Today's AGA is made in exactly the same way as it always has been. Quite simply, molten iron is poured into moulds. It's this technique that gives the castings their characteristic surface – each one is unique – and sets the AGA apart from the ubiquitous mass-produced uniformity. The modern AGA also contains state-of-the-art technology and is subject to rigorous quality controls and adherence to the latest environmental standards. Each part of an AGA cooker – and there are many – is meticulously inspected and colour checked before leaving the factory in Shropshire. This is British manufacturing as it should be, and it will be at the Chateau Impney Hill Climb.
