Reading time: 7 minutes

Brewing coffee in it is almost like a scientific experiment! Did you know that this interesting device has been around for nearly two centuries?


With its laboratory-like design, the siphon is an extraordinary coffee brewer that uses a combination of steam pressure and gravity to concoct your caffeinated beverage. It consists of two chambers for preparing your favorite drink quickly and conveniently.


By combining both immersion and filter brewing, you can enjoy a robust cup of coffee that is incredibly smooth. The siphon promotes distinct flavors from all facets of the beans - making it an ideal choice for those looking to savor every sip! This unique technique in crafting coffee has been popularized in Japan as well as many other countries across Asia.


Through this article, you will discover the origins of this appliance, understand its operating principle, and become familiar with the fundamental principles for making coffee in a siphon.


Device and principle of operation


The Siphon is an innovative coffee-making device comprising two chambers. Boiling water rises due to pressure from the lower chamber, which has been heated either with alcohol or a gas burner. This carries the hot liquid into the upper container where it mixes with ground coffee, forming a delicious brew. When the heat source is removed and reduced pressure causes gravity to take its course – brewed beverage flows back down in moments - leaving thick remains on top filter in exchange for full-bodied goodness below!

History of occurrence


In 1841, Madame Vassier revolutionized the way we use siphons today with her invention of the first modern-day version. It didn't take long for this tool to become commonplace.


Introducing the mesmerizing balancing siphon! Its distinguishing feature is that it can extinguish its flame, two chambers of this amazing device are set beside each other. Inevitably, when water is transferred from one tank to another, a weighing system starts up due to the difference in weight which causes the lights to turn off abruptly. Its awe-inspiring power and brilliance never cease to amaze me!


At the turn of the century, siphon designs from Massachusetts housewives Anne Bridges and Mrs. Sutton made their way to America, however, it wasn't until two decades later that they began production in the US. In 1915, Silex was introduced as a new type of model built with Pyrex glass - an advancement that eliminated brittleness issues thus allowing for greater commercial appeal.
The coffee world has seen a plethora of siphons emerge since then, with Hario devices being the most favored in Japan and Taiwan. In particular, the Sommelier model is both convenient and stylish, it contains two filters – metal and fabric – which offer more creative avenues for brewed coffee tasting.

KitchenAid recently released an automatic siphon that features a built-in electrical heat source, as opposed to the standard gas or alcohol burners. This model also stands out in its design with magnetic seals replacing gaskets at the device's juncture and a reusable mesh filter as well as stainless steel tubing - both more dependable than their glass counterparts. To date, it has become one of the most sought-after innovations on the market!


The recent introduction of the Siphonysta electric siphon from Tiger Corporation has revolutionized traditional coffee-making. This unique apparatus features two bowls, an inversion to the classic setup, instead of adding water first and then introducing ground beans, you pour your freshly grounded coffee into the lower chamber before heating up water in its upper counterpart. Through pressure created by steam, the hot liquid rapidly cascades down, extracting every bit of flavor out of beans before filtering back into its initial bowl.

Although the aesthetic of each device may vary, they all operate according to a similar set of principles- and we'll get into that further.

How to make coffee in a siphon


Crafting the perfect cup of coffee is an uncomplicated process that requires only a few steps - but don't let its simplicity fool you. The ratio between coffee and water employed in siphon brewing generally lies at 1:15, however, this may differ depending on the size of your machine.

 

  1. Securely fix the filter at the base of the upper chamber and attach it to the bottom part of your glass tube for a complete siphon.
  2. Stream hot water into the lower container for a speedy drink-making process.
  3. Ignite the burner and position it beneath the lower flask.
  4. Insert the extender of the upper flask into the throat of its companion below.
  5. To create the perfect cup of coffee, you'll need to grind your beans more finely than for drip brewing but coarser than for a geyser.
  6. When the majority of the liquid has shifted from the bottom flask to the top, it's time to lower your stovetop heat.
  7. Pour coffee into the water and stir gently.
  8. Leave for about a minute.
  9. Turn off the burner. The coffee will drop into the lower flask.
  10. Detach the lid and allow your beverage to cool.


In Japan, the drink is stirred twice with a bamboo spatula. Initially, this creates a whirlpool effect and makes sure that the water evenly wets all of the coffee grounds. After adding them to the upper chamber of water, it's then time for another stirring - usually gentler than before - for optimal degassing results. According to Narumi Sato, CEO of Belleville Japan, an indication of expertise in this area would be forming a dome-like shape at the base layer composed solely out of coffee grounds.


For coffee connoisseurs, the taste of coffee from a siphon is unparalleled. This brewing technique utilizes immersion to ensure that ground coffee remains in touch with water during extraction, as a result, you will enjoy an exquisitely structured and flavorful cup of coffee!


Siphon coffee is an iconic and renowned method of immersion brewing that yields a dense yet bright cup with exceptional clarity. For those seeking the perfect balance between strength, flavor, and vibrancy, this method stands out from the rest.


No matter the roast or variety, any coffee is ideal for this brewing method. Plus, a fabric or metal filter will make your brew taste more intense - both filters let through more oils than those made of paper do.

SIPHON - DEVICES FOR PREPARING COFFEE FAQ

A siphon coffee maker, also known as a vacuum coffee maker, is a unique device that uses a combination of vapor pressure and gravity to brew coffee. It consists of two glass chambers that are connected by a tube. The lower chamber is filled with water and heated, which creates steam. The steam forces the water into the upper chamber where the coffee grounds are added. Once the brewing process is complete, the heat is removed and the brewed coffee is drawn back down into the lower chamber via vacuum pressure.

Siphon coffee makers are unique because they use a combination of vapor pressure and vacuum pressure to extract the coffee flavors. This results in a clean and complex cup of coffee that highlights the flavor notes of the beans used. Additionally, the visual spectacle of the brewing process is captivating and can add to the overall coffee experience.

Because siphon brewing highlights the flavor notes of the coffee beans, it's best to use high-quality beans with complex flavor profiles. Light to medium roasts are typically recommended because they allow the flavors to shine through without being overpowered by the roasting process.

The grind size for siphon brewing should be medium-fine. The grounds should be slightly coarser than those used for drip coffee but finer than those used for French press.

While siphon brewing requires a bit more effort and attention than other brewing methods, many coffee enthusiasts find that the result is well worth it. Siphon coffee makers produce a clean and complex cup of coffee that highlights the unique flavors of the beans used. Additionally, the brewing process can be a visually captivating experience that adds to the overall enjoyment of the coffee.
