Bladder wrack

Fucus vesiculosus aka Rockweed
Harvested to
Oct
Harvested from
- Apr

The name derives from the air bladders in its fronds that help the plant sit up in the water, maximising exposure to light and absorption of nutrients.

This plant grows abundantly in the mid shore, spending an equal amount of time both under and out of water.

High polyphenol (antioxidant) levels give this plant a bitter taste.

Typical uses

Ideal for nutraceuticals and low inclusions as a fantastic stealth health ingredient.

Spiral wrack

Fucus spiralis aka Flat wrack
Harvested to
Dec
Harvested from
- Feb

A small olive brown plant that grows with a twist in the frond.

It thrives on the upper shore of rocky coastlines, just below Channelled wrack. Living on the upper shore, it is very tolerant of desiccation and can survive out of the water for long periods.

Typical uses

Spiral wrack is a little-known seaweed with great potential. It does not have the astringency that is characteristic of other seaweeds in the wrack family, making it fantastic in broths, bakery, in fact in just about anything savoury.

Knotted wrack

Ascophyllum nodosum aka Atlantic kelp, rockweed or egg wrack
Harvested to
Oct
Harvested from
- Apr

It grows in long fronds with egg-shaped bladders that keep the plant floating when the tide comes in to maximise exposure to the Scottish sunlight!

An abundant species on sheltered coastlines and estuaries. It often is the dominant species of the intertidal zone but rarely found on exposed coasts with high wave action.

Typical uses

Our powdered knotted wrack makes for a fantastic additive to smoothies, baking and seafood pastas. It is also a very nutritious supplement, perfect for nutraceuticals.

Months of wild harvest seaweed production

Samples available to you from our archive

We have developed a detailed knowledge of harvest seasons. Specifically, it may be possible to pick small quantities of a variety early in a season, but we delay first harvest until the rates reach commercial scale. Indicative seasons for our key species are given below. Please contact us if you would like to learn more about production months.
