                                While most beer drinkers may never think about it, the U.S. Food and Drug Administration (FDA) has established a maximum allowable limit of 5% propylene glycol in alcoholic beverages. This synthetic organic compound is critical for temperature control in brewing and draft systems, ensuring consistent product quality and preventing spoilage.
