Vacuum coffee maker with magnetic coupling system

A method of forming a seal between an upper brewing unit and a lower carafe in a vacuum coffee maker, the method comprising the steps of:

• coupling the upper brewing unit to the lower carafe using a magnetic coupling system wherein the magnetic coupling system includes a lower magnetic coupler disposed in a first collar of the lower carafe and an upper magnetic coupler disposed in a second collar of the upper brewing unit, wherein the first collar of the lower carafe is positioned over an upper portion of a vessel and included an upper landing and a lower landing inwardly extending from the upper landing to define a stepped configuration therebetween;
• forming a seal between the upper brewing unit and the lower carafe;
• aligning a first set of engagement features disposed on a lower landing inwardly extending from the second collar of the upper brewing unit with a second set of engagement features disposed on a lower landing inwardly extending from the first collar of the lower carafe;
• and
• locking the first set of engagement features of the upper brewing unit with the second set of engagement features of the lower carafe to retain the seal therebetween.
