Touqu generally refers to the first section of wine, which is the better type. Tequ is better than Touqu; Erqu refers to the second section of wine, which is slightly worse than Touqu. Quality level: the special song is better than the first song, and the first song is better than the second song, which is gradually used today.

Everyone who often drinks liquor knows that there is a kind of qu in liquor, which is classified into: Tequ, Touqu, Daqu and Erqujiu. So what is the difference between these qus?< /p>

It is named according to the length of fermentation and storage, also called quantity and quality grading. It stipulates that Tequ should be stored for three years, Touqu should be stored for two years, Daqu should be stored for one year, and Erqu should be stored for half a year. Qujiu is the general name for liquor that uses Daqu as a saccharifying fermentation agent, that is, Qujiu; Tequ refers to special-grade Daqu liquor, which is also a particularly good Daqu liquor. Qujiu has three different fermentation stages. The main fermentation stage is when grains are saccharified and fermented to produce alcohol; followed by the acidification stage, which produces lactic acid, acetic acid, and acetic acid; and finally the aroma production stage, which produces esters and aromatic compounds.

Touqu, Erqu, Sanqu, etc. are the names given to different fractions of wine due to different distillation times. That is to say, the naming of the length of fermentation and storage time, which stipulates that Tequ should be stored for three years, Touqu should be stored for one year, and Erqu should be stored for half a year.

The differences between various Qu wines:

Tequ: refers to special Daqu wine, that is, particularly good Daqu wine. It refers to the first stage of wine after distillation.

Daqu: It is cultured by mixing wheat and barley with a certain proportion of peas. It is generally solid-state fermentation, and the brewing process is extremely complex. The wine produced is of good quality, and most of it is famous and high-quality wine. For example, most strong-flavor liquors are brewed using this method.

Touqu, Erqu, etc.: are the names given to wines with different fractions due to different time of receiving wine during distillation.
