One of the world’s oldest beverages - Malcolm Purinton

The video begins by illustrating medieval European monasteries as major beer producers, then traces beer's origins back 13,000 years to modern-day Israel, though the drink developed independently across multiple regions. Ancient brewing varied by available grains - rice and millet in China 9,000 years ago, and maize-based chicha in South America 5,000 years ago. The brewing process required converting starches to sugars (through chewing or germination) and fermentation via wild yeast. Ancient beer was more nutritious than modern versions due to imperfect filtering, and boiling made it safer than water. The Sumerians created the oldest surviving beer recipe in a poem to goddess Ninkasi, while Babylonians mandated daily beer rations and severely punished price gouging. In Ancient Egypt, women primarily brewed beer at home, and it served religious purposes. Beer spread to Greece by the 20th century BCE, though wine remained more popular. Medieval European monasteries pioneered large-scale production, and Central/Eastern European brewers added hops around the same time for flavor and preservation. The 1516 Bavarian Reinheitsgebot law strictly defined beer ingredients. The Industrial Revolution brought refrigeration advances, and Louis Pasteur's 1876 identification of yeast's role enabled controlled fermentation. Today's beer includes over 100 varieties, primarily lagers (cold-fermented, bottom-dwelling yeast) and ales (warm-fermented, top-floating yeast), with some hybrid styles and traditional methods like Belgian Lambics still using wild yeast.
