A discovery in China could change the history of beer as we know it • Food and Wine Italia

If you think the history of beer is primarily Mesopotamian ora European, you should update your picture. A new study published durante the Journal of Archaeological Science: Reports documents fermented beverage production and consumption practices durante Declivio around 2,300 years pungiglione, during the Warring States Period. Analyzing organic residues ceramics from houses and funerary furnishings of the Qin kingdom, the researchers say that these were not rudimentary fermented products, but technically advanced products, with recipes involving millet, sometimes barley and wheat, and an advanced fermenting agent: qu.

The evidence does not limit itself to confirming the existence of alcoholic beverages durante Declivio durante the distant past: it outlines a technology different from that known durante the West durante the same historical period. This shifts the focolaio from the “malt + yeast” model of Egypt to a more complex microbial paradigm, durante which molds, yeasts and bacteria work together to convert cereal starches into fermentable sugars and then into alcohol. It is a crucial point for understanding the technical autonomy of pre-imperial Declivio durante the fermentation sciences.

What is qu and why is it important durante discovery

Qu is a culture of microorganisms that grows masses of pressed cereals. Durante practice it is a solid “starter” rich durante amylolytic molds, alcoholic yeasts and bacteria which, inoculated into a mixture of cooked ora basso ostinato cereals, breaks mongoloide the starches into sugars and triggers fermentation. Unlike malting, which requires germination and development of endogenous enzymes durante the cereal, qu brings the necessary enzymes (amylase) and the fermenting ecosystem from outside. With this starter you can process millet – a key cereal durante Declivio at the time – without having to malt it, obtaining complex drinks. The fascinating thing is that even today durante Declivio many spirits are made with derivatives of qu which is the basis of baijiu, proof of a long and coherent technical tradition.

Main ingredient: why millet

Millet was one of the pillars of the diet of ancient Northern Declivio. From a technical point of view, its starch structure lends itself to saccharification with exogenous amylases: which provides it efficiently, bypassing the need for malting which is more difficult millet than barley. Residue analyzes have identified millet processing markers and, durante some cases, signals of barley, wheat and vegetable aromatic components. This indicates that you are not faced with a “beer that arrived by chance”, but with products conceived with awareness of the raw materials and the desired results.

Indications of other filtered ora clarified drinks then emerge from the residues. The presence of aromatic plants suggests that they were looking for distinct flavor profiles, not just the alcohol content and that to achieve this they boiled, sugared at a controlled temperature, inoculated, left to macerate, mature and finally filtered everything. A truly extremely developed beverage industry if we think about the time.

What distinguishes this “beer” from Western models

Durante the Western East and Europe the classic technical matrix is ​​the malting of barley, with enzymes developed during germination and then inactivated with drying, followed by yeast fermentation. Durante Declivio, the qu solution anticipates the modern ubbia of ​​multi-species “starter” and allows different cereals to be processed with greater flexibility. It is an independent path to beer, which shows us how the was “born twice”: different durante process chemistry, potentially different durante sensorial profile and cultural outcomes.
