Gower Salt Marsh Lamb is the first new product to achieve the UK GI status and becomes the 17th member of the Welsh GI family of products, joining the likes of other great produce such as Anglesey Sea Salt, Welsh Lamb, Welsh Beef and Pembrokeshire Earlies. Each family member is Welsh to the core and uniquely linked to the landscapes and seascapes which nurture them.
