Espresso-Grade Coffee.
Built for a Crowd.
Plenum by Bohne introduces a new approach to large-batch brewing, delivering rich, espresso-grade coffee without the burnt flavor associated with traditional bulk coffee makers.
Designed for weddings, hospitality, conferences, offices, catering, and
every place where great coffee deserves to be shared.
THE PROBLEM
Great Coffee Doesn’t Scale.
Whether serving 50 guests or 500, today’s bulk brewing methods require compromising on either quality, speed, or both.
01. Traditional Percolators
Continuously recirculates brewed coffee through the grounds, causing over-extraction and the burnt, bitter flavor commonly associated with large-batch coffee.
02. Commercial Drip Brewerss
Avoids recirculation but requires longer brew times and often fails to achieve the rich, full-bodied extraction expected from premium coffee.
03. Espresso Machines
Delivers exceptional quality—but preparing hundreds of individual servings is simply not practical for large events or commercial service.
The Industry Has Accepted the Compromise.
Until now, there has been no practical way to produce espresso-grade coffee for large groups without sacrificing flavor or efficiency.
THE SOLUTION
Meet Plenum.
Rather than refining existing brewing methods, Plenum by Bohne introduces a new brewing architecture designed to produce espresso-grade coffee at commercial volumes.
Its pressure-driven brewing system combines premium extraction with a purpose-built dual-chamber design, delivering exceptional coffee quality while eliminating the burnt flavor associated with traditional bulk brewing methods.
HOW IT WORKS
A brewing system designed to separate the water from the brewed coffee.
Unlike traditional percolators, Plenum separates the brewing process from the finished product.
As water is heated inside a pressured chamber, natural pressure forces hot water though a pipe and into the extraction chamber, where it extracts rich, espresso-grade coffee.
The brewed coffee is then falls into the bottom serving chamber—completely separate from the heated water.
Because the finished coffee is never continuously recirculated through the grounds, Plenum eliminates the over-extraction and burnt flavor associated with conventional bulk coffee makers.
