Sustainably Harvested Sonoma Coast


Make this nutrient dense food a part of your daily nutrition

  • Plant based protein

  • Raw food

  • Local and Regenerative


We harvest the seaweed by hand in the summer months along the Sonoma coast, and dry it for your year-round enjoyment. Deliciously edible seaweed varieties flourish in the chilly, nutrient rich waters of the rough-and-ragged Sonoma coastline. Collecting occurs early in the mornings on June and July low tides.  The collected algae are rinsed and dried on screens in the sun.  Strong Arm Farm triple-rinses the seaweed we collect for your sand-free eating enjoyment.

Seaweed Varieties

Types of Seaweed

(Laminaria setchelii)

Best in soups of all kinds (miso, chicken, chili, curry, Japanese dashi stock, etc.) The silky algin/alginates of this seaweed act as a thickening agent and help break down fibers in beans (aka gas reduction.)  Kombu has the highest content of naturally occurring glutamates, which imbue a satisfying umami taste and mouth feel.



Very mild, thin, iridescent when wet, and particularly high in protein. Can be toasted and crumpled into small flakes and easily added to dishes like a spice. Or massage with oil and flavorings for a kale-chip-esque experience.

Harvested in minor quantity:



Particularly rich in Iodine and Iron. Sought after by herbalists.



Traditional use in seaweed salads, high in calcium.

Articles in Support of Seaweed

"I lived in Japan for several years and got in the habit of making dashi. When I use your kombu [from the Sonoma Coast] in dashi it just tastes so much deeper than when I get the supposedly 'good stuff' from the Japanese market."  Andy R.
