My first experience trying blue cheese was something to remember. Before then, I would only eat cheese if it was in the form of a pizza topping. The mouldy blue patches and the grainy structure of this ‘new’ cheese I had tried was alarming, and for a good reason I hated it- but not for long. After a while, the new tang and strong aroma became addictive and something I would search for, rather than avoid. This story can also be true for baijiu. Comparing Western liquors to cheddar and mozzarella, blue cheese would be the baijiu of the cheese world. The differences are just harder to see at first glance.
Baijiu is a colourless liquor just like vodka, and we know what vodka tastes like as we know what to expect. Expectations are one thing, but if you’ve ever taken a sip of baijiu you will know that the reality is very different. It’s horrible, or is it? Maybe if we were to change our perspective of baijiu, we could find a hidden passion for this ancient treat. Here we will uncover the secrets that make baijiu so fundamentally different from any other spirit from the West. At the end of the day, we live in Sichuan which is a birthplace and one of the biggest producers of baijiu- the world’s most popular liquor.
From Farm to Factory
Anything that contains sugar or starch can be fermented to alcohol. For a fruit spirit you can simply mash the apples and wait for them to ferment. Compared this to baijiu which is made from grain, sorghum (which is traditional and looks like low cost brother of corn). Other grains can also be used such as corn, barley, rice and wheat. Yibin’s favourite spirit, Wuliangye (Five Grains Liquid) contains, surprisingly, five grains. Grains are heavy on starch and not sugars, as with whiskey, bourbon and vodka also starting from starch- so what’s the difference? This is the first turn baijiu diverts from western methods.
The West germinate seeds and then dry them to create sweet malt. With the use of self-produced enzymes, the grain is forced to initiate change from starch to sugar. In Chinese baijiu “qu” is used, which is basically an external source of microbes which do the job for you. This results in differences in taste from the very beginning of the baijiu’s journey.
Bugs at Work
These sugars are then fermented with yeast. In the West, strict procedures are usually apply, which involves brewing slurry malt and adding only a selected strain of yeast to grow, to get one specific outcome. However, in China, you just dump everything in a pit in the ground- literally. Here is where the tradition comes into place. This is the main reason why you can’t just start exactly the same baijiu production in the heart of France, or even in a different place in China. The pit is where the magic happens. Over time, a wild brew of yeast and microorganisms is formed, which is perfected and sustained by continuous usage. Qionglai, Luzhou and Yibin (just to name a few), around Chengdu have hundreds of pits in uninterrupted use for more than 500 years. This perfect chaos produces an extreme variety of fragrant compounds, other than ethanol. The West considers these chemicals to be undesirable, due to their razor sharp taste, however in baijiu this feature is the heart of the liquor.
Catching the Spirit
In the West, the fermentation is done in slurry, which is then heated to boiling and the alcohol is distilled. Carefully controlling the temperature helps avoid excessive distillation of lighter (methanol) or heavier (strong taste) molecules. In comparison, baijiu slurry is solid, as you dig out solid wet fermented grains. In order to liberate the alcohol out of the slurry, they are rushed through with stream. This is a very old technique, but it has an immerse impact on taste. If you distil with steam, heavy fragrant molecules are captured in rising vapour and condensed in distillate. Only steam distillation can extract these heavier flavourful molecules. The exact opposite applies in vodka, where multiple distillations eliminate “undesirable taste”.
Time is of the essence
The last step for making baijiu is aging. But whisky is aged as well! Right? Right?! Yes. However, whiskey gets its taste and colour from the wooden barrel. Baijiu needs ceramics, but not for taste, it has all the components. When baijiu ages it recombines the high concentration of the heavier flavour molecules to create new richer aromas. Everyone who has tasted baijiu knows that the taste can be overwhelming- but that’s the point.

Western liquors are based on improvements in distillation, sanitation, refining technology to bring the clean and desired specific taste. It reflects Western culture: approach and mentality. Baijiu is like China itself as its old, traditional and produced by chaos moulded to perfection. It’s unified yet extremely diverse. Baijiu is China. This is how we should approach it. It isn’t vodkas brother; it’s barely its second cousin. It has its own rules, history and culture. You may never like it, that’s fine, but when you take your next sip do not expect cheddar, try to find the blue cheese in it.
