Which type of grain is particularly noted for being used in Baijiu?

Baijiu, a traditional Chinese distilled spirit, is primarily made from sorghum. This grain is particularly well-suited for the production of Baijiu due to its high starch content, which is essential for fermentation. Sorghum is also valued for its ability to yield a unique flavor profile that contributes to the distinct character of Baijiu. The fermentation process utilized in Baijiu production, which often includes complex techniques and various types of koji, allows the natural sugars from sorghum to be effectively converted into alcohol and flavors, resulting in a spirit that reflects the terroir and production methods of its region.

Other grains like wheat, millet, and oats may be used in the production of different types of spirits or in certain specific regional styles, but sorghum remains the central and defining grain for traditional Baijiu, making it the correct answer.
