Oysters in the Dornoch Firth
We’re a proud founding partner of the Dornoch Environmental Enhancement Project, reintroducing European flat oysters to the Dornoch Firth.
DEEP is an innovative and award-winning environmental project supporting the reintroduction of European flat oysters to the Dornoch Firth after a century’s absence.
Native oysters flourished in the Firth up to 10,000 years ago before being wiped-out in the 19th century due to overfishing. Their return to the Firth for the first time in over 100 years will enrich the ecosystem of an important marine habitat.

About the project
DEEP’s shared vision is to restore long-lost oyster reefs to the Dornoch Firth, a Special Area of Conservation, enhancing biodiversity and acting in tandem with a new anaerobic digestion plant to purify the by-products created through the distillation process – an environmental first for a Distillery.
A successful re-introduction of native oysters to the Dornoch Firth as part of a ‘survivability’ trial in 2017 coincided with Glenmorangie officially opening its €6million anaerobic digestion plant at its renowned Tain Distillery.
The plant is expected to purify up to 98% of the waste water that the Distillery releases into the Firth with the remaining 2% of the organic waste accounted for by the filter feeding of the oysters.
We're proud to deliver community and staff engagement, communications support and advocacy for DEEP, and look forward to supporting the project toward a goal of some four million native oysters covering around 40 hectares. Progress has been made with 100,000 of this target already being met.

Project update: November 2024
We are delighted to help The Glenmorangie Company and Heriot-Watt University reach a huge milestone of 100,000 native oysters to the Dornoch Firth, as part of the DEEP project. The Glenmorangie Company, Heriot-Watt University and the Marine Conservation Society have worked together for 10 years to reach this achievement.
To ensure DEEP can expand its future capacity, Glenmorangie has also commissioned a new workboat, ‘Dornoch Dancer’, built by local company Leco Marine based in nearby Alness. It will allow greater numbers of oysters to be transported to reef sites and provide a bigger working platform for DEEP’s divers.
"Over the past 10 years, we’ve proudly shared the project’s story with locals and visitors. We’ve also recruited volunteers to help clean oysters, playing a key role in the project's visionary goal of creating habitat for more species, locking up carbon and improving water quality.”
