"Siphon Coffee dates back to the mid 1800s, when people were in agreement that boiling their coffee killed the taste, and so were experimenting with vacuums and vapor pressure.
While the earliest known patent for a vacuum coffee maker was filed by Loeff of Berlin in the 1830s, siphon coffee became popular thanks to a French woman, who designed the first commercially successful vacuum coffee brewer. The coffee brewer that Marie Fanny Amelne Massot of Lyons, France, known as Mme. Vassieux, designed and sold was made of two "glass balloons" held together by a frame, what we recognize today as a siphon coffee maker.At around the same time, a Scottish marine engineer was working on his own version. His Napier Coffee Pot was presented an award by The Institution of Mechanical Engineers in 1856. The siphon coffee maker's form tells you a lot about the period in which it was invented. It it as beautiful as it is functional, and in this period where coffee was taking off, with a device like this, it certainly wasn't meant to be brewed in the kitchen. You could brew in front of your guests and show off in the process.That's certainly part of the allure of siphon coffee today. As "the most theatrical of all brewing methods," as the authors of The Blue Bottle Craft of Coffee call it. And they should know; Blue Bottle is known for its dedicated siphon bar.In the United States, vacuum brewed coffee became popular thanks to the brand Silex, who made a vacuum brewer with Pyrex glass. This brew method became popular, as it was user-friendly, and empowered home coffee brewers to make great coffee. Nowadays of course, the siphon coffee maker is back, although usually seen in coffee shops as opposed to homes. Two of the most popular systems used in cafes hail from Japan, Yama and Hario."
