Best ways of Manual Brewing. 3 /5 cup Timemore syphon of quality and experimentation! One of the most impressive ways of making coffee. It’s a science! By heating the bottom chamber the pressure forces water up into the upper chamber to mix with the ground coffee. Once mixed the coffee is drawn into the lower chamber as the pressure drops, creating a vacuum effect via a filter, and voila, your coffee is brewed! Timemore Syphon team has created this work of art with design and elegance in mind. The wooden handle is a reflection of their hourglass logo, not only well designed but they had safety in mind too. The handle is further away from the hot glass than most syphons (1. 5cm between fingers and the lower bowl) to prevent accidental burns. Crystal clear borosilicate glass finish which is highly heat resistant giving you peace of mind that safety has not been compromised.
