One kilo is approx. 2 portions (a portion is roughly 500g before preparation). Fresh Mussels fished from off the UK's shores come to you next day. As with live shellfish, they do have a limited shelf life so we recommend that you consume within a few days of delivery.
A Mussel can reach maturity in a year to a year and a half reaching an average sie of approximately 40mm. Farming Mussels takes a few different forms depending on the location of where the mussels are being grown. Many are grown on ropes in the menai straits which is the stretch of shallow tidal water between the north Wales peninsular and the island of Anglesey. After harvest, mussels are typically placed in seawater tanks to rid them of impurities before marketing.
