Porto-Muiños, 90's
We embark on the conquest of the sea
In the Atlantic waters off the coast of Galicia began our journey to conserve the sea. We immersed ourselves in the underwater forests to understand them and to ensure that algae take their place in our daily diet.
The study and dissemination of the organoleptic qualities of algae were and continue to be our goal.
Rosa Mirás and Antonio Muiños, coastal Galicians.



A family project overlooking the sea
This small cannery with an international vocation, specialized in organically produced seaweed, also dedicates space and time to the production of other products from the sea of Galicia: delicate canned sea urchin roe, monkfish liver whose taste and texture has obtained a good rating from specialists, mussels with seaweed, seaweed infusions, gluten-free organic pastas made with vegetable and seaweed flours and other products with all the flavor and richness of the Atlantic.

Sunlight and waters
beaten, the secret
of our sea

Products by Porto-Muiños: vegan, vegetarian and organic, of course.
On many of our products you will find the V-Lavel quality seal, which identifies vegan and vegetarian products internationally. You will also see the European organic certification seals, which guarantee that we have produced them in an environmentally friendly way and free of chemical components or processes.


Regulated and sustainable manual harvesting with underwater dives in authorized areas
The sea of Galicia is very fertile. The confluence of the Atlantic Ocean with the Cantabrian Sea creates a marine system of incomparable richness. The marine strip, between parallels, that passes through Galicia is the richest in the world in marine flora due to its hours of sunshine. We take care of the sea and we take care of our underwater vegetable garden, because it is clear to us that the sea is our source of life and the future of planet earth.
We feel like fish in the water but with our feet on the ground.


Pioneers in seaweed cultivation
Algae cultivation as the future, for us it is the present.
We are the first and only company in Spain that cultivates seaweed in the sea. In Porto-Muiños the blue economy is nothing new. We know that we have to get wet to ensure a sustainable sea. With our plantation we avoid the overexploitation of the coastline and the spores of our crops repopulate the nearby coast regenerating the ecosystem. Seaweed cultivation does not require arable land, significant fresh water or pesticides.
The health of the sea is the health of the blue planet.


Navigating together
A walk breathing the sea breeze, its energy, its essential elements, its vitamins and minerals. A basket full of sea vegetables®. A bowl of soup with seaweed from Galicia. We are coastal people paired with the knowledge of researchers, universities, chefs and people of the sea.
Research and design sailing in the same boat. The sea is everything and everyone has their place aboard this project. A journey without end in which we learn to discover new horizons.


Growing and learning
Innovation is a process. It is observing to inform our brains. It is breaking rules to create. It is to unite scattered things. It is to evolve to generate new ideas. To innovate is to grow and have fun, it is to find the unexpected on the road that leads to other places. To innovate is our way of feeling the sea and life.
