Who we are
Specialists in seaweed from Denmark
Danish Seaweed is the international face of Dansk Tang — a Danish seaweed company that cultivates, harvests and sells seaweed B2B to restaurants, retailers and producers.
We cultivate and harvest in the Isefjord and the surrounding Danish waters, and deliver only the best quality. Chefs choose seaweed from Denmark for its clean taste and the clarity of the water it grows in — fresh, dried or as powder, every delivery hand-sorted.

Why us
Cultivated, sustainable and really fresh
Three reasons the best kitchens come back to us, season after season.
Cultivated & harvested
We cultivate and harvest our seaweed in the Isefjord and the surrounding Danish waters. Real sea flavour, grown in clean water and gathered gently by hand — never compromised.
Sustainable
We harvest above the growth zone — in waders or from small boats — so the seaweed grows back. Harvesting helps remove nitrogen from the sea, and our production leaves no waste behind.
Truly fresh
Order fresh seaweed and we head straight out to gather exactly what you need — with day-to-day delivery, twice a week.
The harvest
Some of the seaweed types from Denmark
We are specialists in more than ten species — fresh, dried or as powder. It's your call.
Chorda filum
Sea spaghetti
Long, round and crisp strings that look — and can be used — like spaghetti. A delicate, fresh lemon flavour.
Laminaria digitata
Oarweed (Kombu)
A beautiful Danish kelp, perfect for a deep dashi. Tastes of cucumber and shellfish, firm like sheets of pasta.

Sustainability
The most sustainable food in the sea
Seaweed lives off the sun and the nutrients in the water — no soil, no irrigation, no fertiliser. We harvest gently above the growth zone so it regrows, and the harvest itself helps pull nitrogen out of the marine environment.
Our production leaves no waste product. Everything is used — something we are very proud of.
