Brewing.
Thinking.

Beer is one of humanity's oldest beverages. Evidence of fermented grain drinks dates back over 13,000 years, with some of the earliest confirmed recipes found in ancient Mesopotamia and Egypt. For early civilisations, beer was not a luxury. It was nutrition, currency, and communal ritual all at once.

The Sumerians documented brewing in detail around 1800 BCE in the Hymn to Ninkasi, a tribute to the goddess of beer that doubles as a brewing recipe. In Egypt, workers building the pyramids received a daily ration of beer. It was safer than water, more caloric than bread, and deeply woven into daily life.

In medieval Europe, monasteries became centres of brewing knowledge. Monks refined fermentation techniques, developed new styles, and kept the tradition alive through periods of instability. Many of Belgium's most celebrated beer styles trace their lineage directly to monastic brewing traditions that survive to this day.

The industrial revolution brought mechanisation, refrigeration, and the rise of lager. Brewing shifted from local craft to industrial production. By the twentieth century, a handful of global producers dominated the market, and diversity narrowed sharply.

Then came the craft beer renaissance. Beginning in the United States in the 1970s and spreading globally, independent brewers reclaimed variety, locality, and quality. Today there are more active breweries worldwide than at any point in history, and beer culture has never been more diverse.

That history matters for sustainability. Beer is rooted in place, in water, in agriculture, and in community. Those roots are exactly what a serious sustainability approach seeks to protect.

The word sustainability has become so common it risks losing its meaning. But its history is specific, and understanding it matters for anyone serious about applying it.

The concept has roots in 18th century German forestry. Hans Carl von Carlowitz wrote in 1713 about the need to harvest timber no faster than forests could regenerate. The principle was simple: do not consume more than can be renewed. That idea, in essence, is still what sustainability means at its core.

For most of the following two centuries, the concept stayed largely within natural resource management. It was not until the 1970s that sustainability entered broader public and political discourse. The 1972 Club of Rome report, Limits to Growth, presented modelling that showed unchecked industrial and population growth would eventually collide with planetary boundaries. It was controversial, but it shifted the conversation.

The 1987 Brundtland Report gave sustainability its most cited definition: meeting the needs of the present without compromising the ability of future generations to meet their own needs. It was a landmark moment, bringing environmental thinking into mainstream development policy.

The 1990s and 2000s saw sustainability become a corporate concern, and with that came the rise of greenwashing. As companies rushed to appear responsible, the gap between rhetoric and reality widened. Weak sustainability frameworks, which allow natural capital to be substituted by economic capital, became the norm.

Today the urgency is undeniable. Climate change, biodiversity loss, and water scarcity are no longer projections. They are present conditions. For the brewing industry, which depends on water, agriculture, and stable climates, that urgency is not abstract. It is operational.
