What's the difference between wine cake and koji? Are they the same thing?

Broadly speaking, there is no difference.

Wine cake refers to Saccharomyces cerevisiae, also known as yeast or budding yeast.

Distiller's yeast is rice that has been strongly cooked, transferred into conidia of Aspergillus, and grew lush hyphae after heat preservation.

In the final analysis, both of them are materials used to make wine, and there is not much difference.

But there are some small differences:

① The fermented strains are different. Wine cake is Saccharomyces cerevisiae, and koji is Aspergillus. But both play the same role in brewing!

(2) There are many kinds of koji, which can be divided into:

Wheat starter is mainly used for brewing yellow rice wine;

Xiaoqu, mainly used for brewing yellow rice wine and Xiaoqu wine;

Monascus is mainly used for brewing red koji wine (red koji wine is a variety of yellow rice wine);

Daqu is used to brew distilled liquor.

Bran koji was developed in modern times, and the culture with bran as raw material was inoculated with pure mold.

Extended data

First, enzyme preparation

One of the essences of traditional koji is crude enzyme preparation. But the biggest disadvantage of traditional koji is the low enzyme activity. Modern, due to enzyme preparation

With the development of industry, in the process of wine production, some enzyme preparations were added to replace some traditional koji. Enzymes used so far

The preparation is mainly liquefied enzyme and saccharifying enzyme. Using enzyme preparation can reduce the production cost of wine, but the problem is the flavor of wine.

Affected to some extent. Therefore, in some famous wineries, traditional koji is still essential.

Second, yeast

Yeast is generally spherical, oval, oval, and some are cylindrical, lemon-shaped, triangular and so on. Some have undergone a series of budding.

After that, the grown yeast was not immediately separated from the mother, but only connected to a narrow area. This rosette structure is called pseudohypha.
