A beer producer, or brewer, is a craftsman specialising in the elaboration of beer, a fermented beverage obtained by the fermentation of malted cereals (primarily barley) with water, hops and yeast. Beer is the most consumed alcoholic beverage in the world and one of the oldest, with an extraordinary diversity of styles and flavours.
A brewer masters a production chain that goes from cereal malting to packaging in bottles, cans or kegs, via mashing, fermentation and conditioning. Whether running a craft brewery of a few hectolitres or a multinational producing billions of litres, the brewer is above all a passionate lover of flavour and fermentation.
Beer is one of humanity's oldest fermented beverages. The first archaeological traces of brewing date back to 5,000 BC in Mesopotamia and Egypt, where beer was considered a staple food and an offering to the gods. The Sumerians even had a goddess dedicated to it, Ninkasi.
In Europe, it was the medieval monks who developed and codified the art of brewing. Benedictine and Cistercian abbeys produced beers to sustain pilgrims and fund their works. It was in 1516 that Duke Wilhelm IV of Bavaria promulgated the famous Reinheitsgebot, the German purity law which limited beer ingredients to water, barley and hops.
The industrial revolution of the 19th century radically transformed brewing with the invention of artificial refrigeration and Louis Pasteur's mastery of fermentation. In the 20th century, industrial consolidation gave birth to global giants, while since the 1980s the American craft beer movement has triggered a worldwide renaissance of artisanal brewing.
Beer production begins with mashing: malted cereals are milled and mixed with hot water to convert starch into fermentable sugars. The resulting wort is filtered, then boiled with hops that contribute bitterness, aromas and preservation properties.
Fermentation is the key step: yeasts transform sugars into alcohol and carbon dioxide, while producing a multitude of aromatic compounds. Top fermentation (ales, at 15-25°C) gives fruity and complex beers, while bottom fermentation (lagers, at 5-12°C) produces cleaner and more refreshing beers.
Conditioning and maturation allow the beer to clarify and develop its aromas. Final packaging in bottles, cans or kegs requires particular attention to hygiene and carbonation maintenance to guarantee quality through to the consumer.
According to data from Kirin Holdings and the IWSR:
Over 1.9 billion hectolitres of beer produced worldwide each year — Kirin Holdings, 2022
China has been the world's leading beer producer by volume since 2002 — Kirin Holdings
Over 10,000 craft breweries in the United States in 2023 — Brewers Association
Over 2,500 active breweries in France in 2023 — Brasseurs de France
Beer represents approximately 75% of global alcoholic beverage volumes consumed — IWSR
Lager / Pilsner — bottom fermentation, dominant world style, fresh and thirst-quenching
Ale — top fermentation, very diverse family: pale ale, IPA, amber ale, brown ale
Stout / Porter — dark roasted beers, Guinness leading, coffee and chocolate aromas
Wheat beer / Weizen — unmalted wheat, banana and clove notes, Bavaria and Belgium
Belgian beer — Trappist, abbey, saison, gueuze, lambic, extraordinary diversity
IPA (India Pale Ale) — intense hopping, emblematic craft beer style, tropical aromas
Spontaneous fermentation — lambic, gueuze, kriek, Belgium, wild fermentation with indigenous yeasts
Smoked beer — Rauchbier, Bamberg, Germany, malt dried over beechwood smoke
Sour beer — Berliner Weisse, Gose, Flanders, natural acidity from lactic bacteria
Barrel-aged beer — ageing in bourbon or wine casks, global premium trend
Low / no alcohol beer — strongly growing segment, advanced dealcoholisation technology
Craft beer — small production, local ingredients, creativity, market exploding worldwide
Beer is going through a dual revolution. On one side, the large industrial groups (AB InBev, Heineken, Carlsberg) are consolidating their global positions through massive acquisitions. On the other, the craft beer movement continues its spectacular expansion, with thousands of new microbreweries opening every year on every continent, driven by growing demand for authenticity and flavour diversity.
Sustainability and environmental footprint are major issues for the brewing industry. Beer production is highly intensive in water (approximately 7 litres of water per litre of beer), energy and cereals. Pioneer breweries are investing in renewable energies, brewing water recovery and organic farming.
Finally, the globalisation of styles is a fundamental trend. Japanese brewers are inspired by American IPAs, Australian brewers reproduce Belgian gueuzes, while American brewers are rediscovering traditional European styles. This cross-pollination considerably enriches global brewing diversity.
