Negotiator Tool for Big Boy


What's a Negotiator?

The Negotiator is essentially a model of the inside geometry of our brewers. You can use these tools to fit different types of filters inside the brewer, perfectly respecting the inner geometry. It helps you experience a different way to brew with the OREA Brewers using a lower bypass filter fit to reach higher extractions and explore a different brew method within the same brewing system. This device works together with flat circular papers, like the OREA flat paper Type "G" & Type "C", or Sibarist FAST flat filter (OREA special edition).

Made for the Big Boy

This negotiator is designed to work with the OREA Big Boy Brewer. It will not work with any of our other brewers, as this brewer's geometry is unique. 

Why do people love it?

By "negotiating" the paper to fit perfectly in the brewer we ensure that more water is able to travel directly downwards through the coffee bed and not around it. This leads to more consistency and better extractions. It's not just a matter of higher extractions, rather higher quality extractions. By using this method, you also open up the bed more, using more space and opening up more space in the brewer compared to the wave filters. All of this contributes to a unique profile that people love. 


A great video by Sprometheus 

A great video describing some of the ideas behind this project, used in combination with the OREA Brewer. A lot of the tricks Sprometheus shares in the video can work well for the Big Boy Brewer too!

Brew with minimised bypass

This is not a "zero bypass" solution, rather a way to minimise bypass and ensure more consistency. We prefer this approach as you can still brew quickly but reach higher extractions without much effort and time. 


Compatible papers

For the Big Boy Brewer, we recommend to stick to the flat papers we sell, the OREA flat paper Type "G" & Type "C", or Sibarist FAST flat filter (OREA special edition).

A review by Lance Hedrick

We love Lance's energy and this great video describing some of the ideas behind this project and the V3 Brewer. ‍A lot of the ideas Lance describes in these videos apply to this bigger-sized brewer too. 


The "Negotiator" is an open-source project kindly supported by Lautaro Lucero. This file will soon be available openly on Thingiverse. The idea behind this project is very much to give the community something to experiment with and explore new ways of brewing with the OREA brewing system.

A review by ARAMSE

One of our favourite YouTube channels is from ARAMSE. Check out this video for some top negotiator tips and quality humour. The tips shared by ARAMSE in this video will work well for the Big Boy Brewer too, using the Big Boy Negotiator.


Do you have to use the Negotiator in the OREA Brewers?

No - definitely not. We have developed our own wave-shaped paper as well because some folks just prefer a more hassle-free plug-and-play option. We refer to the negotiator as a power-up, rather than a necessity. It's there if you want to explore and push this brewer further - but there's no shame in keeping it simple either.
