it is heating too fast and boiling rapidly, monitor the heat source to ensure a slower boil. At this point, the water will rise into the upper glass and saturate the waiting grounds. Some even recommend waiting until about 1/2 - 3/4 of the water has risen to the upper glass to dump the grounds into the top glass. Once every last drop of flavor has been extracted from the ground beans (will take approximately 2 minutes depending upon desired strength), remove the flame and gravity will draw the coffee down through the tube (and filter) into the lower glass. To serve, remove the upper glass and use the built in handle to pour a fantastic cup of coffee.

The benefits of this system are that the water heats to the perfect brewing temperature, and that complete control over the process can be maintained at all times. Simply remove the heat source when you want saturation to be complete!

Yama has specialized in hand-blown glass brewing equipment since 1978 and they've become known for their coffee siphons and cold brew towers. The siphon brewer utilizes a heat source to boil water and push it into an upper brewing chamber, then sucks the coffee down through a cloth filter and back into the bottom chamber. Hands down, it's the most involved and captivating way of making coffee. Similar to the siphon, Yama's cold coffee dripper looks more like lab equipment than a coffee maker. It uses a slow dripping process to brew a strong concoction of coffee that's destined to be served over ice.

Rated 5 out of 5 by from Amazing control! I bought this after using (very briefly) a denatured alcohol burner before realizing it's either on or off. No in between. And because of that, you end up cooking the coffee and burning it since you have no heat regulation during your brew time. You'll taste this awful burnt peanut flavor in your brews. No better upgrade than this beautiful butane burner. Easy to use, fantastic heat control at the turn of a knob, and excellent quality build. Simple to fill, and definitely no other way to go than the butane burner. The denatured alcohol is unfortunately useless to creating a wonderful cup of coffee. And the shipping was 2 day mail, crazy fast!!

Rated 1 out of 5 by from Solid body + flimsy plastic ignitor handle= broken I really want to give this burner a good review, the body is rock solid, built like a tank. But the long extended ignitor button is cheap plastic and too long. I'm not accident prone at all, and I baby my coffee gear and any other items I consider important. But this burner was broken in less than 7 hours after I received it (and it's entirely my fault), but if the ignitor was smaller or made of the same quality of build as the body, it wouldn't be broken. The whole siphon setup got bumped moving a frame (ironically setting up for a photoshoot) and knocked to the carpeted floor 4 feet below. The handle snapped off like a twig, deep inside the body. Personally, I'd likely be happier if this unit was sold without an ignitor at all. I have a lighter, and the lighter will likely outlast the ignitor used in these models, and it would be one less thing to break. All in all, it's a loud burner, but it works well. It just needs either a smaller metal ignitor, or none at all. This one is way too easy to break off.

Rated 5 out of 5 by from You need this. This is by far the best way to heat up your water/broth in a siphon system. I have tried all of the different methods out there and this one is the easiest to use and yet still has that "laboratory experiment" effect that everyone enjoys Play around with all of the butane nozzles until you find just the right size for the burner so you don't end up wasting fuel. I like to use Luciene supreme quality butane made in England. It is very clean burning and will not gunk up your $50 Bunsen burner! Colibre is also a good choice.

Rated 5 out of 5 by from Game Changer I've been using the alcohol burner my siphon came with for the last year... Super inconsistent, lots of jetting, etc... Just awful! As soon as I used the butane burner for the first time, I knew everything was well in the world. The adjustable flame allows you to adjust for temp/jetting at the beginning and throughout your brew. Plus, it's a clean and simple-looking device to compliment the rest of the siphon. This is the most important piece brewing with a siphon and getting consistent results.

Rated 5 out of 5 by from excellent burner Purchased to replace the very deficient alcohol burner that came with the hario next siphon. Couldn't be happier.

Rated 5 out of 5 by from Great product I bought this specifically for my Yama glass coffee siphon, which came with an alcohol burner. I read that the butane burners were more adjustable and cleaner so I decided to get a butane burner. I did a bunch of research to find the best one, and although you can find cheaper models online, I got this one because it was specifically made for coffee siphon brewing. When you pick it up you can feel how sturdy it is made. Has a nice weight to it and the butane fills in the bottom. Never had a problem to light it and it has it's own built in ignition so you don't need a lighter or match like you do for other models. The flame adjustment really allows me to dial in the proper flame and temperature for the coffee. Super happy with my purchase. Now, I just have to work on all the other variables to get the coffee just right!

Rated 4 out of 5 by from Easy to use, compact burner. Pretty satisfied with this burner. It's small, but robust and easy to use.

Rated 5 out of 5 by from This is a great solid product by Yama. IT IS MADE IN TAIWAN! The only thing is the ignitor is a bit delicate. It can break easy. You hv to use it with care. The flame is pretty hot and can be adjusted to precision. It can have a nice tight flame to a wider flame. Unfortunately nowhere on the package states how hot in degrees can this unit reach. But this definitely fits the Hario Syphon TCA-5.

Rated 5 out of 5 by from Clean Burning Butane Delighted with the ease of use. Filling the butane receptacle can be a little daunting and it would be nice to have some way to discern the extent of the fuel fill. The burner though is built well and heavy enough that there is no concern about it tipping or being easily moved from it's spot. Thanks for a great product!

Rated 5 out of 5 by from Controlled Heat Loving life with the Yama BN-1 burner. I can brew with my new Hario TCA-3 out on the back deck while my Lab enjoys life in the yard. Great flame control and simple sure start. Love it. Good build quality and a great match to the Hario. My favorite coffee brewing system. Can even use it while stargazing in the field.

How do you know when the burner is full. I read it should burn for aprox. 45 mins. Mine I'm only getting about 10 mins, or two brewings, but maybe I am not filling it correctly. Would it be possible for there to be a video made on the correct techniques?

Asked by: Sarahcrash
I'm not much help because I've wondered the same thing. I've never used a butane refill can before. Unlike filling a tire, there is a lot of escaping butane at the mating point. No matter how much pressure I apply it still leaks. I have no idea how much makes into the burner. I don't think it should be that way.

Can you tell me what kind of "butane" gas tank that can refill this stove? I have found that other brands might not have compatible valve to do the job.

Asked by: JackSC
As long as the tip looks like the one in the following photo, you should be good to go.

How do you refill the butane burner?

Asked by: Amander
You'l need to purchase any standard can of butane (like Zippo) then fill the burner via the valve on the underside of the unit.
