Andrews Flour began milling at the Comber Mill in County Down, Northern Ireland in 1722. In the late 1800s, Andrews Flour moved the milling operation to the Belfast Mill on Percy Street in Belfast, from where the company continues to operate today. The Andrews Flour range is primarily sold to commercial bakeries and food production plants via bulk tankers and 25kg bags across the island of Ireland. The Mortons Flour range is also produced at Andrews Flour. Due to the strong heritage and unique reputation of the brand throughout Ireland, Mortons Flour is the consumer facing brand that is distributed to retailers in 1.5kg, 2.0kg and 3.0kg bags. The full milling and packaging operation is completed on the Percy Street site in Belfast.
