Owning the Yama 3-Cup Tabletop Siphon
Invented way back in 1830, siphon brewing is a more scientific solution to your caffeination requirements than you might normally use. Siphon, or vacuum brewing as it's sometimes called, is a method of making coffee that relies on vapor pressure and vacuum force to aid in the extraction process. Yama's beautiful 3-Cup Tabletop Siphon makes use of these same principles to brew a clean, almost tea-like cup of coffee.
To brew using the siphon you'll need water, ground coffee, and a heat source. Each siphon includes an alcohol burner that works well with isopropyl or denatured alcohol, but Yama also offers a supplemental butane burner for greater temperature stability. You'll start by filling the bottom half of the siphon with water while resting the top half above it. Both halves of the siphon are connected by a glass tube that can be fitted with filter (the Yama siphon includes a reusable cloth filter). Using your heat source you'll boil the water in the bottom globe, as the water expands into gas it will rise into the top half of the siphon for as long as the water remains boiling. At this point you'll want to add your ground coffee (each siphon includes a dual purpose scoop and stirrer). Brew times will ultimately depend on your preferences but you'll want to stir your grounds occasionally to ensure even brewing. When you're done brewing simply remove your heat source, your brewed coffee will be drawn back down through the filter and into the bottom globe. At this point, you can remove the top half of the siphon and begin serving. The term "cup" as used by Yama means about 3-4 oz of coffee per cup.
