A new type of dairy company

"We created Deep Sea Dairy to bring humans closer to nature. As cheesemakers it's our responsibility to look for better ways to live."

Don Harrington
"Modern dairy farming is an environmental catastrophe. Cows are kept cramped and unsanitary conditions and are impregnated just to keep milk flowing. Nearly half of the US is dedicated to livestock production. Dairy farming alone is responsible for 4% of all anthropogenic climate change. We waste 1000 gallons of water to make just 1 gallon of milk. We can’t go on like this."
Mark Linneaus
Cheif Scientist

We have the technology to look beyond the land and out to sea. Our oceans hold the key to our survival.

‍Though they were once hunted to near extinction, whales now patrol our world’s seas in huge numbers. A single gray whale, when milked, has the productive capacity of 500 dairy cows. Whale milking also has an incredibly an low environmental impact. Whale milk requires no additional feedstock. No water consumption. No antibiotics. And no ethical compromises.

All milk used for our cheese production is sourced from wild, healthy whales.

At Deep Sea Dairy, we believe in more than just cheesemaking. We’re committed to supporting scientific research and improving animal welfare. We have pledged to donate 20% of all profits towards studying whale ecology, ensuring their wellbeing, and preserving marine habitats. We are on a path to achieving B-corp certification and will be carbon negative by 2025.
