Carrageen: The Seaweed Revolutionizing Scottish Gin

Carrageen, also known as Irish Moss (Chondrus crispus), is a type of red algae that has been making waves in the gin industry, particularly in Scotland. Traditionally used in culinary and medicinal applications, this seaweed has found a new home in the world of spirits, adding unique flavours and a touch of the sea to various gins. This blog explores the history of carrageen, its uses in gin, and the distinctive tasting notes it imparts, with a particular focus on its significance in Scottish gin.

History of Carrageen

Carrageen has a long history in Western cuisine, particularly in Ireland and Scotland. Traditionally, it has been used as a gelling agent in desserts and savoury dishes and for its medicinal properties, especially in treating colds. The name "carrageen" comes from the Irish word for "little rock"—carraigín. This seaweed is commonly found on the lower shore, often under large brown seaweeds or in rock pools, and is harvested by hand to ensure sustainable growth.

Carrageen in Gin

The use of carrageen in gin is a relatively recent innovation driven by the desire to create unique, locally-inspired spirits. Distilleries in Scotland, such as the Isle of Barra Distillers, have embraced this botanical for its ability to impart a distinctive maritime flavour to their gins. For instance, the Isle of Barra Distillers use carrageen seaweed foraged from the shores of the Isle of Barra, integrating it into their Barra Atlantic Gin.

Tasting Notes

Carrageen seaweed adds a unique flavour to gin, characterised by maritime notes and a subtle spiciness. The flavour is often described as rolling across the tongue like the Atlantic surf, with a balance of floral and herbal notes, juniper, citrus, and a slight saltiness. This creates a refreshing and clean taste with a warm spice on the finish, making it a standout ingredient in coastal gins.

2. An Dúlamán Irish Maritime Gin: Although not Scottish, this gin from Donegal, Ireland, also uses carrageen along with other seaweeds to create a complex flavour profile with umami, brisk salt, and buttery oyster smoothness.

Carrageen in Context to Scotland

The use of carrageen in Scottish gin is more than just a flavour innovation; it is a celebration of local heritage and the natural bounty of the Scottish coast. Distilleries like the Isle of Barra Distillers create unique spirits and foster a connection to their homeland. The distillery's commitment to sustainability is evident in its use of recycled glass for its bottles and its efforts to support local communities and wildlife
