Wine curds are sold in large supermarkets, such as Carrefour and Walmart. In addition food stores, food courts are sold. In addition, all major e-commerce platforms are also available.

Shuwu, generally written as wine quill. In the strongly steamed white rice, moved into the conidia of the mold, and then keep warm, the rice will be lush growth of mycelium, this is the liquor quartz. The amylase produced by Aspergillus will saccharify the starch inside the rice, therefore, it has been used as raw material sugar at the same time as malt since ancient times, and used to make wine, sweet wine and bean paste. Those who use wheat instead of rice are called maitake.

Scattered quarts, i.e., liquor quarts in a loose state, are made from grains that have been ground or crushed and on which microorganisms (mainly molds) grow at a certain temperature, air humidity and moisture content. The loose song has been used in China for thousands of years in the history of song making. For example, the ancient "Huangzi Qu", rice quartz (especially red quartz).

Block quarts, as the name implies, are wine quarts with a certain shape, which are made by adding the raw materials (such as flour) to an appropriate amount of water, kneading them well, filling them into a mold, pressing them down to fix their shape, and then cultivating the microorganisms under a certain condition of temperature, moisture and humidity.

Historical Origin of Wine Quill

The origin of wine quill is not known, and the earliest text on wine quill is probably the Zhou Dynasty work "Shujing - Speaking of Destiny", which reads, "If you make wine, you can only make quill". Analyzed from the scientific principle, the wine is actually from the evolution of moldy grains.

The production technology of the wine in the Northern Wei Dynasty "Qimin Essentials" in the first comprehensive summary, in the Song Dynasty has reached a very high level. The main performance: complete varieties of wine quartz, perfect technology, wine quartz, especially in the south of the small quartz saccharification fermentation power are very high. The modern wine quartz is still widely used in the brewing of yellow wine, white wine and so on.

In the production technology, due to the microorganisms and the brewing theory of knowledge, the development of the liquor song jumped to a new level. The original brewer's yeast was moldy or sprouted grain, which was improved and made into a brewer's yeast. Due to the different raw materials and production methods used, and the different natural conditions of the production areas, the varieties of liquor quartz are colorful and varied. During the Song Dynasty, the types of Chinese wine-making quills and their manufacturing techniques were basically finalized. In later generations, there were some improvements on this basis.
