Each blend of tea uses a different type of seaweed, Rogers said, including bladderwrack, dulse, kelp and sea lettuce. He buys only sustainably harvested seaweed from sources like the Atlantic Holdfast Seaweed Company in Deer Isle.
Once the seaweed is harvested, Rogers said it is dried and milled into flakes. Then, he said, “I get to do the easy part: blending it with other ingredients. The final product is a loose-leaf tea that you can brew just like regular tea.”
