You must know that ever since the catastrophe struck, the food that is planted now is not enough to feed the survivors, let alone the consumption of food resources for brewing alcohol.
Besides the main ingredients necessary for brewing, the quality of yeast is also a critical issue. In this era, the weather has become extremely unpredictable, so the vast majority of ordinary people simply don't have the conditions to store yeast for long periods.
