Why is malting not carried out in wine making?

Here's why:

* Malting is the process of germinating grains (like barley) to convert starches into sugars. This process is essential for brewing beer, as the sugars are then fermented by yeast to produce alcohol.

* Grapes already contain naturally occurring sugars (fructose and glucose). These sugars are the primary source of alcohol in wine. No malting is required.

* Winemaking focuses on the fermentation of grape juice. This involves crushing the grapes, extracting their juice, and then adding yeast to convert the natural sugars into alcohol.

Therefore, malting is not a necessary step in winemaking. The process is fundamentally different from brewing, which relies on malted grains for its sugar source.
