About FAGE S.A (pronounced fa-yeh)
FAGE's mission is to produce high quality products. This is strongly stated in the company's motto "We would never make a product that we would not give to our children." (www.fage.gr)
One of the most remarkable achievements has been the introduction of TOTAL Greek yoghurt into the European market. FAGE's TOTAL yoghurt was the first strained yoghurt successfully launched in Europe. This success was verified by attempts of well-known multi-national industries imitating TOTAL yoghurt by creating a category called "Greek-Style-Yoghurt."
Today FAGE's selected yoghurts and cheese are enjoyed in 27 countries internationally and are found in 20,000 retail outlets in four continents.Notes to editorsThe promotion period for this competition is mainly for the months July & August and slightly varies from country to country, more information can be found on special packs of TOTAL yoghurt and on the website http://www.totalmammamia.com. The prizes will be distributed equally between the 5 participating countries. Entries can be made either through internet by visiting the special website http://www.totalmammamia.com or by post.
