Sustainability

MadTree is focused on producing great beer as sustainably as possible. We believe that sustainability is a key element in our mission to be the most respected craft brewery in the region. 

When building MadTree 2.0, we utilized as much of the the existing structures as possible rather than constructing all new spaces. There are less greenhouse gas emissions associated with renovating an existing building as compared to demolition and new construction.

The existing buildings received some much-needed updates, including insulating the airplane hangar and wrapping it with lightly-colored material. This helps to reflect sunlight and reduce the amount of cooling necessary in the summer months. The insulation also helps to prevent heat from escaping in the winter. Other steps were taken to insulate and improve the energy efficiencies of the old buildings.

The new brewery is lit entirely with energy-efficient LEDs and is equipped with motion sensors. And the large windows throughout the brewery and taproom help make the most of natural light.

In the production facility, we installed a drain system that reduces the amount of time and water necessary to clean the brewery floor and maintain a safe work environment.

A new state-of-the-art CIP (Clean-In-Place) system reduces the amount of hazardous chemicals and water needed to clean vessels between batches. By employing the use of ATP rinse water testing, we can ensure the cleanliness of our brite tanks without having to release pressure, thereby reducing our CO2 consumption.

After the wort has finished boiling, it is cooled using a heat exchanger that transfers that energy to pre-heat water which is used in the subsequent batch of beer. 

At MadTree, we like to experiment with new brewing methods. We now dry hop using a new hop-dosing machine. Rather than simply dumping hop pellets into a fermenter, beer is recirculated through an external vessel containing hop pellets. This method results in a greater extraction of hop oils and aromas and reduces the amount of hops needed to achieve the same results as traditional dry hopping.

After fermentation and dry hopping are complete, the beer is clarified using a centrifuge. This filtration method increases yield, allowing us to produce more beer while using less material. This means there is less impact on the environment and more beer for you.

Additionally, all of the spent grain from the beers we brew is distributed to local farms and used as livestock feed.
