Handmade butter with Atlantic sea sat and dulse (dried seaweed) harvested from the North Coast of Ireland. Shelf life of 12 weeks. Weight 125g Allison and Will Abernethy inherited their butter making skills from previous family generations and in 2005 decided to turn their hobby into a business. Initially going to local agricultural and vintage shows to demonstrate how cream is churned and turned into butter, they soon realised there was a demand for their product.
