We want to be a regenerative social enterprise. A business that heals the earth and creates wider social cohesion. We know how to do this through food and drink forestry, fermentation and composting. The challenge is one of scaling the labour required for this in an economy dependent on maximising profits that too often come at the cost of social and ecological value.

Our idea for growth is to model our business goals and activities on the most efficient and abundant ecosystem in nature – the forest.  When we decided to found a brewery, we were inspired by this quote about Trees:

Old Trees:

"Make oxygen, sequester carbon, fix nitrogen, distill water, accrue solar energy as fuel, create complex sugars and food, create micro-climates, provide a rich habitat for many creatures, change colour with the seasons and self-replicate."

The idea grew was that we would mimic the services of Old Trees with Old Tree Brewery. We fix nitrogen in the soil by composting organic matter, returning it to soil and spreading gardens; we distill water in the brewery; accrue solar energy as fuel to run our rickshaw; create complex sugars and food; our drinks change colour with the seasons and by sharing knowledge with others we aim to self-replicate...

By investing time into planting trees and edible landscapes we can also help: make oxygen, create micro-climates and provide a rich habitat for many creatures..

After several years exploring all these aspects we concluded that we needed to focus on more efficient production of just our live botanical drinks to enable us to reinvest the profits into being a regenerative enterprise. We have now established Old Tree Brewery Ltd. which we run in central Brighton for the live botanical drinks supply and we are also in the process of converting our former partnership into a community interest company to deliver the social and ecological impact of our work in community land regeneration.

All of the money donated through this page will directly support the creation of our first permanent Drink Forest Garden Project at ROCK FARM. It will also support our work in carbon sequestration with biochar and land regeneration with composting.

We plant trees on a regular basis, always voluntarily, as the brewery is not yet at the position where it can invest or subsidise this activity (as was its founding purpose).

The saying remains true that –

“the best time to plant a tree is 25 years ago, the second best time is now”.

We are planting an maintaining forest gardens several days a week now, we want to share this work with the world and it would be brilliant to have the capacity to do this. expand this wer


We have found the most challenging part of imitating an Old Tree is how to sequester carbon as a food and drink producer.. How to use less power, and how to remove it from our atmosphere where there is already a dangerous imbalance? The more we grow the more energy we need...and our power is mainly coming from fossil fuels in civilisation today. Some of the ingredients we use have very high carbon footprints from their production process. We need fridges and machinery that have a high impact, just to be viable food and drink producers. Is it inescapable to contribute to global environmental decline? Is the idea of a regenerative enterprise impossible?

For the challenge of storing carbon, we've created a new tool for carbon negative food and drink production – The Terra-preta Trailer. 

We have co-designed and built a carbon negative power station to produce bio-char as a bi-product of the heat captured for live brewing and cooking. An educational tool, the intention it to demonstrate far and wide how to build the most fertile organic soils for restoration agriculture.
