Question: What is one of the oldest beverages humans have produced with recipes found in Sumerian writings?

<P0-S0> Beer is one of the oldest beverages humans have produced, dating back to at least the 5th millennium BC in Iran, and was recorded in the written history of ancient Egypt and Mesopotamia and spread throughout the world. <SEP> <P1-S0> Beer is produced through steeping a sugar source (commonly malted cereal grains) in water and then fermenting with yeast. <P1-S1>  Brewing has taken place since around the 6th millennium BC, and archeological evidence suggests that this technique was used in ancient Egypt. <P1-S2>  Descriptions of various beer recipes can be found in Sumerian writings, some of the oldest known writing of any sort. <P1-S3>  Brewing is done in a brewery by a brewer, and the brewing industry is part of most western economies. <SEP> <P2-S0> Gastronomy is the study of the relationship between food and culture, art of preparing and serving rich or delicate and appetizing food, a style of cooking of particular region, and the science of good eating. <P2-S1>  One who is well versed in gastronomy is called a gastronome, while a gastronomist is one who unites theory and practice in the study of gastronomy. <P2-S2>  Practical gastronomy is associated with the practice and study of the preparation, production, and service of the various foods and beverages, from countries around the world. <P2-S3>  Theoretical gastronomy supports practical gastronomy. <P2-S4>  It is related with a system and process approach, focused on recipes and cookery books. <P2-S5>  Food gastronomy is connected with food and beverages and their genesis. <P2-S6>  Technical gastronomy underpins practical gastronomy, introducing a rigorous approach to evaluation of gastronomic topics. <SEP> <P3-S0>  Augustine (Contra Faust xix): "It is impossible to keep men together in one religious denomination, whether true or false, except they be united by means of visible signs or sacraments." <P3-S1>  Dei x): The visible sacrifice is the sacrament. <P3-S2>  It is a part of human nature to acquire knowledge of the intelligible from the sensible. <P3-S3>  Second, by sinning, humans have subjected themselves to corporeal things. <P3-S4>  There are three reasons sacraments are necessary to the salvation of humans: First, it is in the nature of humans to be led by things corporal and sensible to things that are spiritual and intelligible. <P3-S5>  The main effect of the sacraments is grace, in particular those involving Virtues and Gifts. <P3-S6>  Therefore, sacraments are necessary for man's salvation. <P3-S7>  It can be found through his writings in the "Summa contra Gentiles" and in the "Summa Theologiæ". <P3-S8>  This is the sacred sign of the invisible sacrifice. <P3-S9>  It is necessary for salvation that humans united together in the name of true religion. <P3-S10>  This is an interior effect. <P3-S11>  As can be seen, Aquinas relied heavily on Scriptural passages, as well as the writings of various Church Fathers. <P3-S12>  Third, humans are prone to direct their activity towards material things (things that can be seen and felt). <P3-S13>  Ephesians 5, 25-26: "Christ loved the Church, and delivered Himself up for it; that He might sanctify it, cleansing it by the laver of water in the word of life." <P3-S14>  Wisdom 7,1 : "she... ordered all things sweetly"; and from Matthew 25,15: "[she] gave to everyone according to his proper ability."
