True North OystersSeafood lovers can enjoy oysters sourced from a co-operative of small-scale shellfish farmers based on the west coast of Scotland, who belong to the Scottish Shellfish Marketing Group.This is the first time that True North’s product will be stocked in Aldi’s Scottish stores.Grown in mesh bags that are laid on low trestles on the shore at the low tide mark, the oysters grow naturally by feeding from the nutrient-rich tidal flows of Scotland’s seas.
