What is the impact of improper storage on malts?

Improper storage of malts can lead to quality deterioration, which encompasses a range of issues affecting the overall characteristics of the malt. When malts are not stored under proper conditions, factors such as temperature, humidity, and exposure to light can adversely affect their chemical composition and physical properties.

For instance, high humidity can lead to increased moisture content, which makes malts susceptible to mold growth and spoilage. Temperature fluctuations can also cause the degradation of flavor compounds and aromas essential for brewing, resulting in off-flavors or stale characteristics. Additionally, prolonged exposure to light can cause photo-oxidation, leading to further deterioration of quality.

Ultimately, these changes mean that the malt may not perform optimally during the brewing process, which can affect the final product, including the beer's flavor, stability, and appearance. Therefore, understanding the importance of proper storage conditions is crucial for maintaining the quality of malts and achieving desirable brewing outcomes.
