What Is The Difference Between Irish Moss And Sea Moss?

If you’ve been under the impression that Irish moss and sea moss are the same thing, don’t worry, you’re not alone. Many people believe the terms ‘Irish moss’ and ‘sea moss’ are interchangeable. However, that’s not accurate. Despite the confusion, sea moss and Irish moss are two different things.

Irish moss, or Chondrus Crispus, is a species of algae. It most typically grows in cooler climates, including Europe and Canada. During the Irish potato famine, Irish moss was eaten in abundance - hence the name. Irish moss has flat leaves, and is typically a dark purple color. 

Sea moss is a more generic term, but typically when you see it used it’s referring to is genus gracilaria. This is thinner and more stick-like. It comes in a variety of colors.

The two are often confused, partly due to the abundance of sea moss versus the rarity of Irish moss. It’s possible that if you’ve searched for Irish moss before you’ve been directed instead to sea moss. There’s also a popular variety of gracilaria that’s purple, Jamaican purple sea moss, which is sometimes mistaken for Irish moss.

There are enough similarities between the two that which one you buy isn’t that important. While fans might argue for the mineral content of Irish moss, the price makes it unattainable for many. You also have to be sure of the supplier, as unaware sellers may try to pass off gracilaria as Irish moss.

What is the difference between seaweed and sea moss?
