Our Story


Josh Rogers, founder, Cup of SeaCup of Sea makes loose-leaf herbal & caffeinated teas featuring Maine seaweeds.


Why? Seaweeds are a true superfood. They contain around 60 minerals vital to human health, including iodine, potassium, calcium, magnesium, manganese and phosphorous, plus trace elements like chromium, vanadium and boron. They also provide vitamins (A, Bs, C, E, K), DHA omega oils, essential amino acids, anti-inflammatories and antioxidants. They taste good too!

My own taste for seaweed goes back to my great grandmother, Nanna K, who loved snacking on dried dulse, a reddish-purple algae long popular in northern Maine, Canada, Iceland and Ireland. She brought that tradition with her when she and Gramp emigrated from Canada's Maritimes in the 1930s to work in Maine's shoe mills.

My interest deepened over the 12 years I lived in NYC working as a restaurant guide editor at Zagat and on dining content strategy at Google. It was 2013 when I hit on the idea of making seaweed teas. But it wasn't until I quit my job to move back to Maine in 2016 that I was able to finally start Cup of Sea.

Two years later, I opened Heritage Seaweed, a boutique shop in Portland, Maine, specializing in all things seaweed. It's also now the home of Cup of Sea, where we blend all of our seaweed teas.
