There is an old saying among Chinese distillers that captures the very essence of their craft.
Water is the blood of wine, Qu is the bone, and grain is the flesh.
— Traditional Chinese brewing proverb
Water plays an irreplaceable role in the making of traditional spirits. Throughout history, wherever fine wines and spirits have emerged in China, pristine springs have always been close by. Today, when we raise a glass of strong-aroma baijiu, we are tasting not only the essence of the harvest, but also the natural breath of the landscape from which it came.
The Ancient Wisdom of Seeking Water
Through centuries of practice, ancient distillers discovered a fascinating truth: even if they used the exact same grains and fermentation starters, changing the water source would entirely alter the spirit's flavour. The Ming-dynasty scholar Song Yingxing noted this in his encyclopaedia of traditional crafts, The Exploitation of the Works of Nature, emphasising that brewing requires the clearest of springs.
Historically, craftsmen sought out pure waters because water is much more than a physical medium for steeping grains and steaming the mash. It is the cradle for fermentation. The natural mineral composition of the water determines how well the microbes in the fermentation pits can thrive, which in turn shapes the final aroma and mouthfeel of the spirit. Without good water, even the finest grains cannot reach their full potential.
Glacial Springs and the Geography of Mianzhu
Mianzhu, resting at the edge of the Sichuan Basin, has been a renowned distilling town since ancient times. Its secret lies at the foot of the Longmen Mountains. The region receives over 1,200 millimetres of rain a year. This abundant rainfall merges with glacial meltwater from the high peaks, filtering slowly down through layers of slightly acidic yellow clay and rock to become exceptionally clear, sweet underground springs.1
This glacial spring water is exactly what strong-aroma baijiu requires. Beneath Mianzhu, old fermentation pits host over a thousand species of microbes. The pristine water provides an ideal environment for these invisible artisans to flourish, allowing them to create the rich, complex aromas unique to the region. It is largely thanks to these waters that the China Alcoholic Drinks Association named Mianzhu a "World Fine Spirits Characteristic Region" in 2019.
The Lingering Taste of the Mountains
Ultimately, the quality of the water is revealed in the cup. At the Qifu distillery, the craftsmen continue to follow traditional methods that respect the natural environment. Take the flagship Bainian Qifu · 8, for example. This pure-grain, strong-aroma baijiu is crafted from sorghum, wheat, rice, glutinous rice and corn. During the solid-state fermentation process, which takes place in yellow-mud pits under a red-grain cap for about sixty days, the clear waters of the Longmen Mountains mingle deeply with the five grains.
It is this water that unlocks the deepest sweetness of the harvest. When you pour a cup of Bainian Qifu · 8, you are met with a smooth entry and a gentle journey across the palate. The spirit offers a full pit aroma that concludes with a lingering, nutty, caramel-like finish. This harmonious balance of strength and softness owes its existence directly to the glacial springs at the source.
In a fast-paced world, it is a quiet pleasure to pause and sip in moderation. What we drink is the gift of the harvest, the patience of time, and the soft echo of mountain springs that have flowed for thousands of years.
