Buy Reggia Spaghetti Pasta online from Eorder. Reggia Pasta is produced from pure durum wheat semolina, water and no preservatives because it is the drying process of the product that gives it a natural shelf life. There are no added colourings therefore when looking at a bundle of spaghetti against the light we can see the brightness of the sun absorbed in the grain of wheat and released by the semolina.
